I. STATEMENT OF THE ISSUE
The 109 patent, owned by Rambus, broadly claims a method of storing
information in dynamic random access memory (DRAM). The claimed method
stores (writes) data to a memory device based on certain instructions.
Specifically, representative claim 1 requires (1) providing control information to
the memory device, wherein the control information includes a first code which
specifies that a write operation be initiated and (2) providing a signal to the
memory device, wherein the signal indicates when the memory device is to begin
sampling write data. The providing a signal element of claim 1 is the focus of
this appeal. In a lengthy specification, the 109 patent describes the provision of
the claimed signal in numerous embodiments, including one that discloses a delay
value that indicates to the DRAM when the data specified in the request packet
will begin to be sent.
Farmwald, a prior art patent also owned by Rambus, describes a method of
storing information in DRAM that mirrors the delay value embodiment in the
109 patent. Farmwald refers to the provision of its signal as outputting a value to
the memory device, wherein the value is representative of the delay time. The
Board found that Farmwalds delay value embodiment anticipates the 109 patents
claim 1, and therefore affirmed the Examiners rejections of all the claims on
appeal.

The issue on appeal is whether the Board reasonably construed the
providing a signal element of claim 1 and whether substantial evidence supports
the Boards finding that Farmwald teaches that element, and therefore anticipates
claims 1-25 of the 109 patent under 35 U.S.C. 102(e).
II. STATEMENT OF THE CASE
The 109 patent, entitled Method of Controlling a Memory Device Having
a Memory Core, issued to Barth, et al., on October 23, 2007. JA31-76.1 It is the
tenth patent in a large and heavily litigated patent family addressing data storage
techniques.
On May 15, 2009, the United States Patent and Trademark Office (PTO)
granted a request by a third-party, NVIDIA, for reexamination of all 25 claims of
the 109 patent. On May 15, 2009, the Examiner rejected, inter alia, claims 1-25
as anticipated by Farmwald. On November 14, 2009, the Examiner issued an
action closing prosecution that, inter alia, finally rejected claims 1-25 as
anticipated by Farmwald. Following responses from Rambus and NVIDIA, on
February 26, 2010, the Examiner issued a right of appeal notice, maintaining the
rejection of claims 1-25 as anticipated by Farmwald. JA10975-11060. Rambus
appealed to the Board of Patent Appeals and Interferences (the Board), NVIDIA
responded, and the Examiner answered. JA13973-14008; JA15088-15106;

JA15663-65; JA15682-15694. On May 4, 2011, the Board held an oral hearing.
JA17440-17480. On September 1, 2011, the Board affirmed the Examiners
rejection of claims 1-25 as anticipated by Farmwald. JA1-24. On October 3,
2011, Rambus submitted a request for rehearing. While that request was pending,
NVIDIA withdrew from the proceedings. On March 22, 2012, after considering
Rambuss rehearing request, the Board refused to alter its decision. JA17519-
17535. This appeal followed.
III. STATEMENT OF THE FACTS
A. DRAM Technology in General
This case concerns the way computers store information in memory. At a
fundamental level, a computer stores (writes) information in and retrieves
(reads) information from the computers memory. Br. 4. As part of the process,
the computer stores information in memory cells. JA33, Figs. 1A and 1B. To read
from and/or write to these memory cells, such read/write operations often involve a
memory controller and a processing device of a computer such as a central
processing unit (CPU). For example, the memory device can communicate with
the memory controller, which in turn can communicate with the CPU. The
communication path between the memory device and memory controller is called a
bus. See Br. 4; JA55, col. 4, ll. 8-26.

B. The 109 Patent
The 109 patent broadly claims a method of controlling data transfers to and
from a memory device. Claim 1 is representative:
A method of controlling a memory device having a memory core,
wherein the method comprises:
providing control information to the memory device, wherein the
control information includes a first code which specifies that a write
operation be initiated in the memory device;
providing a signal to the memory device, wherein the signal
indicates when the memory device is to begin sampling write data,wherein the write data is stored in the memory core during the write
operation;
providing a first bit of the write data to the memory device during an
even phase of a clock signal; and
providing a second bit of the write data to the memory device during
an odd phase of the clock signal.
JA74-75 (emphasis added).2
Simply stated, the method of claim 1 tells the
memory device whatto do (write data) and whento do it (when the signal tells
it to). Per the claim language, an instruction to write data happens through
control information. Id. And the timing of when to write data is determined by
providing a signal. Id.
The 109 patents specification explains these elements in more detail. First,
it distinguishes the prior art systems, which it characterizes as inflexibly
2The last two elements of claim 1 are not at issue here.

determining the timing ofa data transfer . . . by the timing of the request for the
data transfer. JA58, col. 10, ll. 27-28. In these prior art systems, a data transfer
request is sent and the transfer has to begin a predetermined number of clock
cycles after the request. JA58, col. 10, ll. 32-34. The inventors of the 109 patent
asserted that this renders prior art systems inflexible with respect to how control
and data signals may be interleaved to maximize the use of the transmission path.
JA58, col. 10, ll. 36-39.
In contrast, in the 109 patent, the timing of the request and the actual
transfer of data can vary. JA58, col. 10, ll. 44-51. The timing can be dictated by a
strobe signal, which occurs at various times depending on the transaction. Id.
Or the timing can be varied without the use of strobe and terminate signals.
JA58, col. 10, ll. 55-56, 64-67. In the non-strobe embodiment, timing is controlled
by the provision of a delay value, which tells the memory when the data
specified in the request packet will begin to be sent relative to the time at which the
request packet is sent. JA58, col. 10, ll. 57-60.
The 109 patent has been widely litigated by Rambus in at least seven causes
of action.3

D. The Boards Decision
In a detailed 23-page decision, the Board affirmed the Examiners rejection
of all claims of the 109 patent as anticipated by Farmwald. The Board focused on
claim 1, which requires (1) providing control information to the memory device,
wherein the control information includes a first code which specifies that a write
operation be initiated and (2) providing a signal to the memory device, wherein
the signal indicates when the memory device is to begin sampling write data.4
The Board made findings as to which embodiments in the 109 patents
specification are encompassed by claim 1.
The Board found that the 109 patent describes at least two embodiments
for operating a DRAM, which the Board referred to as strobe and non-strobe
embodiments. JA3. The Board found that [i]n both embodiments, a memory
device (e.g., a DRAM) receives command control information causing it to begin a
process for reading data from, or writing data to, the memory core. JA3-4. The
Board further found that in the strobe embodiment, a strobe signal tells the
memory when to write information. JA4. In the non-strobe embodiment, a
delay value tells the memory when to write information. JA3, 5. The Board
4The Board also discussed claim 7. JA7. However, that claim has not been
separately argued on appeal.

found that both embodiments allow the timing of the write operation to vary,
offering a level flexibility not found in the prior art. JA4-5. In the inflexible
prior art, the data transfer timing [is] based on a fixed number of clock cycles
after the clock cycle on which a request packet arrives. JA6.
With these findings in mind, the Board applied the prior art patent,
Farmwald, to claim 1. As to the first element of claim 1, providing a write
instruction via control information, the Board found that Farmwald discloses a
request packet that contains control data that in turn includes control
operations such as writing data. JA8. As to the second element of claim 1,
providing a signal to indicate when to start writing, the Board found that, in
Farmwald, the request packet controls the timing of the write operation either by
directly select[ing] a certain register in the slave DRAM memory device which
stores the (delay value) timing information or indirectly by indicat[ing] pre-
selected (delay value) access times. JA8. The Board further found, with respect
to the second element of claim 1, that Farmwalds claim 28 recites this feature:
outputting a value to the memory device, wherein the value is representative of
the delay time; and outputting a second operation to the memory device, wherein
the second operation code instructs the memory device to internally store the
value. JA8. In sum, the Board found that Farmwald discloses using request
packets which can vary the data block transfer time in [a] manner which is similar

9
to the alternate (delay value/non-strobe) embodiment of the 109 patent (D3), to
determine when to read or write data from a memory device. JA7-8. For these
reasons, the Board affirmed the Examiners rejection of all claims of the 109
patent as anticipated by Farmwald.5
Rambus requested that the Board rehear its appeal because Rambus alleged
that the Board entered a new ground of rejection by relying on a different aspect of
Farmwald than the Examiner relied on to support its anticipation finding.
JA17483. While that request was pending, NVIDIA withdrew from the
proceedings. JA17513-15. After considering Rambuss request forrehearing, the
Board denied the request, stating that its initial decision tracks the Examiners
reliance on the delay value signal in Farmwald. JA17527. Rambus does not
appeal this aspect of the Boards decision, and thus no longer contends that the
Boards decision includes a new ground of rejection.
5The Board also reversed the Examiners non-statutory double-patenting
rejections. JA21-23. The Board further stated that its affirmance of the rejection
of all claims as anticipated by Farmwald renders it unnecessary to reach other
issues, such as the Examiners decision to refuse to adopt the Requestor NVIDIAsremaining proposed rejections. JA23.

IV. SUMMARY OF THE ARGUMENT
Rambuss arguments boil down to a few key points. First, Rambus asserts
claim 1 must be given a narrow construction that requires that the signal
immediately incite a write operation. Second, Rambus asserts that the providing a
signal element of claim 1 must be given a narrow construction that requires that
the signal be sent separately from and subsequent to the write request. And,
third, Rambus asserts that claim 1 must be given a narrow construction that
excludes the alternate delay value embodiment found in its own specification.
Rambuss arguments fail, however, because claim 1 does not include any of these
limitations, and there is nothing in the specification that requires that they be read
into the claim. In fact, the terms signaland providing a signal are not defined
in the specification, but are simply used in an ordinary and customary way.
Without Rambuss extraordinarily narrow claim interpretation, which the
Board properly rejected, Rambus cannot avoid its own prior art patent, Farmwald.
Farmwald teaches a method of storing information in a memory device that not
only facially meets all of the elements of claim 1, but also precisely mirrors the
alternate delay value embodiment found in the 109 patent. Given the close
resemblance of Farmwald to the 109 patent, the Board properly affirmed the
Examiners rejection of the claims of the 109 patent based on anticipation.

V. ARGUMENT
A. Standard of Review
Rambus has the burden to show that the Board committed reversible error.
In re Watts, 354 F.3d 1362, 1369 (Fed. Cir. 2004). Anticipation is a question of
fact. In re Baxter Travenol Labs., 952 F.2d 388, 390 (Fed. Cir. 1991). What a
reference teaches is a question of fact. Para-Ordnance Mfg., Inc. v. SGS Imps.
Intl, Inc., 73 F.3d 1085, 1088 (Fed. Cir. 1995).
This Court upholds the Boards factual findings unless those findings are not
supported by substantial evidence. In re Gartside, 203 F.3d 1305, 1316 (Fed. Cir.
2000). Substantial evidence is something less than the weight of the evidence but
more than a mere scintilla of evidence,In re Kotzab, 217 F.3d 1365, 1369 (Fed.
Cir. 2000), and means such relevant evidence as a reasonable mind might accept
as adequate to support a conclusion.Consol. Edison Co. v.NLRB, 305 U.S. 197,
229 (1938). Further, ifthe evidence in [the] record will support several
reasonable but contradictory conclusions, then this Court will not find the
Boards decision unsupported by substantial evidence simply because the Board
chose one conclusion over another plausible alternative. In re Jolley, 308 F.3d
1317, 1320 (Fed. Cir. 2002).
During reexamination, as with original examination, the [USPTO] must
give claims their broadest reasonable construction consistent with the
Case: 12-1480 Document: 28 Page: 18 Filed: 11/29/2012

specification. In re ICON Health & Fitness, Inc., 496 F.3d l374, 1379 (Fed. Cir.
2007) (citingIn re American Acad. of Sci. Tech Ctr., 367 F.3d l359, l364 (Fed. Cir.
2004)). This Court thus reviews the USPTOs interpretation of disputed claim
language to determine whether it is reasonable. In re Morris, 127 F.3d 1048,
1055 (Fed. Cir. 1997).
B. A Reasonable Claim Construction and Substantial Evidence
Support the Rejection of Claims 1-25 for Anticipation
1. The Board Properly Construed the Term Signal
Claim 1 requires providing a signal to the memory device, wherein the
signal indicates when the memory device is to begin sampling write data.6 JA74.
The Board reasonably construed the term signal to encompass various kinds of
indicators that tell the memory when to begin a write operation. Looking to the
specification for guidance, the Board found that the specification neither provided
a definition for signal nor a disclaimer precluding other generally understood
signals from being included in the patents claimed signal.Id. Rather, the Board
properly found that the patent uses the term signalbroadly, using signal and
information interchangeably when discussing similar operations of starting and
ending the reading, writing, or transmission of data. JA21. In addition,
referencing an IEEE dictionary definition, which Rambus itself had relied on in
6Rambus offers no separate argument regarding dependent claims 2-25.
Therefore, all of the claims stand or fall together with claim 1. In re Dance, 160
F.3d 1339, 1340 n.2 (Fed. Cir. 1998).

other litigation and which NVIDIA pointed to as support for the plain meaning of
the term signal (see A15095 n.5), the Board found that the specifications broad
use of the term signal is consistent with the understood meaning of the term in the
relevant art, the physical representation of data. See JA10, 14, 21.
2. Rambuss Alleged Errors as to the Boards Interpretation
Have No Merit
a. The Term Signal is not Limited to a Transmission
That Incites Immediate Action
Rambus asserts that the term signal should be limited to a transmission
that incites action. Br. 21 (emphasis added). Rambus further argues that the
claimed signal must incite immediate action (i.e., start now). Br. 30, 34.
Rambuss argument conflicts with the plain language of the claim. Claim 1 simply
states that the signal indicates when the memory device is to begin storing data:
providing a signal to the memory device, wherein the signal
indicates when the memory device is to begin sampling write data,
wherein the write data is stored in the memory core during the write
operation;
JA74 (emphasis added). Claim 1 does not require that the write operation begin
after a particular amount of time after the signal, never mind immediately. If such
a limitation were meant to be included in claim 1, the drafter of claim 1, who
repeatedly used wherein to limit the claim, could have included it. Instead, there
is not even a suggestion of the limitation that Rambus argues applies.

Without any support in the claim for the limitation, the specification would
have had to limit the claim language explicitly. As the Board noted, to limit the
meaning of a claim, the patentee must demonstrate[] a clear intention to limit the
claim scope using words of manifest exclusion or restriction. JA9. There are no
such words here. To the contrary, even in the so-called strobe signal
embodiment, cited by Rambus as the proper reading of claim 1, the read or write
operation does not immediately follow the signal, as there is some delay before the
write operation occurs. See, e.g., JA58, col. 9, ll. 37-51 (discussing the slight
delay between the strobe signal and the transmission of data). Similarly, the read
or write operation does not immediately terminate after a signal. JA58, col. 9, ll.
60-62 ([d]ue to intrinsic circuit delays, the DRAM does not instantly terminate
data transmission upon receipt of a terminate signal.).
b. The Claimed Signal Does Not Have to be Sent
Separately or After the Write Command
Rambus also argues that the claimed signal must be decoupled from the
write command, which it argues means that the signal must be sent separate from
and subsequent to the write command. See, e.g., Br. 21. While it is true that one
object of the invention (among many) is to provide a mechanism to decouple
control timing from data timing (JA55, col. 3, ll. 33-34), nothing in the claims
requires decoupling. Claim 1 does not recite the term decouple, nor does it
recite separate or subsequent to or otherwise require that the signal and write
Case: 12-1480 Document: 28 Page: 21 Filed: 11/29/2012

7/30/2019 109k
22/47
15
command be performed separately or in a certain order. Rather, claim 1 simply
recites a plurality of steps including providing control information to the memory
device and providing a signal to the memory device.
The only specific discussion of decoupling timing information occurs in a
briefsection of the specification called Decoupled Data Transfer Control
Information. JA58, col. 10, l. 25. This section addresses the specifications
delay value embodiment, which Rambus inexplicably asserts is not decoupled
(or even claimed in the 109 patent). As the brief discussion in this section of the
specification indicates, decoupling of timing information does not require that
various types of control information be sent separately; it merely requires that the
timing of the data control information be flexible so that the timing between the
request to begin a write operation and the actual data transmission vary. JA58, col.
10, ll. 25-67. What is also clear from this discussion in the specification is that
there are multiple ways in which the invention can be structured to be flexible over
the prior art, either by sending data transfer control information (timing
information) separately from the command control information (write instructions)
as described in the strobe signal embodiment orby using a variety of delay
values to vary the latency between the request packet (with the write instruction)
and the actual data transmission. Id.

16
A discussion in the specification immediately following the decoupling
section sheds further light on the meaning of decoupling. There, the
specification provides:
As mentioned above, the fixed timing between requests and data
transmissions renders prior art systems inflexible with respect to how
control and datasignals may be interleaved. . . .
* * *
The ability to vary the timing between the transmission of a
request packet and the transmission of the data specified in the
command control information makes it possible to interleave the
information . . . in variations that were not previously possible.
JA59, col. 11, ll. 1-6, 22-26 (emphasis added). Thus, it is the fixed timing of the
prior art systems, not whether the control and data instructions are sent separately
from each other or in a particular order, that determines how flexible the system is.
Significantly, the specification here refers to control and data information as
signals. Id.
Regarding the separate from and subsequent to language from the
specification cited by Rambus as a requirement of claim 1, this is simply another
attempt by Rambus to import a limitation from the specification into the claim. In
discussing one strobe signal embodiment, the specification does state that data
transfer control information is sent separate from and subsequent to command
control information. JA57-58, col. 8, l. 63 to col. 9, l. 2. However, because data
transfer control information can be sent separate from and subsequent to

7/30/2019 109k

17
command control information in one embodiment, does not mean that it mustbe.
That is, simply because a particular embodiment has the capability to send
information in a particular way does not mean that it is required by the claims.
Limitations from parts of the written description, such as details of an embodiment,
cannot be read into the claims absent a clear intention by the patentee to do so.
See, e.g.,SRAM Corp. v. AD-II Engg, Inc., 465 F.3d 1351, 1359 (Fed. Cir. 2006)
(holding it is error to narrow a claim by reading in a limitation). There is no clear
intention here.
Moreover, the mere fact that the providing a signal element is written after
the providing control information element in claim 1 does not mandate that the
elements be performed in that order. This Court has held that although a method
claim necessarily recites the steps of the method in a particular order, as a general
rule the claim is not limited to performance of the steps in the order recited, unless
the claim explicitly or implicitly requires a specific order. Baldwin Graphic Sys.,
Inc. v. Siebert, Inc., 512 F.3d 1338, 1345 (Fed. Cir. 2008); see also Altiris, Inc. v.
Symantec Corp., 318 F.3d 1363, 1371 (Fed. Cir. 2003) (holding that ordering in the
preferred embodiment cannot be imported into the claims when there is not any
statement that this order is important, any disclaimer of any other order of steps, or
any prosecution history indicating a surrender of any other order of steps.). Here,
the claim language does not require a specific order.

Rambus citesMantech Envtl. Corp. v. Hudson Envtl. Servs. Inc., 152 F.3d
1368, 1376 (Fed. Cir. 1998) for the proposition that elements one and two of the
109 patent must be performed in order. However, inMantech, the order was
required for the claim to make sense; each step simply could not be performed
before the prior step had occurred. For example, inMantech, step 1 required wells
for monitoring groundwater. Id. at 1375-76. Step 2 required that acid be
introduced into the wells. Id. at 1376. Acid could not be introduced without the
wells first being provided. Step 3 introduced an aqueous solution of ferrous ion
into the already acidified groundwater.Id. The claimed solution could not be
provided to the acidified groundwater without the groundwater already having the
acid. Step 4 introduced a hydrogen peroxide solution into the groundwater that
undergoes a reaction in the presence of said acidic conditions and said ferrous
ion.Id. Obviously then, the hydrogen peroxide solution must be added after the
acid and the ferrous ion. As a result of this claim language, the Court inMantech
held that the sequential nature of the claim steps is apparent from the plain
meaning of the claim language. Id. Here, in contrast, the plain meaning of claim
1 does not require such ordering.
In fact, elements one and two of claim 1 are written in a fashion that actually
confounds ordering. They contain a first code without identifying a second code
and contain a write operation step that is clearly out of order:

19
providing control information to the memory device, wherein
the control information includes afirst code which specifies that a
write operation be initiated in the memory device;
providing a signal to the memory device, wherein the signal
indicates when the memory device is to begin sampling write data,
wherein the write data is stored in the memory core during the write
operation;
A74 (claim 1).
In light of the lack of clarity regarding the ordering of elements one and two,
Rambus relies on elements three and four of claim 1 to imply an overall ordering
scheme. Br. 27-28. However, elements three and four clearly occur in order and
are written quite differently from elements one and two:
providing a first bit of the write data to the memory device
during an even phase of a clock signal; and
providing a second bit of the write data to the memory device
during an odd phase of the clock signal.
A74 (claim 1). In any event, this Court has held that the ordering of some steps
does not compel the ordering of others. See, e.g.,Altiris, 318 F.3d at 371 (holding
that certain steps were grammatically and logically required to be performed in
order while others were not). Thus, Rambus cannot successfully argue that the
claim language or specification requires that the write operation instruction
occur before the claimed signal that merely indicates when the operation is to
happen.

c. The Delay Value Embodiment is not Unclaimed
Rambus argues that the term signal cannot be interpreted to include the
specifications delay value, and therefore that the delay value embodiment is
unclaimed. Br. 21-22. In support of this point, Rambus argues thatdecoupling
(which Rambus defines as the signal being sent separate from and subsequent to
the write command) represents the essence of the 109 patents advance, and that
the delay value embodiment of the specification is not decoupled. Br. 42. As
explained above, decoupling is not defined as the signal being sent separate from
and subsequent to the write command. Rather, decoupling refers to varying the
timing between the write command and the actual transfer of data. Thepatents
delay value embodiment varies this timing and is explicitly discussed in the only
section of the specification discussing decoupling. JA58, col. 10, ll. 25-67.
Thus, if the essence of the invention is decoupling, the delay value embodiment is
consistent with the essence of the invention, which supports the Boards reading of
the claims.
Rambus also argues that the alternate [delay value] embodiment is
described as operating without signals, and, therefore, since signals are
required by claim 1, the delay value embodiment cannot be encompassed by the
claims. Br. 22. The premise is incorrect. The delay value embodiment is
described as varying the timing of data transfer without the use ofstrobe or
Case: 12-1480 Document: 28 Page: 27 Filed: 11/29/2012
-
7/30/2019 109k
28/47
21
terminate signals, not without the use ofa signal generally. JA58, col. 10, ll.
55-56 (emphasis added).
Lastly, Rambus asserts that the delay value is only discussed in the
specification in terms of the prior art. Br. 45, 50. This argument makes no sense.
If the delay value embodiment were only in the prior art, it would not be explicitly
identified as an alternate embodiment. JA58, col. 10, ll. 52-56. Moreover, even
a cursory reading of column 10 of the patent, which discusses the prior art, shows
that the discussion of the delay value embodiment is completely separate from and
distinguished from the discussion of the prior art. The discussion of the prior art
identifies situations in which the timing of data transfer is dictated by the timing
of the request for data transfer by a predetermined value. Id., col. 10, ll. 27-39.
The delay value embodiment, by contrast, discloses how the controller may vary
the latency between the write request and the data transmission using a delay
value. Id., col. 10, ll. 52-67. Thus, while certain predetermined values might be
discussed as being used in the prior art, the particular variable delay value
discussed in the 109 patents alternate embodiment is not.
All that claim 1 requires of its signal is that it indicate to the memory
device when the memory device is to begin sampling write data. JA58 (claim 1).
The 109 patents delay value meets this limitation because it indicates when the
data will be sent to the memory device:
Case: 12-1480 Document: 28 Page: 28 Filed: 11/29/2012
-
7/30/2019 109k
29/47
22
In this embodiment, the [request] packet contains a delay value that
indicates to the DRAM when the data specified in the request packet
will begin to be sentrelative to the time at which the request packet is
sent.
JA58, col. 10, ll. 57-60 (emphasis added). Thus, by its plain language, the delay
value embodiment mirrors the language of claim 1, supporting the conclusion that
it is encompassed by the claims. Courts are reluctant to exclude an embodiment
unless, for example, [a] claim construction that embraced both alternative
embodiments would be unreasonable. Rolls-Royce, PLC v. United Technologies
Corp., 603 F.3d 1325, 1335 (Fed. Cir. 2010).7
Given the disclosures in the
specification, it is certainly not unreasonable to claim the delay value embodiment,
which explicitly tells the memory device when to begin sampling data just like the
claimed signal.
d. The 109 Patent Does Not Exclude the Delay Value
Embodiment Simply Because the Parent Patent
Includes It
For the first time on appeal, Rambus argues that because the parent of the
109 patentthe 914 patentexpressly claims the alternate delay value
7 See also Oatey Co. v. IPS Corp., 514 F.3d 1271, 1276 (Fed. Cir. 2008)(absent
disclaimer or estoppel, claims should normally be interpreted to include disclosed
embodiments); Verizon Servs. Corp. v. Vonage Holdings Corp., 503 F.3d 1295,1305 (Fed. Cir. 2007) (rejecting a proposed claim interpretation that would exclude
disclosed examples in the specification);Invitrogen Corp. v. Biocrest Mfg., L.P.,
327 F.3d 1364, 1369 (Fed. Cir. 2003) (finding the district courts claim
construction erroneously excluded an embodiment described in an example in the
specification, where the prosecution history showed no such disavowal of claim
scope).

23
embodiment, the 109 patent clearly cannot. Br. 46; JA17615-17659 (914 patent).
This argument is waived and does not warrant any consideration because it was
never made to the Board. In re Watts, 354 F.3d at 1367 ([I]t is important that the
applicant challenging a decision not be permitted to raise arguments on appeal that
were not presented to the Board.); see also In re Alonso, 545 F.3d 1015, 1022
(Fed. Cir. 2008) (refusing to consider Appellants newly minted argument).
Nevertheless, even if Rambuss so-called claim differentiation argument
were to be considered, it fails on the merits. There is nothing precluding Rambus
from incorporating similar features into claimed inventions of different family
members in a patent tree. Some iteration of the delay value embodiment is
certainly encompassed by the claims of the 914 patent: [t]he method of claim 6
wherein the step of transmitting a start indicator is performed by transmitting a
delay value in the control information. JA17658 (claim 7). And some iteration of
the strobe signal embodiment is also encompassed by the claims of the 914 patent:
[t]he method of claim 6 wherein the step of transmitting a start indicator is
performed by transmitting a strobe signal a selected number of clock cycles after
transmitting the control information.Id. (claim 8). That does not mean that the
strobe signal and delay value embodiments in the specification are not claimed
by the 109 patent that recites abroader signal,not a strobe signal or delay
value. Were Rambuss argument as to the delay value correct, the claimed
Case: 12-1480 Document: 28 Page: 30 Filed: 11/29/2012
-
7/30/2019 109k
31/47
24
signal in the 109 patent could also not encompass any of the strobe signal
embodiments in the specification because they were already claimed in the 914
patent.
Moreover, as discussed above, by reciting the term signal, rather than
strobe signalor delay value, claim 1 of the 109 patent is broader than the
claims in the 914 patent that specifically recite strobe signal and delay value.
This supports an argument that the 109 patent, which only refers generally to
signals,includes, rather than excludes, the delay value embodiment.
In fact, rather than support Rambuss argument, the claim language in the
914 patent actually advances the Directors position. In the 914 patent, both a
strobe signal and a delay value are described as a start indicator. . . that
specifies when the data transfer opertation is to begin. JA17658 (claims 6-8)
(emphasis added). Given that the 914 parent patent describes its delay value as
a start indicator. . . that specifies when the data transfer operation is to begin,
and claim 1 recites a signal indicat[ing] when the memory device is to begin
sampling write data, Rambus is hard pressed to argue that the delay value is
encompassed by the 914 patents start indicator, but not also encompassed by
the 109 patents signal.
Accordingly, Rambuss claim differentiation argument, even if considered,
fails.

e. The Board Did Not Improperly Rely on a Dictionary
Definition of the Term Signal
Finally, Rambus argues that the Board improperly began with the IEEE
dictionary definition of signal and essentially ignored the use of the term in the
specification, equating it with other generic terms such as code, data, and
value. Br. 38-39. This is a remarkable argument given the limited attention the
Board paid to the IEEE definition. See JA10, 14, 21. In any case, the Board did
not begin with a dictionary definition. Rather, the Board began by looking to the
language of the claims, then by making detailed findings regarding the use of the
term signal in the 109 patents specification, and then only referenced the
dictionary to show that the use of the term in the specification was consistent with
the meaning of the term in the art. Id. This Court has held, [w]hen the intrinsic
evidence is silent as to the plain meaning of a patent claim term, it is entirely
appropriate for the district court to look to dictionaries or other extrinsic sources
for context, and aid it in arriving at theplain meaning of a claim term.
Helmsderfer v. Bobrick Washroom Equip., Inc., 527 F.3d 1379, 1382 (Fed. Cir.
2008). It is equally appropriate for the Board to look at such an extrinsic source
when determining the meaning of a term.
For the first time on appeal, Rambus cites a lay dictionary, Websters Third
New Intl Dictionary 2401 (2002), to rebut the IEEE definition and to support its
narrow construction of signal as something that incites immediate action. Br.
Case: 12-1480 Document: 28 Page: 32 Filed: 11/29/2012
-
7/30/2019 109k
33/47
26
31; see also Br. 54 (citing Websters Third New Intl Dictionaryfor the term to).
This evidence was not before the Board and should not be raised here in the first
instance. In re Watts, 354 F.3d at 1367. However, even if one were to look at a
lay dictionary, one must consider other definitions it provides in the relevant
context of electrical engineering. Even the lay dictionaries recognize that signals
have a special meaning, i.e., an electronic impulse that transmits or conveys
information.8
As to Rambuss related argument that signal deserves a narrower
interpretation from other terms of claim 1 of the 109 patent, such as code,
data, and value, in light of the specification (Br. 21, 39-41), this is another
misreading of the Boards opinion. The Board did not equate signal with code,
data, and value, but it equated it with another term of art in the specification,
delay value. The Board found that a strobe signal and a delay value both
function as signals that indicate when a write operation is to take place.
In sum, Rambus has failed to demonstrate that the Board erred in its
construction of the term signal. The Board properly gave the claims their
8See, e.g., Merriam-Webster.com, http://www.merriam-webster.com/dictionary/ signal (last viewed Nov. 19. 2012) (a detectable physical quantity or

broadest reasonable interpretation consistent with the specification. In re Bond,
910 F.2d 831, 833 (Fed. Cir. 1990) (quotingIn re Sneed, 710 F.2d 1544, 1548
(Fed. Cir. 1983)).
3. Substantial Evidence Supports the Boards Finding that
Farmwald Anticipates Claims 1-25
The Boards anticipation findings are supported by substantial evidence and
should be affirmed. As the Board found, and the Examiner enumerated in his
answer, Farmwald discloses each claimed element of the 109 patent. JA10-21.
As to the first element of claim 1, providing control information to the
memory device, wherein the control information includes a first code which
specifies that a write operation be initiated in the memory device, the Board found
that Farmwald discloses a request packet that contains control data that in turn
includes control operations such as writing data. JA8. This finding is supported
by the express teachings of Farmwald, which explicitly provide control
information that tells the memory device that it will be storing (writing) data.
JA17605, col. 9, ll. 32-57 (. . . a request packet 22 contains 6 bytes of data . . . .
The first byte contains two 4 bit fields containing control information . . . . The
AccessType field specifies whether the requested operation is a read or a write . . .
.) (emphasis added).
As to the second element of claim 1, providing a signal to the memory
device, wherein the signal indicates when the memory device is to begin sampling
Case: 12-1480 Document: 28 Page: 34 Filed: 11/29/2012
-
7/30/2019 109k
35/47
28
write data, the Board found that Farmwald discloses a request packet that controls
the timing of writing data either by directly select[ing] a certain register in the
slave DRAM memory device which stores the (delay value) timing information or
indirectly by indicat[ing] pre-selected (delay value) access times. JA8 (citing
col. 9, 1. 46 to col. 10, l. 5). Again, this finding is based on Farmwalds explicit
disclosure of a delay time indicating to the memory device when it is to begin
storing (writing) data. JA17605, col. 9, ll. 18-30 (The data block transfer occurs
later at a time specified in the request packet control information . . . . The time
after which a data block is driven onto the bus lines is selected from values stored
in the slave access-time registers.).
Further, as the Board noted, Farmwalds claim 28 recites outputting a
value to the memory device, wherein the value is representative of the delay time;
and outputting a second operation to the memory device, wherein the second
operation code instructs the memory device to internally store the value. JA8;
JA17614 (claims 25 and 28). Farmwalds claim 28 further demonstrates how
Farmwalds delay value operates in the same manner as claim 1.

4. Rambuss Alleged Errors Regarding Anticipation
Have No Merit
a. Farmwalds Delay Value Is Not Used Before the
Write Operation
Rambus argues for a particular sequence of the steps in claim 1, that the
sequential nature of the claim steps that implement that method . . . is apparent
from the plain meaning of the claim language and its structure. Br. 26-27.
Rambus posits that with respect to the second and separate step of providing a
signal . . . .[,] [t]hat signal is distinct from the first code . . . and necessarily comes
after the first code. Br. 27. According to Rambus, Farmwald begins with
delay values and is different: it stores delay values that set the time for data
transfer relative to the devices receipt of the command control information. Br.
33.
As discussed, there is no requirement in the claim that the steps be
performed in a certain order. However, even if this were a requirement, substantial
evidence supports a finding that Farmwald provides a signal at least when the write
operation is requested, not before by statically storing a predetermined delay value.
Farmwald specifically says the slave device (e.g., a DRAM or memory
device) carries out requests sent by the master device (e.g., a CPU) at the
time requestedor specified by the master device:
The bus architecture of this invention connects master or bus
controller devices, such as CPUs, Direct Memory Access devices
Case: 12-1480 Document: 28 Page: 36 Filed: 11/29/2012
-
7/30/2019 109k
37/47
30
(DMAS) or Floating Point Units (FPUs), and slave devices, such as
DRAM, SRAM or ROM memory devices. A slave device responds to
control signals; a master sends control signals. . . .
* * *
All information sent between master devices and slave devices is sent
over the external bus . . . . This is accomplished by defining a protocol
whereby a master device, such as a microprocessor, seizes exclusive
control of the external bus (i.e., becomes the bus master) and initiates
a bus transaction by sending a request packet(a sequence of bytes
comprising address and control information) to one or more slave
devices on the bus. . . . The slave that the packet is directed to must
then begin any internal processes needed to carry out the requested
bus transactionat the requested time. The requesting mastermay alsoneed to transact certain internal processes before the bus transaction
begins.After a specified access time the slave(s) respond by returning
one or more bytes (8 bits) of data or by storing information made
available from the bus.
A17603-17604, col. 6, l. 19 to col. 7, l. 14. Therefore, the fact that certain delay
values are stored within the memory device, before an instruction (e.g., a write
operation) is sent, does not mean that the signal indicating when to begin the write
instruction is provided before the operation. When to do something is
determined by the master CPU, not by the DRAM or memory device, which is a
slave.
b. Farmwalds Delay Value is Flexible and Variable
Rambus argues that Farmwalds delay value system is inflexible and
therefore does not meet the limitations of claim 1. Br. 34-35. However, claim 1
does not recite or otherwise require flexibility or variability. Moreover, even
Case: 12-1480 Document: 28 Page: 37 Filed: 11/29/2012
-
7/30/2019 109k
38/47
31
if claim 1 of the 109 patent did require flexibility or variability, there is no
specific level of flexibility or variability required by the claim. Certainly, there is
no particular degree of flexibility or variability required by claim 1 that excludes
Farmwald.
In light of this, Rambus argues that the 109 specification expressly
distinguishes Farmwalds method as prior art. Id. This is simply incorrect. The
passage of the 109 specification cited by Rambus (JA58, col. 10, ll. 2539) is a
discussion of the prior art, it makes no mention of Farmwald, and is immediately
followed by a non-prior artdiscussion of an alternate embodiment of the 109
patents invention, which, as the Board found, mirrors Farmwald. JA58, 10:5267;
JA14-15.
Moreover, like the embodiments of the 109 patent, which are flexible
because, as stated, they can vary the amount of time (latency) between a request
packet and the corresponding data transmission, Farmwald allows the delay value
to be varied by the controller by providing multiple delay value choices. For
example, as the Board found, Farmwald demonstrates flexibility by sending a
request packet having a code for selecting different access-time registers each
storing a different delay value, by otherwise programming and storing different
values in such access-time registers, or by sending different operation codes
representing different delay values. JA16. This finding is supported by the

explicit language of Farmwald, which states: In a preferred implementation,
semiconductor devices connected to the bus contain registers . . . which store a set
of one or moredelay times at which the device can or should be available to send
or receive data. JA17603, col. 6, ll. 40-45; see also JA17603, col. 6, ll. 54-55
(Each slave may have one or several access-time registers (four in a preferred
embodiment).); JA17604, col. 7, ll. 12-14 (More than one access time can be
provided to allow different types of responses to occur at different times.).
Given that Farmwald teaches multiple delay value choices, Rambus
alternatively argues that Farmwald is relatively inflexible in comparison the 109
patent. Rambus bases this argument on two points: (1) Farmwald does not teach a
decoupled write instruction and delay value, and (2) Farmwald has a confined set
of delay value choices determined by a limited number of access-time registers and
operation codes. Br. 49.
In response to Rambuss first point, the Director has already demonstrated
that claim 1 simply does not require the type of decoupling defined by Rambus.
Regarding Rambuss second point, as stated above, nothing in the claim 1 of the
109 patent requires a particular degree of variability of signal times, let alone the
narrow conception of variability asserted by Rambus. Rather, the patent
distinguishes prior art that is totally inflexible, i.e., art where the delay time is
predetermined and dictated by the timing of the request for the data transfer.

JA58, col. 10, ll. 27-33. Here, Farmwalds ability to vary its delay time, shows
that it is not totally inflexible, and therefore it can fall within claim 1.
c. Substantial Evidence Supports the Boards Findings
That There are Four Ways that Farmwalds Delay
Value Can Function as a Signal
Rambus argues that the Board improperly advanced several unsupported
hypothetical delay value teachings of Farmwald to satisfy the providing a
signal step of claim 1. Br. 51. Contrary to Rambuss assertion, the Board did not
advance unsupported hypotheticals.
On page 12 of the Boards decision (JA13), the Board states that the delay
value itself can be found or accessed in four ways in Farmwald: in the request
packet, in the access-time register, when a comparison to the computer clock
happens, and/or when the delay value expires, i.e., the match of the expiration of
the delay value and the beginning of an operation. This should be uncontroversial
as a delay value is stored in an access-time register and then used by the master
and slave to determine when to initiate an operation.
On page 13 of the Boards decision (JA14), the Board specifically identifies
how Farmwald meets the providing a signal element of claim 1. The Board
found that skilled artisans reasonably would have considered . . . transmitting or
otherwise providing additional control information (i.e., additional to the first
code) within a request packet, such as the variable delay value signal as meeting

34
the providing a signal element of claim 1. JA14. In other words, the Board held
that Farmwald provides a signal when the master device tells the slave memory
device in the request packet when to begin an operation: The data block transfer
occurs at a later time specified in the request packet control information.
JA17605, col. 9, ll. 18-19 (emphasis added). As discussed above, it is the master
that requestsand specifies what the memory does, and thus, as the Board
finds, transmits the timing signal. This is not a hypothetical and is supported by
substantial evidence.
In addition to its principal findingand undoubtedly in response to
Rambuss numerous asserted possible limitations on the claimthe Board also
found that, [a]lternatively, skilled artisans would have considered either 1) storing
the delay value in the access register, 2) retrieving it, or 3) comparing it to a clock
value and generating another implicit signal, as Farmwald provides, as also
constituting providing a signal, as recited in claim 1. JA14. The Boards
enumerated options were not unsupported hypotheticals, but were discussed and
substantiated throughout the Boards decision. See, e.g., JA12-13, JA7-9 (Findings
of Fact); see alsoJA17528-17529 (Decision on Request for Rehearing). By
referring to four options, the Board is simply reiterating, as discussed throughout
its decision, that depending how one defines providing a signal (e.g., inciting
immediate action or sent separate and apart from the write command as

Rambus asserts) Farmwald meets those definitions. For example, Farmwalds
signal may be provided separately when it is programmed into the access time
register, separately when it is retrieved in response to a request packet, and/or
immediately when it is compared to the clock to determine that the delay time has
expired and that the write operation must commence. The Board cannot be
criticized for simply articulating how Farmwald meets the myriad possible
limitations that Rambus advances.
d. Farmwalds Signal Originates from Outside theMemory Device
Finally, Rambuss argues that claim 1 requires that the signal originate from
outside the memory device and that Farmwalds signal, as found by the Board,
allegedly does not. Br. 55-56. Again, Rambus attempts to read limitations from
the specific embodiments in the specification into the claims. But claim 1 does not
require that the signal originate from outside the memory device. It simply says
that the claimed signal is provided to the memory device. Thus, it is reasonable
to interpret the signal as being provided from outside the memory device or as
simply being provided from one component of the memory device to another.9
Indeed, Farmwald discloses both options.
9Rambus cites Semitool, Inc. v Dynamic Micro Sys. Semiconductor Equip. GMBH,
444 F.3d 1337, 1348 (Fed. Cir. 2006) for the proposition that if the claimed
signal is provided to the memory device, it must originate from outside the entirememory device. Br. 54. Semitool is distinguishable based on specific facts

36
In Farmwald, the signal can come from outside the memory device by being
included in the request packet sent by the master device to the memory device:
The data block transfer occurs at a later timespecified in the request packet
control information. JA17605, col. 9, ll. 18-19 (emphasis added); see also
JA17604, col. 7, ll. 5-7 (The slave that the packet is directed to must then begin
any internal processes needed to carry out the requested bus transaction at the
requested time.) (emphasis added). The master device requests the time value,
then sends the request packet with the timing information to the memory device.
Indeed, it is the master device (located outside the memory device) that generally
controls all actions of the slave memory device. See, e.g., JA17603, col. 6, ll. 19-
24 (The bus architecture of this invention connects master or bus controller
devices, such as CPUs, Direct Memory Access devices (DMAS) or Floating Point
Units (FPUs), and slave devices, such as DRAM, SRAM or ROM memory
devices.A slave device responds to control signals; a master sends control
signals.).
Alternatively, the choice of the delay value can be determined by the
memory device itself. This approach is demonstrated by a discussion in Farmwald
relating to the architecture of a semiconductor wafer carrier cleaning system that
required an outside supply of drying gas to a process chamber. Semitool cannot
support a more general proposition that whenever a claim term says something is
provided to a device, be it a machine, hardware, or a software device, that theitem provided must originate from outside the device.

37
that sets out both a direct (outside) option and an indirect (inside) option: The
choice of access-time register can be selected directly by having a certain op code
select that register, or indirectly by having a slave respond to selected op codes
with pre-selected access times (see table below). JA17605, col. 9, l. 66 to col. 10,
l. 3 (emphasis added). Thus, whether the claimed signal originates from outside
the memory device, as Rambus asserts, or inside the memory device, Farmwald
meets the limitation.
In sum, substantial evidence supports the Boards findings that Farmwald
provides the claimed signal, and therefore that claim 1 is anticipated.
