Executive Summary

IEEE engaged 1790 Analytics in this project to assess the impact of IEEE publications on

developments in various technologies. This impact is measured by examining the extent

to which patented inventions build upon papers from IEEE journals, IEEE-sponsored

conferences, and IEEE standards. This is an update of previous reports, and examines

patents issued from January 1, 1997 through December 31, 2013.

The main findings of this report are:

New technology continues to build upon science, and the dependence is increasing.

When we did a similar study last year, we found that the top 40 companies were

granted 92,152 patents in 2012. These patents made a total of 371,910 non-patent

references, an average of 4.04 non-patent references per patent. In this study, the

top 40 firms were granted 70,839 patents, which patents made a total of 386,215

non-patent references (an average of 5.45 non-patent references per patent). Thus,

we continue to see the number of non-patent references trending upward. Since a

large number of these non-patent references are to scientific articles and conference

papers, this suggests that today’s technology developments are increasingly linked

to developments in published science.

A large portion of this science base comes from papers presented at IEEE sponsored

conferences and published in IEEE journals. The top 40 patenting firms in 2013

have referenced over 961,385 articles in the last 17 years. About 31% (300,280) of

those articles appeared in IEEE journals or IEEE sponsored conferences.

In this study, we also went beyond the top 40 patenting companies and analyzed all

patents from the last 17 years in several technology categories of interest to IEEE

members and customers. For example, approximately 35% of all scientific

references from Computer Hardware patents go to IEEE publications. The second

most referenced publisher is ACM (Association for Computer Machinery) with 17

% of the referenced publications. In other Information Technology areas, such as

Information Storage, Semiconductor Manufacturing, and Computer Software, the

results are similar.

In Telecommunications technology, IEEE is particularly important. The 302,000+

references to IEEE articles and conferences represent almost half of all science

references from Telecommunications patents since 1997. To help put this in

perspective consider: Telecommunications is a very technology driven industry and

that technology is often built upon scientific discoveries published in journal and

conference papers. If we consider this set of papers as the science base of

telecommunications, than roughly half of that science base is published in IEEE

journals or presented at IEEE sponsored conferences. In addition, the 302,000+

references to IEEE dwarf the combined total of the next 25 publishing organizations

in this technology.

ii

IEEE is referenced a surprising amount in areas which are not central to its mission.

For example, almost 7% of the science references from patents in medical

devices go to IEEE publications. This ranks IEEE third behind Elsevier and

Lippincott (with 24% and 11% respectively). The latter publishers have 400+

and 100+ journals in the medical area, whereas IEEE has only a few, so the 7%

figure is quite solid for a non-core area.

Optics is also somewhat surprising. IEEE publications receive the most

references from Optics patents, and IEEE is referenced significantly more than

the two large Optics Societies that would be expected to lead the area: OSA –

The Optical Society of America, and SPIE – The International Society of

Optical Engineering.

Another non-Information Technology Area in which IEEE does very well is

Clocks & Timepieces. About 42% of all references from clock related patents

reference articles from IEEE. No other organization receives more than 6% of

the references from patents in this category.

In Measuring, Testing, and Control, IEEE gets 19% of all references, which is

just ahead of Elsevier’s 14.6% while, again, Elsevier has many more journal

titles in the space.

In the Nuclear, X-Ray, and Radiant Energy category IEEE is referenced fourth

most often behind Elsevier, The American Chemical Society, and The American

Institute of Physics. This is not terribly surprising since a large number of

patents in this space are related to Nuclear Medicine where Elsevier has journal

titles but IEEE has none.

In the Robotics and Intelligent Manufacturing category, 43% of the patent

references are to articles published in IEEE journals or in proceedings of IEEE

sponsored conferences. Second place Elsevier receives only about one-fifth as

many references in the category.

Patents related to Power Systems and Transmission also reference IEEE

publications most frequently. The nearly 17,000 references to IEEE journal and

proceedings papers are more than the next two top referenced publishers

(Elsevier and Electrochemical Society) combined. We also examined a

specialized subset of the Power Transmission category related to smart meters

and smart grids. In this category, a full 64% of the scientific references from

patents go to IEEE journal or conference papers. The second most referenced

publisher is ACM with only 3.5% of all references.

Two new categories were added this year: Solar and Photovoltaic energy and

Wind energy. In the latter category IEEE science has a big advantage over the

iii

other publishers with more than 45% of the references. In solar energy, Elsevier

leads with IEEE in second place. The Elsevier lead is not surprising since it has

more than 50 journal titles related to the area including several high impact

journals such as Solar Energy Materials and Solar Cells, Thin Solid Films, Solar

Energy, Synthetic Metals, Journal of Crystal Growth, and Solar Cells.

It has been shown that high-quality, high-impact, and valuable patents tend to be

cited more frequently by later patents. Citation impact is thus often used as a

quantitative measure for evaluating patents (see [3]). In this study, we found that

the patents that reference IEEE papers are cited more often than patents that do not.

This was shown to be true for each of the fifteen technology categories we

examined. This suggests that, not only do IEEE publications frequently provide the

science base for new inventions, but that inventions that build upon IEEE

publications are more likely to be valuable in the future than inventions that do not

build upon IEEE.

Although this study concentrates on patents in specific technology areas, it should

be noted that the importance of scientific and technical literature to patented

technology is increasing in all areas. Our research shows that the average US patent

had only 2.76 non-patent references (NPRs) back in 1997. That number jumped to

10.08 by 2013 – a 265% increase. During those same periods, the number of

references per patent to IEEE has increased by 240%. In terms of total references,

NPRs to IEEE published papers have increased 768% compared with 1997. Again,

these numbers are for all issued US patents and not just those in the fifteen

categories covered in this report.1 This means that in the overall patent system,

patented technologies are increasingly referencing scientific articles and that IEEE

provides an increasing portion of that science base.

1 Including science intensive areas like Biotechnology, Pharmaceuticals, Chemicals, and other areas where

IEEE typically has little influence.

I. Introduction

In previous studies, it was found that patents reference papers from IEEE journals much more

often than papers from other journal publishers. In this report, we update the previous results,

and study US patents issued from January 1997 through December 2013. Although this report is

an update of previous results, we have made our best efforts to make this report self-contained.

The aim of this report, as in previous reports, is to analyze references from patents to journal

articles, conferences and standards documents, in order to assess IEEE’s impact upon

technological developments.

This report covers 15 subcategories of Technology where IEEE members and readers are active.

Many, but not all are related to Information Technology. The categories (including two new

categories related to solar and wind), with patent counts are shown below in Table 1.

II. Methodology

This study is based on referencing patterns from patents to prior art documents. When an

inventor files a patent for a new invention, he/she will typically reference earlier documents to

show that the new invention either builds upon, or improves upon, what came earlier. The

inventor’s patent attorney and/or the examiner may also add prior art references to either clarify

or limit the claims of the new invention.

As an example, Figure 1 shows the front page of a General Electric patent. The prior art

references on this patent come in two forms - references to earlier patents, and “other

references”. These other references are often to scientific publications, such as those produced by

IEEE. In this report we are primarily concerned with these other references, which are also

sometimes called “Non-Patent References”.

It has been suggested that patents with many non-patent references are likely to contain new

leading-edge ideas, whereas patents that only reference earlier patents are likely to be

incremental improvements on earlier patented technologies. For a comprehensive study on

various hypotheses surrounding the motivations of inventors in citing other references, see [1].

Patent Sets used in the Analysis

This study is based on two patent sets. Our analysis is based on determining the number of

references from these patent sets to publications from publishers such as IEEE, Elsevier, the

American Institute of Physics, and others.

The first set contains patents from the top 40 patenting companies in 2013. Analysis of this

patent set provides an insight into how the top tier companies rely upon science from IEEE and

other publishers. The second set contains all patents in fifteen technology categories from all

companies, universities, government agencies, and individuals. The fifteen technology categories

examined are shown in Table 1 above. Analysis of this patent set reveals the wider influence of

IEEE science in these technologies.

Identifying Relevant Non-Patent References

Non-patent references can be to any published document, from comic strips and brochures, to

scientific articles and standards documents. The main difficulty in identifying relevant non-

patent references for a study such as this is that inventors do not use a standard form for listing

references. As an example, Table 2 contains eight different variants for the IEEE Global

Telecom Conference. Note that some inventors just use the GLOBECOM shorthand, while

others list the entire name. Sometimes IEEE is mentioned and sometimes it is not. When

abbreviation variations are included such as Telecom, Tele, Tcom, Proc., Proceed., the number

of variants increases further. The same issue exists for variants in journal names and standards

documents. For example there are more than 30 variant spellings of the journal title Journal Of

Thoracic And Cardiovascular Surgery including numerous mis-spellings of thoracic and every

conceivable way of abbreviating cardiovascular.

Conference Identification – to identify conference proceedings among the non-patent

references, we first identified references containing keywords such as meeting, symposia,

conference, etc. We then used parsing software to identify 2-word and 3-word phrases that

appear frequently in this set of papers. The full string was identified for these string sub-

sequences in order to identify frequently cited conferences. In this way, we identified the top

conferences referenced in the patent sets, and standardized the names of these conferences (i.e.

all of the different variants of a conference were collected under a single name). As an example,

all of the variants shown in Table 2 are assigned to the name ‘<conf> IEEE Global

Telecommunications Conference (GLOBECOM)’.

We then looked up each of these conferences on the web to determine who is listed as their

primary sponsor. For example, many of the conferences are sponsored by organizations such as

IEEE, ACM (Association for Computer Machinery) and ASME (American Society of

Mechanical Engineers). Some conferences are jointly sponsored by multiple organizations and

this is noted as well.

When we first started identifying conferences in the 2005 report, we looked up the top 100 most

referenced conferences in order to identify the primary sponsors or hosts. In this current report

we have identified the sponsors for the top 1,000+ most referenced conferences. These 1,000+

conferences are listed under more than 12,000 variant names.

Standards Identification – Standards documents are increasingly referenced, and in general they

are easy to identify by looking for strings such as ‘standard’ or ‘std’. Once the records containing

the standards were located, it was relatively easy to identify the organization that produced each

standard (ITU, IEEE, ISO, JEDEC, ANSI, etc.). Further, once the standards bodies are

identified, we then identify references to other documents that do not specifically list the words

‘standard’ or ‘std.’ The latter step is necessary since some references look like this

“ISO/TC97/SC21/N2066” or “IEEE802.3” without a specific mention of the word “standard.”

As a consequence we also identify other non-standard documents released from these

organizations including draft standards and “requests for comments” documents.

Journal Identification – identifying and standardizing journal names is a very difficult process

because there are so many different journals, and their names can be abbreviated in many

different ways. To make the problem more manageable, we base our analysis primarily to the

16,000+ journals covered by the ISI/Thomson Scientific Database. This is not a severe

limitation, since these 16,000+ journals include more than 100 IEEE journals, 1400+ Elsevier

journals, and 350+ Wiley journals. In addition, we also identify publishers of about 1,000 non-

ISI journals if they appear very frequently in the patent references, but do not appear in the ISI

database.

Once restricted to these 17,000+ journals, we used software that transforms journal names into

common abbreviations and then implements string matching. Care must be taken with string

matching because, for example, searching for “Urology Journal” will also accidentally identify

“Neurology Journal”. Similarly, a search for the journal “Science” would accidentally pick up

any reference with ‘science’ in the paper title as well as any of the 800+ journals with science in

their titles such as “Game and Wildlife Science”. Our proprietary software for journal

identification deals with all of these problems along with some human intervention, so that we

generate an accurate match between the patent references and 17,000+ journals. After

identifying all of the relevant journals, we then used the ISI database and web research to

identify the publisher of each journal

III. Results

References from Top 40 Patenting Organizations

Table 3 shows the 40 firms that were granted the largest number of US patents in 2013. It should

be noted that many of these firms consist of multiple subsidiaries, and these firms patent under

many names. (For example General Electric has patents filed under 316 names, of which only a

fraction contain General Electric in the name.) We identified all of the subsidiary names for each

company to ensure that our patent counts are accurate.

We identified the top 40 patenting firms because we want to understand the extent to which the

current technology leaders use IEEE science. Figure 2 shows the 20 publishers of science whose

publications are referenced most frequently by the 40 firms shown in Table 3. This figure shows

that patents issued to the top 40 firms between 1997 and 2013 reference IEEE papers,

conferences, and standards more than 300,000 times. This is more than three times as many

references as the second placed publisher (Elsevier). In addition, if conference publications that

are jointly sponsored are counted, such as the conferences jointly sponsored between IEEE and

the Japanese Society of Applied Physics, or IEEE and ACM, then the number of references from

the top 40 companies to IEEE increases by another 20,000 references.

IEEE receives about 31% of the science references from the patents of the top 40 companies.

The next closest publisher (Elsevier) has 8.5% of the total and IEEE’s share of references is

about the same as the next 8 publishers combined. About 1/3 of the 300,000+ patent references

to IEEE are to IEEE sponsored conferences.

Table 4 illustrates the reference distribution of IBM, which is the top patent holder in 2013 (and

for the past 15 years). This reference distribution is typical of the top 40 firms. The references

from IBM to IEEE are actually to a number of different IEEE journals and conferences. In this

table, IEEE journals are highlighted in yellow and IEEE conferences are highlighted in orange.

The top overall reference is to IEEE is to the International Electron Device Meeting. The top

IEEE journals are IEEE Computer Magazine and IEEE Transactions on Electron Devices.

Notice that a full 26 of the top 50 journals and conferences referenced by IBM patents are

published or sponsored by IEEE. Ten of the top 50 journals and conferences are published or

sponsored by ACM. As a software firm, IBM tends to reference ACM much more than most of

the top 40 firms, but still IBM references IEEE almost twice as often as ACM as seen in

Appendix A (32,396 total references to IEEE from IBM versus 16,729 references to ACM). The

reader may notice the large number of references to ‘IEEE Unseparated’ or ‘Misc ACM.’ These

are articles that reference IEEE or ACM, but the inventor has not given a reference specific

enough to identify the proper journal or conference. A few examples can be found in Table 5

below. These are relatively complete references; it is not clear why the inventors were not more

careful about listing the full journal names.

References from Companies in Fifteen Technology Categories

In the previous section, we analyzed the use of IEEE science by the top patenting organizations.

Out of all science publishers, IEEE was cited most often by these organizations by a wide

margin. However, looking only at the top companies tells an incomplete story. IEEE publishes

journals and runs conferences mainly in information technology, electronic and other areas. It is

therefore useful to examine the extent to which IEEE science is referenced by all organizations

that patent in specific technologies and not just the leading companies.

As mentioned in the methodology section, we identified all patents in the fifteen technology

categories shown above in Table 1. 1790 Analytics has developed a classification scheme that

categorizes all patents into 50 broad technology areas, and this scheme was used to identify all

relevant patents for this part of the analysis.

We examined each of the fifteen technology areas separately, and the results are summarized in

Figures 3-15. The first category shown (in Figure 3) is Clocks, Watches, and Timepieces. We

identified all non-patent references on patents related to this technology issued between 1997 and

2013. We then determined the science publishers responsible for the largest number of these

non-patent references. Figure 3 shows the result of this analysis, namely that IEEE science is

referenced far more by clock and watch related patents than science from any other publisher.

Forty two percent of all science references from these patents go to IEEE journal papers or IEEE

sponsored conference papers (the graphs also include standards documents, but the vast majority

of the references are to journal or conference papers).

Figures 4 and 5 are analogous to Figure 3 except they show referencing patterns from Computer

Hardware and Software patents. Here IEEE once again receives far more references than the

other publishers. In both cases, ACM is the second most referenced publisher, but it receives

about half of the references that papers published by IEEE receive.

Figure 6 examines the top referenced publishers in the Medical Device field, which covers

devices as well as diagnostic tools and surgical instruments. Here, IEEE is a respectable third in

an area that is somewhat outside its core competency. When we first started covering this

category in our 2005 report, the top publisher in this area was Lippincott Williams and Wilkins,

which publishes more than 100 health and diagnostic related journals, including Circulation,

Neurosurgery, Investigative Radiology, Anesthesiology, and Annals of Surgery. In recent years

Lippincott had been surpassed by Elsevier, which has more than 400 journals in the field, such as

Annals of Thoracic Surgery, and the Journal of the American College of Cardiology. In this

report, we see that Elsevier’s lead in references has further increased so that Lippincott now has

less than half as many references as Elsevier in the category.

The huge increase in references to Elsevier in this (and other) categories is due to several factors.

First, the number of science references in the medical field is much higher for recent patents than

for older patents, so a leading publisher in 2006 is likely to have a larger lead in 2011. Secondly,

Elsevier has been rather acquisitive in recent years and continues to acquire other publishers.

Finally, Elsevier has many journal titles, so that as ISI/Thomson has increased the number of

journals it covers in its database, Elsevier has benefited the most. Moreover, 1790 has increased

the number of journals identified outside of the ISI set, which also benefits Elsevier.

Figure 7 shows the results for the information storage category. In this area, IEEE is particularly

dominant. Almost half (44.6%) of all of the science references from patents in information

storage are to papers in IEEE journals or conferences. IEEE’s 53,791 references in this category

are about 6 times as many as second place AIP.

Figure 8 contains the results of patents covering Measuring, Testing, and Control technology.

Patents in this category are related to measuring or testing, force, pressure, weight, etc. as well as

chemically measuring substances (e.g. measuring CO2 levels). The category also contains

control devices since these technologies are often combined. For example a patent might be

related to a valve that adjusts at a certain pressure or at a certain pollution level. Since this type

of measuring can be done both mechanically, magnetically, electrically, or chemically, it is not

too surprising to see both IEEE and Elsevier and the Optical and Chemical Societies all near the

top of Figure 8. IEEE receives the most references, but the lead is not as dominant as in the

Information Technology related technology areas.

Figure 9 contains reference counts for Nuclear and X-Ray technology patents. Much of the

patenting in this category is related to Nuclear Medicine so it is not surprising that the top

referenced publisher is Elsevier. IEEE is fourth in referencing in this category behind the

American Chemical Society and the American Institute of Physics.

The results for the Optics category can be found in Figure 10. This is another area that is slightly

outside the IEEE core. IEEE still has a substantial lead over the second and third place publishers

the Optical Society of America (OSA) and the International Society of Optical Engineering

(SPIE). Since these latter two societies are Optical societies, it would be reasonable to assume

that one of these societies would lead in the category but IEEE strong journals and conferences

in the area receive more references from optics patents.

Figure 11 contains results for the patents related to power generation and transmission.

Although this is a non-information technology category, IEEE leads in references in this

category as well. 34% of science references from patents in this category go to IEEE

publications.

Intelligent Manufacturing and Robotics contains patents related to robotics, and robotics and

control systems related to manufacturing. According to Markets and Markets, the Robotics

market is expected to reach $21 billion in 2014 as a result of a population explosion in “service

robots” that mow lawns, vacuum floors, and manufacture things.

As this industry grows, new innovations will be patented, and from Figure 12 it looks like those

innovations will build upon ideas published in IEEE journal articles or presented at IEEE

conferences. We see in Figure 12 that 43% of all science references from patents in this space

refer to IEEE published articles. Elsevier is the second ranked publisher, but its papers receive

only 8.6% of the science references. In this category, IEEE has more references then the next 15

publishers combined.

Figure 13 shows that IEEE is also very strong in the Semiconductor category. Here, the inclusion

of conferences gives IEEE a substantial boost. Approximately one-third of the references to

IEEE are to conference papers. With conferences excluded, IEEE would be just slightly ahead

of the American Institute of Physics in terms of science references from semiconductor patents.

The Smart Meter/Smart Grid category covers patents related to improving the power grid as well

as for advanced residential electric meters. This is a relatively small category but as we see in

Figure 14, the IEEE provides the bulk of the science base with 64% of all patent references.

Solar and Photovoltaic energy results are contained in Figure 15. This is a new category this

year and is led by Elsevier. Elsevier has several strong journals in this category including Solar

Energy Materials and Solar Cells, Thin Solid Films, Solar Energy, Synthetic Metals, Journal of

Crystal Growth, Solar Cells, plus more than 50 smaller journal titles related to this technology.

The references to IEEE science in this category mainly go to the IEEE Photovoltaic Specialists

conference, the IEEE World conference on Photovoltaic Energy Conversion, and IEEE

Transactions on Electronic Devices.

The Telecommunications category is the strongest large category for IEEE. There are over 7

times as many references to IEEE conference and journal papers as to second place publisher

3GPP (which is a standards body). Standards are referenced more frequently in

telecommunications, but still not nearly as often as journal and conference papers. About 56% of

the 600,000 total references to all publishers are to journal articles; 25% of the references are to

conference papers, and about 19% are to standards documents. In terms of standards documents,

the 3GPP General Partnership Project, Internet Engineering Task Force and International

Telecommunication Union received the most references in the category. New

telecommunications patents are referencing scientific articles to a larger extent than in the past.

In this category in 2008 there were just over 118,000 references to IEEE and last year there were

257,000 references to IEEE papers. Now as we see in Figure 15, there are more than 302,000

references to IEEE for telecommunications patents from 1997-2013. Thus just one more year of

patents added more than 45,000 references to IEEE papers.

Standards documents are referenced increasingly often in Telecommunications patents. Four of

the top 12 referenced publishers are standards bodies. Moreover of the 302,000 references to

IEEE, over 17,000 are to various IEEE standards (mostly to the IEEE 802 family of standards).

Another new category is shown in Figure 17. This chart shows that 45% of all science

references from Wind Energy patents go to IEEE journal and conference papers.

Figures 3-7 show aggregate counts of references from all patents in each technology category.

Readers who wish to see the firms that reference IEEE publications in each category can consult

Appendix B. This appendix contains the 100 organizations that reference IEEE most frequently

in each category. Appendix C is similar, except that it contains the organizations that reference

IEEE most frequently in the fifteen technology categories combined.

Citation Index for Patents Referencing IEEE

In an earlier study (see [2]) it was shown that patents that reference specific IEEE journals

perform better on a number of quality metrics. Moreover, it was shown that the results were

statistically significant. In this report, we update a key figure from the previous study showing

the citation index of patents that reference IEEE papers versus peer patents that do not reference

IEEE.

The citation index is a normalized citation metric that takes the number of citations received by a

particular set of patents, and divides it by the expected number of citations for patents of the

same age and technology class. A random set of patents therefore should have a citation index of

1.0. Research has shown that patents cited by many later patents tend to contain important ideas

upon which the later patents are building (see [3] and [6]). Citation indicators are also the basis

for the patented financial models (see [4] and [7]) invented by the two 1790 founders Breitzman

and Thomas.

Figure 18 contains the Citation Index for the patents in the fifteen technology categories that

reference IEEE papers and conferences. Also shown is the Citation Index for the set of the

remaining patents in each category that do not reference IEEE. Note that the set of all patents in

each category should have a citation index near 1.0. Thus we see that the patents that reference

IEEE are cited 21% to 116% more than expected, while the patents that do not reference IEEE

are cited up to 14% less often than expected. This of course does not imply that all patents that

reference IEEE are likely to be more valuable than patents that do not reference IEEE, but it does

suggest that in general, patented technologies that build upon IEEE published or sponsored

science are more likely to be valuable than patented technologies that do not reference IEEE

science.

IV. Conclusions

When a patent is filed, it must reference the prior art upon which it builds, as well as any prior art

that limits the claims of the new invention. This study and prior studies show that science

published by IEEE forms a significant portion of this prior art for new patents.

In this study, we examined two separate patent sets. The first patent set consisted of patents

granted between 1997 and 2013 to the 40 organizations with the largest number of US patents

granted in 2013. The second patent set consisted of all US patents granted between 1997 and

2013 patents in fifteen key technologies: clocks, computer hardware, software, nuclear/x-ray,

robotics, semiconductors, solar energy, wind energy, measuring and testing, medical devices,

telecommunications, optics, power systems, and information storage. In both of these patent

sets, IEEE is the dominant source of non-patent prior art. In other words, IEEE journals and

conferences are key outlets for scientific discoveries relevant to cutting edge technology.

Finally, we conducted an analysis of citation indices for IEEE related patents and non-IEEE

related patents. These types of metrics have been shown in validation studies to be good markers

for the quality, impact, and potential value of patents [3]. In this study, it was shown that patents

that build upon IEEE published science tend to have higher citation indices than patents that do

not reference IEEE. This suggests but does not guarantee that patents that build upon IEEE

science are more likely to become high-quality, high-impact, valuable inventions than patents

that do not build upon IEEE.

Specific key results are identified in the Executive Summary.

Venkataramani , et al. January 7, 1997

Piezoelectric composite with anisotropic 3-3 connectivity

Abstract

A piezoelectric or electrostrictive composite exhibiting anisotropic 3-3 connectivity with a dense ceramic phase

and an infiltrate polymer phase. The ceramic phase is an interconnected ceramic lamelli structure that is

arranged substantially parallel in one direction. The ceramic lamelli have greater connectivity in the z direction

than in the x and y directions, while the connectivity in the x and y directions are essentially equal.
