CLAIM PRIOR ART DISCLOSURE
“bispecific antisense oligodeoxynucleotide” . . . “of sufficient length to act as an antisense inhibitor” of IGFBP-2 and IGFBP-5”[claims now limited to [surprisingly] most active 20-mer) & modified forms]
●List of all 15-nucleotide sense oligos (>1400)●States antisense oligos can interact with sense oligos, 15-mer to 25-mer, bispecific● Knowledge of how to make oligos●No understanding of which targets would be useful

SCOPE: ENEMY OF TERMHELD NOT PATENTABLE (35 U.S.C. § 102)

CLAIM PRIOR ART DISCLOSURE
“An isolated polypeptide comprising the amino acid sequence of SEQ ID NO:1.”
●DNA sequence in an article annotating a mouse cDNA library + disclosure of corresponding protein sequence (w/o isolation of the protein)●Reiterates prior art need not disclose use or utility
In re Chuang (Bd.)
●[ w w w . d u a n e m o r r i s . c o m ]
SCOPE: ENEMY OF TERM HELD NOT PATENTABLE (35 U.S.C. § 103)

CLAIM PRIOR ART DISCLOSURE
“isolated nucleic acid molecule . . . encoding a polypeptide at least 80% identical to amino acids 22-221 of SEQ ID NO:2 . . .”
Specification referred to same treatise mentioned in prophetic example
[qualify when conventional methods used]
Obvious to try + reasonable expectation of success applied to less predictable
art
1st reference:●Monoclonal AB to “p38” [commercially available]●Prophetic disclosure of conventional methods (citing treatise) for use in obtaining p38 cDNA●No p38 isolation or protein sequence
2nd ref: cloned mouse analog
In re Kubin

CLAIM LACK OF WRITTEN DESCRIPTION
A method for . . . “reducing NF-κB activity” comprising “reducing binding of NF-κB to NF-κB recognition sites on genes which are transcriptionally regulated by NF-κB.”
Single step method did not refer to molecules in a class exemplified by representative species
•Specification referred generally to 3 classes of molecules covered by claim that would decrease activity, only one of which was arguably described
•No working or prophetic examples of molecules reducing NF-κB activity; no completed syntheses of any molecules prophesized to have activity
•State of the art was “primitive and uncertain” so couldn’t fill the holes in disclosure. [See also, In re Alonso]
Ariad v Eli Lilly
●[ w w w . d u a n e m o r r i s . c o m ]
SCOPE: ENEMY OF TERM: 35 U.S.C. § 112

CLAIM LACK OF WRITTEN DESCRIPTION
Claims to needleless connector valves comprising a body and a seal;
claims omitted “spike” limitation present in all disclosed embodiments
Draft embodiments with and without elements
No description of “spikeless” valves covered by claims which do not recite a “spike” element.
ICU Medical v. Alaris
●[ w w w . d u a n e m o r r i s . c o m ]
SCOPE: ENEMY OF TERM
AVOID LATE-DISCOVERED ART● Do search & diligence early to avoid supplemental
filings or RCE that decrease PTA● E.g., Inventor publications; rejections in related
cases● Meeting notes from inventors & employee co-
workers of inventor? (Monsanto v Bayer)● Details of testing to distinguish prior art
(Aventis v Amphastar)● Filing RCE eliminates Type B (Post 3-year) PTA
