The PTAB is not often persuaded by objective evidence of non-obviousness, i.e., secondary considerations, when the scope and content of the prior art includes all of the features recited in the claims. However, a pair of recent PTAB decisions, Innopharma Licensing, Inc. v. Senju Pharmaceutical Co., LTD., IPR2015-00902, Paper 90, and IPR2015-00903, Paper 82 (PTAB July 28, 2016), provides a rare example where the PTAB completely changed its mind after instituting the IPRs. The decisions offer the same message, and this post focuses on the decision in IPR2015-00902, where the PTAB found all of the challenged claims of U.S. Patent No. 8,669,290 not obvious over the applied prior art references based on the objective evidence of non-obviousness.

As we’ve previously reported, patent owners have had little success arguing secondary considerations of non-obviousness during inter partes review. Underscoring the challenge that patent owners face, the Federal Circuit recently affirmed a PTAB obviousness determination despite finding that it had erred in its consideration of the patent owner’s evidence regarding objective indicia of non-obviousness.

Evidence Dice Representing Evidential Substantiation and Proof

In Merck & CIE v. Gnosis S.P.A., Gnosis Bioresearch S.A., Gnosis U.S.A. Inc., Case No. 2014-1779 (Fed. Cir. Dec. 17, 2015), the Federal Circuit affirmed the Board’s decision that the contested claims were invalid for obviousness, determining that the Board’s factual findings were supported by substantial evidence, and agreeing with the Board’s conclusion of obviousness.  However, in dissent, Judge Newman asserted that the Federal Circuit’s substantial evidence standard of review for the Board’s factual findings in AIA trial decisions is not appropriate under the AIA, and that based on a review without deference, the Board’s decision in this case should be reversed.

Success PuzzleIn what appears to be only the second instance¹ to date, evidence of secondary considerations helped a Patent Owner defend against a Petitioner’s obviousness challenge during an IPR proceeding.  In Phigenix, Inc. v. Immunogen, Inc., the Board issued its final written decision and held that each of the eight challenged claims were not unpatentable, finding the Patent Owner “advances persuasive evidence” regarding the prior failure of others and the long-felt need in the industry. Phigenix, Inc. v. Immunogen, Inc., IPR2014-00676, Paper 39, (“Dec.”) (PTAB Oct. 27, 2015).

DetailsBoehringer Ingelheim filed three petitions attacking patents generally drawn to methods of treating RA patients with rituximab.  The decisions on two of those petitions, i.e., IPR2015-00415 and IPR2015-00417, have been addressed elsewhere.  In IPR2015-00418, the PTAB declined to institute an IPR on the petition’s challenges to the lone claim of U.S. Patent No. 8,329,172, drawn to a method of treating low-grade non-Hodgkins lymphoma (LG-NHL) with CVP tri-chemical chemotherapy and rituximab maintenance therapy.

Filed concurrently with the petitions at issue in IPR2015-00417 and IPR2015-00418, Boehringer Ingelheim filed the petition at issue in IPR2015-00415 seeking review of U.S. Patent No. 7,820,161 owned by Genentech and Biogen Idec.  The Board’s institution decision steadily whittled down Boehringer’s varied attacks on the patent.  Ultimately, IPR was granted on 2 of the 36 obviousness grounds in the petition (additional grounds were summarily denied for failure to identify the ground with particularity), with the two surviving grounds implicating half of the 12 claims of the ‘161 patent.
