In Dell, Inc. v. Acceleron, LLC, Case No. 2015-1513, -1514 (Fed. Cir. 2016), the Federal Circuit vacated in part the PTAB’s final written decision in IPR2013-00440, on the basis that the PTAB improperly canceled a claim based on a factual assertion first raised by the petitioner at final hearing, too late for the patent owner to meaningfully respond.

In its seventh PGR institution, the PTAB recently decided for the first time that a patent asserting a pre-AIA effective filing date was eligible for post-grant review because it contained at least one claim that was only entitled to a post-AIA effective filing date. Although some claims were entitled to a pre-AIA effective filing date, PGR was instituted for all of the patent claims, on all five of the prior art grounds asserted by the petitioner.

Final written decisions, IPR2014-00781, IPR2014-01086, IPR2014-00821, IPR2004-00580, IPR2014-00802, for IPRs of several patents owned by Zond, LLC, which include rare dissenting opinions, illustrate different views of APJs concerning the requirements for establishing that a reference is a printed publication under 35 U.S.C. § 102(b). These decisions provide helpful guidance on how to address references whose status as a printed publication may be in dispute.

When an alleged prior-art patent in an IPR claims priority to a provisional application, and the challenged patent claims priority to an intervening date between the provisional filing date and the non-provisional filing date of the reference patent, the burden is on the Petitioner to prove that the prior-
art patent is entitled to the filing date of its provisional application—by demonstrating that the claims of the reference patent are supported by the provisional application.

Boehringer 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.

Boehringer Ingelheim filed the petition at issue in IPR2015-00417 concurrently with the petitions at issue in IPR2015-00415 and IPR2015-00418 to challenge patents protecting methodologies for treating rheumatoid arthritis (RA) with rituximab, an FDA-approved antibody for treating certain cancers. The IPR2015-00417 petition specifically challenged the fourteen claims of U.S. Patent No. 7,976,838, which are drawn to methods of administering rituximab to RA patients not responding to TNF-α inhibitors, a subset of RA patients. The PTAB instituted an IPR of two of the 19 obviousness grounds contained in the petition. Given the number, and nature, of grounds to be reviewed, and the outcome, it is apparent that the more grounds found in a petition, the greater the chance that the best arguments will be lost in the shuffle.

The PTAB’s final written decision in Butamax Advanced Biofuels LLC v. Gevo, Inc. Case IPR2013-00539, Paper 33 (P.T.A.B. 2015), illustrates the importance of providing more than attorney argument to show that claims have written description support in a provisional application.
