Short of invalidating a patent, can the outcome of IPR dictate the outcome of a district court case? The interplay between PTAB and district courts remains uncertain. As we’ve previously reported here and here, sometimes district courts give weight to PTAB decisions, and sometimes they don’t.

PTAB Drops the Hammer on Petitioners: Five IPR Petitions Denied on the Same Day
The Patent Trial and Appeal Board (PTAB) is granting inter partes review (IPR) petitions at a 70% clip. Imagine the surpris
e, then, when on a single day, September 16, 2015, petitioners went an incredible 0 for 5—the PTAB denied five petitions for IPR and granted none! It seemed like a statistical improbability. Maybe a signal that the tides have turned for patent challengers?

Mind The Gap: The PTAB Will Not Bridge It For You
Petitioners should beware gaps in their evidence and reasoning. Two DepoMed patents recently survived their second IPR challenge because the petitioner failed to meet its burden of proof. The PTAB rejected petitioner’s obviousness arguments as “overly vague and nonspecific,” concluding that petitioner failed to “explain persuasively why or how a person of ordinary skill in the art would modify the drug formulation” of the prior art to develop the claimed formulation, and failed to show a reasonable expectation of success.

PTAB Denies Institution of Another Investment Fund IPR Petition, Refusing to Ignore Claim Limitation Under BRI Standard
Score another win for pharma against investment funds-turned-IPR petitioners. On September 21, 2015, the PTAB denied institution of Ferrum Ferro Capital, LLC’s (“FFC”) petition for IPR of an Allergan patent claim related to its Combigan® eye-drop product for treating glaucoma. This dispute has attracted publicity for having bled into the courts, where Allergan has sued FFC for extortion, unfair competition, and malicious prosecution. The PTAB’s non-appealable denial of FFC’s petition is obviously a significant victory for Allergan, and follows the PTAB’s recent denials of two IPR petitions filed by the Coalition For Affordable Drugs.

PTAB Denies Institution of Two IPR Petitions Filed by Hedge Fund
As the patent community anxiously awaits the PTAB’s decision concerning whether the Coalition For Affordable Drugs (CFAD) should be sanctioned for filing an IPR petition against a Celgene patent¹, the PTAB recently denied institution of two IPR petitions² the CFAD filed concerning two Acorda patents that cover Ampyra, a billion-dollar drug for treating multiple sclerosis. The CFAD is a wholly owned subsidiary of a hedge fund managed by Kyle Bass and, since February 2015, Bass and the CFAD have filed twenty nine IPR petitions against more than twenty patents different patents belonging to at least fifteen different companies.

Put Away The Blunderbuss – Attention to Detail and Thoroughness Are Needed in Preparing an IPR Petition
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.

Gamble At Your Own Risk – The Danger Of Petition Overkill
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.

Grinning Patentees Get A Mulligan

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.

Is the Coalition for Affordable Drugs Abusing the IPR Process?
The PTAB granted leave on June 9 for the patent owner, Celgene Corporation, to file a motion for sanctions seeking dismissal in several IPRs¹ filed by the Coalition for Affordable Drugs. The Coalition for Affordable Drugs, an organization created by the hedge fund Hayman Credes Master Fund L.P., has filed multiple IPRs against pharmaceutical companies with the publicly announced intention to lower drug prices for everyone by invalidating patent protections that it contends have little value.

Claims Found Obvious Even Though Petitioner Waited Until Reply to Present Expert Testimony
It’s well understood that waiting until reply to present any expert testimony comes with a risk that the testimony will be excluded. But that’s not what happened in a recent IPR, where a petitioner waited until reply to present such testimony, and the PTAB, in view of the straightforward nature of the technology, found the challenged claims obvious.
