Federal Circuit Broadly Affirms PTAB’s Determinations on Analogous Art, Motivation to Combine References, and Obviousness of Claims

The level of deference the Federal Circuit gives to the Board’s IPR decisions has been surprising to many practitioners, considering the Court’s reputation for reversing district court decisions.  The trend of deference to the Board continues, as illustrated in Unwired Planet, LLC v. Google Inc., 2015-1810, -1811, Nov. 15, 2016. Unwired involved one patent, U.S. …

PTAB Reversed for Failing to Explain “Why” a Person of Skill Would Modify the Prior Art

It is no secret that patent owners have, on average, struggled at the PTAB over the last three and a half years.  Some practitioners say that a reason for this result is that the Board many times takes an aggressive approach in the assessment of “obviousness” under Section 103.  Yesterday, the Federal Circuit issued its …

PTAB Rejects Challenge to Onglyza® Patent

The lower burden of proof associated with inter partes reviews should make IPRs attractive to generic pharmaceutical companies, but even with that lower burden, success is not guaranteed, as illustrated by IPR2015-01340.  Mylan Pharmaceuticals challenged AstraZeneca’s patent RE44,186 on saxagliptin, the active ingredient in Onglyza® (used to treat type 2 diabetes).  Mylan’s petition argued the …

Board Has Change of Heart On Rehearing

A request for rehearing is generally considered the IPR equivalent of an end-of-the-game Hail Mary pass, but just like in football, sometimes it works, as illustrated by the Board’s reversal of its prior decision denying review in Handi Quilter, Inc. & Tacony Corporation v. Bernina International AG, IPR2013-00270. The Board originally denied review based on …

Toward a Bullet-Proof Petition – Motivation to Combine

While 8 out of 10 Petitions seeking inter partes review are granted by the PTAB, there remain several key errors that unsuccessful Petitioners make. Among them is the failure to provide sufficient factual basis for a rationale to combine prior art references in an obviousness analysis.

Another IPR Petition Comes Up Short for Failing to Adequately Show Rationale to Combine

Many Patent Owners are finding success in undermining the challenge grounds of a Petition by arguing that the Petition fails to make an adequate showing that a person of ordinary skill in the art would have combined the relied-on references.

Rationale from Denied Ground Used By PTAB In Final Written Decision

Lost a challenge ground in the Board’s Decision to Institute? The Board has given some hope that such denied grounds may still of use in an IPR proceeding in McClinton Energy Group, LLC v. Magnum Oil Tools International, Ltd., IPR2013-00231, involving US Pat. No. 8,079,413. In this decision on a motion for rehearing, the Board affirmed the propriety …

In two separate challenges of a single patent, Dell had lukewarm success with 23 claims being placed in an inter partes review trial, but three claims and multiple grounds also denied by the Board in Dell, Inc. v. Acceleron, LLC (IPR2013-00440 and IPR2013-00443), involving U.S. Pat. No. 6,948,021. The ‘021 patent relates to a computer …
