Prior Civil Action Bars IPR - A precedential decision

September 24, 2019 | Blog | By Ken Jenkins

On August 29, 2019, the Patent Trial and Appeal Board (PTAB) designated as precedential its January 31, 2019 decision in Cisco Systems, Inc. v. Chrimar Systems, Inc.  In Cisco, the PTAB held that 35 U.S.C. § 315(a)(1) bars institution of IPR if the petitioner filed an earlier civil action, even if such action was voluntarily dismissed by the petitioner without prejudice.

We previously reported here on a Patent Trial and Appeal Board (PTAB) decision involving a case in which a patent eligibility rejection was overcome by replacing a “comparing” step with a recitation that the sample is from a particular patient population.  However, because the eligibility rejection was dropped by the examiner before appeal, the PTAB did not revisit the issue.

Under the Mayo/Alice test for patent eligibility, answering the questions of whether any particular claim is “directed to” a “judicial exception” without “significantly more” remains in many ways a substantial and unpredictable challenge for U.S. patent applicants in the diagnostic space.  In cases where the detection processes are typically deemed “routine and conventional” (e.g., PCR) and the targets are known (e.g., expression of a known gene), claims must be crafted in ways that avoid rejections for both patent eligibility and anticipation and/or obviousness over the prior art.  The recent PTAB decision in In re Srivastava et al. expressly addresses obviousness in this context, while highlighting a possible strategy for dealing with patent eligibility challenges as well (Appeal 2017-1981, Application 13/974,007, decided October 22, 2018; hereafter “In re Srivastava”).
