September 7, 2021

     In Post Grant Reviews (PGR) the Patent Trial and Appeal Board (PTAB) may consider all statutory challenges to patent claims including those under 35 U.S.C. § 112.

In re Rudy and the PTO 101 Guidance

Attorney: Richard D. Kelly
April 22, 2021

The USPTO 101 Guidance document has been under a cloud when Judge Brinkema refused to follow the guidance in Cleveland Clinic Found. V. True Health Diagnostics LLC., affirmed at 760 F. App'x. 1013, 1020 (Fed. Cir. 2019). Cleveland Clinic relied on Guidance example 29, claim 1 to assert that its claims were patent eligible since they were drafted in the same manner. The Federal Circuit in rejecting the argument found the 101 Guidance example 29, claim 1 to be "strikingly" similar to claim 1, see760 F. App'x. at 1020, which the Federal Circuit held was patent ineligible. The guidance teaches that example 29, claim 1 is patent eligible. The USPTO has not responded to the Court's criticism and example 29 continues to appear in the Guidance unchanged.... Read more

Attorney: Grace Kim

Janssen Pharmaceutica. N.V., No. 2021-1071, slip op. at 12 (Fed. Cir. March 12, 2021) (precedential).<... Read more

NHK-Fintiv Rule Challenges Look Futile at Federal Circuit

Attorney: Grace Kim
April 6, 2021

The NHK-Fintiv rule allows the Patent Trial and Appeal Board (PTAB) to deny institution of an inter partes review petition based on the progress of a parallel U.S. district court proceeding of the same patent. The rule was established under former USPTO director Andrei Iancu in 2018, in NHK Spring v. Intri-Plex., No. IPR2018-00752, Paper 8 (PTAB Sept. 12, 2018) (precedential). As a result of the restrictions opposed by the NHK-Fintiv Rule, many petitioners have been facing increasing challenges in seeking review at the PTAB for patents where there is a parallel district court proceeding.<...
