Federal Circuit Reiterates What Constitutes A Motivation to Combine, A Reasonable Expectation of Success, and Unexpected Results in New Chemical Compounds

Attorney: Sara Pistilli, PharmD.
August 30, 2023

In Sun Pharmaceutical Industries, Inc. v. Incyte Corporation, on August 22, 2023, the Federal Circuit affirmed a Final Written Decision of the Patent and Trial Appeal Board (the Board) of an inter partes review (IPR) asserting the claims of U.S. Patent No. 9,249,149 (the ’149 patent) as obvious under 35 U.S.C. § 103. The central argument was whether Sun’s “octo-deuterated” ruxolitinib analog (CTP-543) and “tetra-deuterated” ruxolitinib analogs, arising from claim 7 of the ’149 patent, were obvious in light of the prior art references presented by Incyte (Rodgers, Shilling, and the Concert Backgrounder).

Claim 7 recited:

The compound of claim 1, in which the compound is selected from the group consisting of:




or a pharmaceutically acceptable salt of any of the foregoing.<... Read more

Bio/Pharma IPRs: Will Institution Rates Rise in Response to USPTO Initiatives?

Attorney: Richard D. Kelly
August 12, 2022

When it comes to IPR petitions filed in the Bio/Pharma space, USPTO data tells us that while Bio/Pharma petitions make up only 8% of the total petitions filed for the fiscal year of 2022 (through June 30, 2022), there is a high intuition rate for those Bio/Pharma petitions. According to USPTO statistics, 80% of the Bio/Pharma cases have been instituted so far this year.  Put differently, 59 of the 74 petitions reviewed were subsequently granted.<... Read more

Sure, A Court Can Rewrite Patent Claims. But Can It Change A Disclosure? (Pavo Solutions, Part II)

Written Description and Creating Ranges from Examples

Attorney: Richard D. Kelly
April 7, 2022

At the close of last year, the Federal Circuit affirmed a decision by the PTAB in IPR2019-00329 that a claimed range created from examples was not patentable because it lacked written description in the application as filed. In its decision the PTAB “second guessed” an examiner’s ex Parte decision that the claimed range had written description in the application as filed.  Written description was at issue because the patent challenged, U.S. Patent 9,687,454 (‘454), filed January 6, 2016, needed benefit of its parent application serial number 12/537,571 published on February 10, 2011, as 2011/0033541 (‘541), to avoid ‘541 from being prior art otherwise, most of the ‘454 claims were anticipated by ‘541. The ‘454 claim 1 is directed to a mucoadhesive film comprising about 40 wt.% to about 60 wt.% of a water-soluble polymeric matrix and claim 7 to a range of from about 48.2 wt.% to about 58.6 wt.%. Neither range was found in the ‘454 patent as filed; the claims were added during prosecution. The ‘454 describes the film as “may contain any desired level of self-supporting film forming polymer”; in “one embodiment, the film forming composition” may be at least 25 weight per cent of the composition; alternatively, at least 50 weight per cent of the composition. No upper limit was described.<... Read more
