CAFC Rejects Bid for Attorney Fees in Cannabis Patent Suit

The U.S. Court of Appeals for the Federal Circuit (CAFC) issued a precedential decision Monday affirming a district court’s ruling that denied attorney fees and sanctions to Pure Hemp Collective, Inc. over a patent infringement suit brought against it by United Cannabis Corporation. The patent at issue, U.S. Patent No. 9730911, covers “Cannabis Extracts and Methods of Preparing and Using Same.” United Cannabis sued Pure Hemp for infringement in July 2018, but, following United Cannabis’ bankruptcy proceedings, the parties stipulated to the dismissal of the patent case. United Cannabis’ infringement claims were dismissed with prejudice while Pure Hemp’s invalidity and inequitable conduct counterclaims were dismissed without prejudice.

Obviousness Ruling Based on Mischaracterizations of Reference Overturned by CAFC

But what is refreshing and important in the Federal Circuit’s opinion is that mischaracterizations of references relied upon by the patent examiner (or the BPAI) for obviousness rulings are not to be simply glossed over as “harmless error.” Put differently, the Chapman decision gives patent applicant’s a viable legal basis to hold a patent examiner’s (as well as the BPAI’s) “feet to the fire” to challenge an obviousness (or anticipation) rejection based on one or more mischaracterizations of a reference.
