A "Bare Hope of A Result": The Second CRISPR Patent Appeal

On May 12, 2025, the US Court of Appeals for the Federal Circuit issued its second decision in the long-running CRISPR patent dispute between the Regents of the University of California and related institutions (CVC) and the Broad Institute. This Perspective recounts the principal dispute to date, reviews the Federal Circuit's recent opinion, and provides a critique of its analysis. In particular, this Perspective highlights how the decision is self-contradictory and in tension with patent law's conception doctrine-when an inventor has formed a "definite and permanent" idea of an invention in the mind or whether the invention was little more than a "bare hope" of a result. This Perspective briefly concludes with the implications of this recent decision and where the underlying dispute is likely headed.
