Shockwave Medical's IPR appeal added a high-value medical-device technology to the 2025 PTAB record.
The Board had found most challenged claims of the asserted patent unpatentable as obvious while leaving one claim standing. The Federal Circuit appeal tested those competing outcomes.
For medical-device patent owners, the case highlights how device claims can be sliced claim by claim, with different limitations producing different obviousness results.
The case should be grouped with medical-device IPRs where clinical importance does not eliminate the need for precise prior-art distinctions.
