Fed. Cir. Claim Construction Focuses on Meaning of “A”
In Apple v Corephotonics, the Federal Circuit vacated and remanded a final decision of the PTAB holding that Apple failed to show that challenged claims of U.S. Patent No. 10,225,479 were obvious. Curiously, the Federal Circuit relied on patentee’s use of “a” when conducting claim interpretation of “a point of view (POV) of the Wide camera.” The ‘479 patent is...
Prosecution Disclaimer Pitfalls
In Speedtrack, Inc. v. Amazon.com, Inc. (June 3, 2021), the Federal Circuit affirmed not only the district court’s findings relating to patent infringement, but also the importance of prosecution history when interpreting the claims.

Federal Circuit Uses Claim Construction to Overturn Lack of Enablement: McRO v. Bandai Namco
In its second time considering a patent, the Federal Circuit upheld the district court’s ruling on noninfringement but overturned its ruling of lack of enablement in McRO v. Bandai Namco. The decision rested on the claim construction of one term, “vector.” That construction excluded the accused products from the scope of the patent, but it likewise excluded examples that the...
The Doctrine of Equivalents Fails to Save Patent Infringement Suit: Ethicon Endo-Surgery, Inc., et al, v. Covidien LP
Following a bench trial, the District Court of Massachusetts held that Ethicon’s “shepherd’s hook” design for finger actuation of a forceps is not equivalent to a “finger loop” claimed by Covidien’s patent no. 9,241,759, and thus Covidien had failed to establish infringement for Ethicon’s Enseal X1 Large Jaw vessel sealer. Ethicon Endo-Surgery, Inc. v. Covidien LP, No. 16-12556-LTS (D. Mass.,...
