Grace Instruments Industries LLC v. Chandler Instruments Company, LLC et al.
In early 2023, B&L prevailed at the United States Court of Appeals for the Federal Circuit on behalf of client Grace Instruments. reversed the District Court’s final judgment in a patent infringement case.
The District Court had previously found the term “enlarged chamber” of Grace’s asserted patent-in-suit, U.S. Patent No. 7,412,877, invalid as indefinite under 35 U.S.C. § 112, ¶2. The Federal Circuit panel disagreed, reversing the District Court’s invalidity decision, and reinstated the validity of Grace Instruments’ patent-in-suit.
