Represented Volvo Penta in competitor-on-competitor patent infringement litigation involving six patents. Volvo Penta’s main U.S.-based competitor, Brunswick Corporation challenged Volvo Penta’s patent on an innovative forward-facing drive in IPR; Volvo Penta responded by filing suit. Brunswick then sued Volvo Penta for alleged infringement of five Brunswick patents; Volvo Penta responded with IPR’s challenging all five patents. The Eastern District of Virginia found all of Brunswick’s patents invalid. The Patent Office initially determined the Volvo Penta patent to be invalid, but the Federal Circuit vacated that decision and remanded the IPR. The parties settled before final written decision. Volvo Penta of the Americas, LLC v. Brunswick Corporation, No. 1:20-cv-01678 (D. Del. 2022)

B/E Aerospace, Inc. v. Safran Cabin, Inc. et al., No. 2:19-cv-01480 (C.D. Cal.) – Representing Zodiac Aerospace and several related entities against B/E Aerospace in a series of a patent infringement matters. The companies are fierce competitors in the market for aircraft interiors, including lavatories. B/E and Safran have been engaged in a series of messy disputes regarding their competing lavatories. We invalidated most of the claims of U.S. Patent No. 8,590,838 titled, “Aircraft Interior Lavatory.”. We are currently handling a matter that B/E brought in the Eastern District of Texas (which has since been transferred to the Central District of California), accusing Safran of patent infringement. The case was stayed after we successfully petitioned for review of three of the five asserted patents before the Patent Trial and Appeal Board, which issued final written decisions finding the asserted claims of those patents invalid. The Federal Circuit affirmed those decisions. The court lifted the stay and we proceeded to file additional re-exams and an inter partes review which again persuaded the court to stay the litigation. The patent subject to IPR was held invalid by the Patent Office. The remaining patents have been rejected in reexamination.

The settlement was structured to be compatible with all versions of the GPL (General Public License), the open-source license under which many Red Hat products are developed and distributed, and provides licenses to the patents for all of Red Hat's products. In addition, the license extends not only to Red Hat and its customers, but also to members of the open-source community who contribute to the development of Red Hat's products.
