US Court of Appeals for the Federal Circuit Opinions | HVLPO2, LLC v. Oxygen Frog, LLC | Docket: 19-1649 Opinion Date: February 5, 2020 Judge: Kimberly Ann Moore Areas of Law: Intellectual Property, Patents | HVO’s 941 and 488 patents share a specification and are directed to methods and devices for controlling an oxygen generating system, which is used to sustain and manage airflow for torch glass artists who use surface mix glass torches. HVO sued Oxygen Frog for infringement. A jury concluded that claims 1 and 7 of both patents, the only claims tried, would have been obvious under 35 U.S.C. 103. The Federal Circuit reversed. The district court abused its discretion by admitting lay witness testimony regarding obviousness. That testimony, which was directed to the conclusion of obviousness and its underlying technical questions, is the province of qualified experts, not lay witnesses. Admission of that testimony substantially prejudiced the outcome of the case. | |
