We saw a huge change in our U.S. Design Patent system two years ago. In May 2024, the Federal Circuit decided LKQ v. GM, and ushering in a flexible obviousness test. The prior test was both rigid and restrictive and very few design patent applications were ever rejected as obvious. The new test opens the door to more rigorous obviousness examination.
U.S. Patent No. 9,491,542 is titled "Automatic Sound Pass-Through Method and System for Earphones" and was challenged by Samsung via inter partes review (IPR) after ST1 sued Samsung for infringement. Samsung argued that claims 1-10 and 13- 20 of the patent were invalid due to obviousness based on three prior art references: Rosenberg, Ichimura and Visser. The PTAB ultimately found all of the challenged claims obvious over combinations of the prior art, but also found unchallenged claims 11 and 12 unpatentable without explanation.
The Federal Circuit affirmed the PTAB determination that claims directed to vehicle identification systems for ridesharing services were unpatentable for obviousness, but reversed the Board's grant of Rideshare's motion to amend substitute claims. Judge Hughes, writing for the panel, held that the substitute claims were directed to patent-ineligible subject matter under 35 U.S.C. 101 because they merely used technology as a tool to improve user experience rather than improving computer functionality itself.
The U.S. Court of Appeals for the Federal Circuit affirmed that Teva Pharmaceuticals did not prove the claims of Janssen Pharmaceuticals' patent for antipsychotic dosing regimens invalid for obviousness.
