In a highly anticipated en banc decision, the Federal Circuit has overruled the longstanding Rosen-Durling test for assessing obviousness of design patents. LKQ Corp. v. GM Global Tech. Operations LLC, No. 21-2348, slip op. at 15 (Fed. Cir. May 21, 2024) (en banc). The court held that the two-part test's requirements that 1) the primary reference must be "basically the same" as the claimed design, and 2) any secondary references must be "so related" to the primary reference that features from one would suggest application to the other, "impose[] limitations absent from § 103's broad and flexible standard" and are "inconsistent with Supreme Court precedent" of both KSR (2007) and Whitman Saddle (1893). Rejecting the argument that KSR did not implicate design patent obviousness, the court reasoned that 35 U.S.C. § 103 "applies to all types of patents" and the text does not "differentiate" between design and utility patents.  Therefore, the same obviousness principles should govern.  This decision will generally make design patents harder
