USPTO Adapts to CAFC’s New Guidelines: What Design Patent Examiners Need to Know

by Dennis Crouch

On May 22, 2024, the day after the Federal Circuit's en banc LKQ v. GM decision, the USPTO issued a memorandum to its examiners providing updated guidance and examination instructions in light of the court's overturning of the long-standing Rosen-Durling test for determining obviousness of design patents. The memo, signed by USPTO Director Kathi Vidal, aims to immediately align USPTO practices with the more flexible approach outlined by the Federal Circuit, which eliminated the rigid requirements that: (1) a primary reference be "basically the same" as the claimed design, and (2) secondary references be "so related" to the primary reference that features in one would suggest application to the other.  This is a major shift in examination practice for design patents so it will be important to watch the developments to see whether the office ramps up design examination.

Federal Circuit Overrules Rosen-Durling Test for Design Patent Obviousness

by Dennis Crouch

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
