Burdens Can't Be Avoided No Matter How They're Dressed Up

Addressing a multitude of issues, the US Court of Appeals for the Federal Circuit affirmed the district court's ruling dismissing infringement of one patent and finding a trade dress invalid but reversed the invalidation of the other patent and vacated dismissal of an inequitable conduct defense. Mosaic Brands, Inc. v. Ridge Wallet LLC, Case Nos. 22-1001, -1002 (Fed. Cir. Dec. 20, 2022) (Newman, Prost, Stark, JJ.)

Mosaic Brands sued Ridge Wallet alleging infringement of a patent relating to a combination money clip and card holder adapted to retain paper currency and to removably store flexible cards such as credit cards, as well as Mosaic's associated trade dress. Ridge denied the allegations and counterclaimed that Mosaic infringed a Ridge patent directed to a nearly identical wallet. In response to the counterclaim, Mosaic raised inequitable conduct as an affirmative defense.
