American Outdoor Brands, Inc. has filed a patent infringement lawsuit against Eposeidon Outdoor Adventure, Inc. and KastKing Fishing Tackle, Inc., alleging unauthorized use of patented technology in interchangeable fillet knife products.
The complaint was filed in the U.S. District Court for the Eastern District of Texas. American Outdoor Brands claims the defendants knowingly violated patent rights related to its BUBBA® multi-flex interchangeable fillet knife line and is seeking injunctive and monetary relief, as well as a finding of willful infringement.
According to the complaint, American Outdoor Brands alleges that Eposeidon began selling KastKing interchangeable fillet knife kits incorporating technology covered by the company’s patents without authorization. The patents at issue include U.S. Patent Nos. 12,285,879 and 12,441,011, with additional patents reportedly pending.
The company argues that its patented designs, including the Flex-Change® locking system, provide improved performance, durability, and precision in its fillet knife products. American Outdoor Brands claims that KastKing deliberately copied these innovations and continued selling the allegedly infringing products despite receiving notice.
Brian Murphy, President and CEO of American Outdoor Brands, said the company has invested heavily in developing proprietary technologies and expanding its patent portfolio, which now includes more than 400 active or pending patents. He stated that protecting intellectual property is critical to maintaining fair competition and innovation within the marketplace.
American Outdoor Brands is seeking a court order requiring the defendants to withdraw the allegedly infringing products from the market. The company is also requesting compensation for past infringement, a finding of willful infringement, treble damages, and recovery of attorneys’ fees.
The case is pending before the U.S. District Court for the Eastern District of Texas, and the defendants have not publicly responded to the allegations.
