Angela and David Porter are the inventors of a patented pet grooming tool that assists groomers in removing a pet’s shedded hair while not pulling out unshed hair of the top coat, and assists in preventing the groomer’s hand from tiring during the process. The Porters began a business based on the patented products, Furminator, Inc., and has successfully sold its products, and developed several markets for them. Furminator has asserted patent infringement against Munchkin, Inc. dba Bamboo, and Kim Laube & Co., claiming that the companies with knowledge of the Furminator product copied and sold its patented product.
