I do not know. I sent both companies several fishing product ideas only to see they can change one tiny detail and market it as their own. Case in point was "The Poor Man's Fishing Bucket," I protected the drawings through the library of congress too. Both it and the Carterlee worm incubator ideas were stolen and two years later I saw them in stores. My advice is to contact a patent attorney before you submit any ideas. Patents and licensing can be quite pricey.
