If you make a lure and want to patent it "HIRE AN PATENT ATTORNEY" simple as that.
I have three in the procces now and should be pending this spring, but it will take 3yrs to get the full patent and then its only good for 3yrs and has to be renewd, quarterly updated and alot more blah blah blah. Get the attorney and grab your wallet.
All of mine are military related so they are under a tarp in the shop and have been for almost a year.
Its not a quick process, if you would like to talk to mine he has done work for remington,ruger and a few others you would notice but the last bill I got was for an 15min call $250.00
