Not an expert on patent law, but believe an invention is protected from the day the patent application is accepted for filing. Which is why you see products on the market stamped "patent pending".christopher wrote:1981!! Wow. Taking a bit of a chance patenting the concept after introduction eh? Then again, getting a patent approved does take an insane amount of time. 1981, kudos to you Sal for your taking the big step. And thanks.
