Oh, i'm sure it won't happen.. but it's worth a shot/looking into..
Even if I did.. and everyone started using it anyways.. do I think I could make people stop? Lol, no.. But if other manufacturers take my idea and market it themselves, it would help. That's probably about it though, heh..
Good thinking, definitely could help against other manufacturers blatantly ripping!
Re: Cannabis and patents. Yes, there are patents for cannabis & the related. US gov is a bit hypocritical, they have cannabis related patents themselves. I've also seen other cannabis related patents on the US patent website, particularly with solvent based extractions and edible type patents.
