@kcorp2003:
I have to agree and I think there should be a limit on how long things can be patented, say a time line of 3 years, after that, no one can patent it. Ban patent sales too, if you don't want a patent, then it's voided as if the 3 years has already passed.
Only someone which a fully working product can patent it, and if something is to simple, like a discount during a specific time period, then it's not possible to get a patent. Patenting something that someone else has already done should be criminalized.
Patent can't include derivation of mathematics or someone else genes.
That would make things so much easier and products should get cheaper as there will not be need of that many lawyers, maybe up to 40% cheaper products and companies who can't get profit within 3 years of a patented product, then they haven't had a good idea and it's not worth to protect with a patent any longer.
