(38,634 posts)I typically discourage small inventors from filing patent applications. The costs are enormous, and the returns typically small to non-existent. My average is better than 1 in 100 for making money; perhaps 1 in 25 made some money - and 1 in 50 made enough money to pay for the costs of patenting the invention.
There are really only two solid reasons I can think of for a small inventor to patent something - they just want to say they have a patent, and they have a company lined up to market which insists on already having a patent application filed. The biggest reason against it is the one you point out. Even if you have a patent, it takes millions to effectively defend it.
Companies are a different matter - if for no reason other than to use offensively against competitors who threaten to sue. Sort of a mutually assured destruction.
