They are increasingly expensive, with the 11.5 year fee being $7700.
You could raise these fees, but how are you going to set them? Based on industry? Ultimately just feels like you’d end up making things harder for individual inventors and easier for big businesses and patent trolls.
Personally I think there are a few reforms that might work. Firstly, software patents do not seem to be useful. They don’t seem to have been required for the development of the software industry, and in general they’ve not been allowed in the past.
Secondly, patents should never prevent the sale or incorporation of a technology into a product. Courts should always demand royalties be paid to the patent holder, based on the profit the infringing party receives.
That’s much more problematic. But it feels like there should be a way to incentivize the continued sale of products so that a company can’t just sit on a patent.
