Intellectual property idea
I've been thinking about ways to improve intellectual property for a while, and I think I've got an idea. Limit exclusivity to a short period, say 5 years for copyrights and 2 for patents, but have low fixed-rate royalties for profits above a certain minimum off derivative works, and higher rates for straight-up copies. Let that go for another, say, 25 years for copyrights and 8 for patents.
Obviously the numbers need work, but what other problems are there with this?
Intellectual property idea
I think trademarks are fine as-is, for the record, as long as the rules are enforced correctly. So that would help prevent someone claiming to be the original/official version of something someone else came up with.
