Couple of simple suggestions for patents.
It would be nice if it was clearer on the patent list with the icon whether the patent is held by this company, or if the product is locked out by the patent.
I see that “off patent” has its own icon - something like that. Maybe be worth using different colours. i.e. Blue for owner, Green for off patent, red for locked-out.
Slightly more effort, but how about a patent allowing sale of that product, but the patent holder gets 20% (or whatever) of the combined value. Maybe even have two types of patent, one that blocks entirely, and the other that allows sales but takes 20%. You’d use the former when the competitor is flooding the market, and the later when you can’t be bothered to build out yourself.
