Wouldn't they just get a homeless guy to register it, and then transfer it over to them? I'm all for the intent behind your system but execution has gotta be airtight
Then charge a transfer fee based on company size. Which they do currently have different fees based on size of company but I'm pretty sure it's negligible. The other problem is patent trolls. So, you might want to tie fees every year to lack of sales. That would also force companies to let the patents go faster.
