This is ridiculous! America desperately needs an overhaul of it's patent system. Look at the lengths companies have to go to, to protect themselves of these patent trolls who don't even make any actual product.
Patent troll is anyone who was given a patent based upon application that only consists of proper documentation with no physical product in sales now and maybe ever. So all of the companies which own patents are most likely patent trolls because all of them has some vaporware patents in their portfolio. You think Apple would not sue Samsung for something they have patented decade ago but Samsung wants to release it to the market? Of course they would, so in that scenario is Apple a patent troll or did Samsung steal their idea?
The only proper way to reform patent office is to kill design patents completely and give 5 year leeway for actual patented technology to reach production and any kind of sales distribution. You can't make it into 5 years it means you were sci-fying it so patent becomes invalid or free for all. As a thank you for helping out the world with ideas on paper you are entitled to recognition and some symbolic royalty rate determined by patent office for all of the idea on paper patents no matter what. This way you would stop companies and people for putting out meaningless patents with no intention to build one, if technology is still not there yet you have to wait until it's ready to go ahead and patent it that's why you get 5 years.
