Seems interlink might be bigger than I presumed. Whatever though. This is exactly why I've always been in favor of new copyright legislation. Basically, what I'd like is a few new additions, which are basically due to the realities of the internet age and of patent farms.
1. World is fricking huge now. Hueg like XBOX even. (sorry if you guys don't get the joke) It's extremeley difficult to search the world over to see if someone's doing the same thing you are. The accusing company should be expected to prove beyond a certain reasonable standard that a company is actually willfully stealing their idea and violating their patent.
2. The accusing company must be able to prove that they are making legitimate and significant progress towards developing the technology they have a patent on. If they are not, they should be subject to losing their claim to patent and no further company should be allowed to attempt to obtain exclusivity.
3. The two technologies need to be very similar in design and function to avoid the kind of situation we saw between Konami and Andamiro in the case of Dance Dance Revolution vs Pump It Up. Konami basically tried to claim that PIU was simply a rip off of DDR for being a dance game that uses a dance pad (though PIU's sensor design and configuration was quite different). In short, Konami argued that any kind of dance game of any type violated their patent, which was a ridiculous claim, and hence, they got the smackdown in criminal court (though they succeded to some degree in a later civil suit).
Basically, we need laws to prevent companies from stifling other companies' creativity in design in the name of profit.
