This shows how the patent system isn't really working as intended.
This news shows patents these days are increasingly being used like weapons of mass distraction, to offset challenges from competitors. Company A launches a series of patent legal challenges against company B, then company B hits back with its own set of patent legal challenges. Its like a form of legal Mutual Assured Destruction, if they go to court, so the patents end up as just negotiating chips on a table, to allow them to come to some negotiated compromise.
The little guy who invents something and then gets one patent, doesn't have a hope in hell in this kind of battle of multi-billion dollar giant corporations with their own army of high paid lawyers and massive arsenals of thousands of patents to use as weapons against competitors. :(
It shows the patent system is utterly broken. Patents have morphed into a legal battle field weapon for corporate negotiating. :(
