The US Patent and Trademark Office filed a “termination decision document” on its database this week that explains why it ruled in Nintendo’s favor. The biggest factors seem to be Gamevice’s use of a flexible bridge to connect the pair of controllers, plus the fact that each controller has to be fitted to a tablet or smartphone. These facets are in contrast to the Switch’s wireless connectivity and its lock-on technology.
It’s not surprising that Nintendo won this lawsuit. The technology of the Switch and Gamevice’s controllers may bear a passing resemblance to one another, but at their core, they’re completely different. But to be fair, the concepts shared between the two companies are close enough that it’s clear that Gamevice wasn’t simply acting as a patent troll.
