Two Russian inventors have filed a patent violation lawsuit with a Moscow court against Sony Electronics in Russia.
They claim that a rear touchpad installed on Sony's new high-powered handheld console PlayStation Vita violates their patent, registered in Russia, which describes alternative ways of controlling an electronic device.
The claimants demand that sales of Vita in Russia be stopped and existing stocks destroyed, CNews portal reported.
Sony Electron-ics has not commented on the claims so far. The court will review the case March 21.
Long-awaited PlayStation Vita, which also features front touch screen, the usual buttons and analogue sticks and is considered Internet user-friendly, hit the shelves in Russia Wednesday.
Sony introduced the new console in Japan in December 2011 and sold about 600,000 devices so far. Sales in the US and Europe started Tuesday.
