Capcom is suing fellow Japanese developer and publisher Koei Tecmo for allegedly infringing on a number of its patents, according to a Sankei report translated by Siliconera. The patents relate to letting players in a new game import or unlock content from an older title and the use of a controller vibration to alert players of nearby enemies.
According to Capcom's lawsuit, at least 50 Koei Tecmo titles infringe on its patents. Capcom is seeking ¥980 million (or $9.43 million) in damages, which is apparently equivalent to a licensing fee of around 10 percent of what Capcom claims Koei Tecmo has profited by engaging in infringement. Capcom is also seeking an injunction on the sale of a number of Koei Tecmo's titles.
