Sony Loses

[A Black Falcon]

And look what I found.

From the first time Sony lost this case last September (at the previous court level -- this ruling reaffirmed that one)... no definitive answer, but some ideas about why they didn't sue Nintendo.

Oddly enough, Nintendo was never named in the suit, even though they have rumble technology in their GameCube controllers, and are not openly named as a licensee of Immersion's patents. This could stem to some agreement between Nintendo and Immersion, because Nintendo had patented the Rumble Pack for the Nintendo 64 a year before Immersion was granted their patent. One theory is that should Immersion try to sue Nintendo on the issue, Nintendo could pull their trump card of a previous patent against Immersion and force Immersion to lose their patent. Either that, or somehow Nintendo's GameCube controller uses their own technology that stems from their Rumble Pack patent, and thus would not infringe upon Immersion's patents.

Sounds reasonable...
