Latest lawsuit accuses new iPad of infringing on 4G patents
In the latest filing, ADAPTIX is claiming that Apple’s new iPad infringes on 4G patents owned by the Dallas-based technology company. The case was filed yesterday in the United States Texas Eastern District Court. ADAPTIX has filed two complains that Apple’s “Retina display iPads sold to AT&T”, at minimum, directly infringe on patent 7,454,212 and 6,947,748 which both relate to “OFDMA with adaptive subcarrier-cluster configuration and selective loading.”

ADAPTIX is recognized as one of the original developers of OFDMA-based system and has a portfolio of 230 issued and pending patents in 13 countries. The majority of its patents are relative to a wide range of 4G technologies.

It is worth noting, however, that Acacia Research Corporation acquired ADAPTIX in January of 2012. Acacia Research Corporation is known for acquiring patent portfolios and aggressively pursuing litigation, otherwise known as patent trolling.
