A suddenly hatched company is suing largest mobile firms in the US over numerous patents infringement. Apple, Research in Motion, AT&T, Insight Enterprises, LG Electronics, Motorola, Pantech Wireless, Samsung and Sanyo are accused of violating one or more of seven mobile phone–related patents. Those allegedly infringed patents include ones for Bluetooth connectivity, syncing, background processing and other mobile matters.

According to the filing six of the seven pates were initially granted to PalmSource, which was spun out from Palm in October 2003 and acquired by the self-described "global provider of advanced software technologies to the mobile and beyond-PC markets," Access, in 2005.

The filing was submitted with the US District Court of the Eastern District of Texas. The case will be considered by Leonard Davis, who is currently presiding over or has recently closed hundreds of patent infringement cases, including the recent decision that outlawed Microsoft Word.

As for the company itself that filed the suit, SmartPhone Technologies LLC, has no website, doesn't show up in the business directory of its stated hometown of Frisco, Texas, and a search for businesses listed at the address it provides in court documents, 6136 Frisco Square Boulevard, Suite 400, turns up merely law offices, mortgage brokers, a psychotherapist, and a document-shredding service.

SmartPhone Technologies LLC should not be confused with Smartphone Technologies, Inc, the Jacksonville, Florida developer of custom celebrity, entertainment and college sports apps for mobile devices including the iPhone, BlackBerry, and Android handhelds.
