Access, the company that owns the rights to the Palm operating system, is renaming Palm OS to Garnet OS. The company has done so to differentiate Garnet OS from Palm Inc, manufacturer of the Treo handset and holders of the Palm trademark.

The announcement comes in tandem with Access' introduction of a new 'Access Powered' mark that will replace 'Palm Powered' in devices designed around the operating system.

Last October Access announced that it would subsume PalmSource and change its name to Access. It then sold PalmSource's trademark rights back to Palm.

This isn't the first time the name Garnet has been associated with Palm OS. In February 2004, PalmSource introduced different names for the Palm operating system - Palm OS 5 became Palm OS Garnet, and Palm OS 6 became Palm OS Cobalt.

Besides Garnet OS, Access' specific focus is in developing a Linux-based platform for mobile phones and other devices. The Access Linux Platform, as the company calls it, will include a compatibility layer for Garnet OS.
