Apple has apparently decided to abandon its trademark application for the term "POD." Apple filed for the trademark in Canada on July 2004. After a series of changes required by the Canadian government and extensions that span seven years, Apple has decided to abandon the patent. The abandonment procedure began on December 2010 and was finalized on April 13, 2011.
The term "iPOD" is still covered by an Apple trademark, but the word "POD" is now up for grabs. Look for the next ePOD eReader or aPOD mp3 player to hit the market in the coming months.
