TOKYO--Sony Computer Entertainment is taking some extra measures to protect the name of its next-generation gaming machine, the PlayStation 3. The company recently trademarked the term "P53" (Pee Fifty-Three) in the Japan Patent Office, assigning it the official PS3 logo. Sony's action, although obscure, is reasonably understandable, since P53 looks strikingly similar to PS3, the abbreviation for its PlayStation 3 console. Sony trademarked the term "PLAYSTATIOn" as well, also giving it the PS3 logo. Sony also trademarked some terms it might be using for the Cell chip in the near future, including "Broadband Processor Architecture" (BBPA) and "Cell Broadband Engine" (CBBE).
