Do dentists vote on the Google doodle or decide on movie ratings?  Not last time we checked.

Google Inc. (GOOG) and the Motion Picture Association of America decided to weigh in on some oral health issues, though.

A long-running battle between the two titans over piracy on the Internet prompts them to enter the fray over a patent case about invisible dental braces, according to a recent story by Susan Decker on bloomberg.com.

The rub: Align Technology Inc. (ALGN), maker of the Invisalign dental system, claims ClearCorrect Operations LLC infringes its patents. Align asked the U.S. International Trade Commission to block ClearCorrect’s transmissions of computerized dental plans from an office in Pakistan to a 3-D printer in the U.S.
