The next time you see a bottle of Crest mouthwash, take a moment to appreciate the angles of the bottle. Particularly the trapezoidal-shaped surface near the top. Crest really cares about that trapezoid, so much that its parent company, Proctor and Gamble, tried to patent it, Patently-O reports.
We say tried, because the Federal Circuit Court of Appeals ruled this week that P&G did not succeed.
