Today in 2010, US Patent D609053 S1 was issued, an invention of Ramses Dingenouts, assigned to Heineken Supply Chain B.V., for his “Beer Glass.” There’s no Abstract, and the entire application is just one sentence. “The ornamental design for beer glass, as shown and described.”
Obviously, this designed has been used by Heineken as a proprietary glass in recent years, over the five years since the patent was granted.
One of my favorite beer glasses, handed at Costco one day, several years back. It has yet to hold a Heineken and I doubt it ever will.
