Pinterest has lost a trademark infringement lawsuit against Pintrips, which monitors the price of flights. U.S. District Judge Haywood Gilliam said that Pintrips has the fair use right to use the word "pin" in its name. "Pintrips uses the term pin in the exact same way as Microsoft, Facebook, and the many other companies that have come before it: as a verb for attaching one virtual object to another," he wrote.
