Yesterday, a federal court issued a major ruling against social media giant Pinterest in a trademark infringement lawsuit against much smaller startup Pintrips.

Pinterest is America’s third largest social network behind Facebook and Twitter. The company is currently valued at $11 billion and has an estimated 80 million monthly users. Users view, share, and organize content by creating “pins” on their virtual pin boards.

Pintrips is self-described as a collaborative trip-planning dashboard for tracking flights and prices across destinations in real time.
