Baltimore-based 180s Inc., whose flagship product are ear warmers that wrap around the head, is accusing a national retailer of stealing the patented design in a similar product it is selling in its stores.
180s filed a lawsuit in U.S. District Court in Baltimore against Brookstone Inc., a New Hampshire-based company. The Baltimore company is claiming that Brookstone's "Luxe" earmuffs infringe upon several of its patented designs.
180s is seeking monetary damages against Brookstone for allegedly violating the patents. The Baltimore company has a reputation for aggressively pursuing in court other companies that infringe upon its patents.
