Patent insurance pays a company for losses incurred if the company either infringes - or is accused of infringing - on someone else's patent. Intellectual Property Insurance Services Corp. IPisc of Louisville, Ky. was the only company selling it throughout most of the 1980s in the U.S. Around 1987, a second company called Litigation Risk Management, Inc. from Texas started selling patent insurance through a company called Anco Insurance. In 2010, InsureCast was in the business, and there may be more companies selling patent insurance in the U.S. now. Other companies sell patent insurance in Europe.
