IL 153925 titled “SYSTEM AND METHOD FOR AUTOMATICALLY DETECTING NEUTRAL EXPRESSIONLESS FACES IN DIGITAL IMAGES” was first filed by IBM, was assigned to a company called IPO Healthcare based in Guernsey. It was transferred to a US law company called Bollinger Lane LLC in March 2010, and then on to Samsung Electronics later that year. In its peregrinations, the fact that the patent needed periodic renewal went amiss. It wasn’t docketed properly with Samsung’s renewal service.
Based on an affidavit from Samsung, it was determined that the patent going abandoned was unintentional, and the patent office has published a revival request for opposition purposes.
