An article at ARS TECHNICA describes how small businesses are being targeted by non-practicing entities (aka Patent Trolls) for patent infringement if they own a scanner that has the capability of scanning a document, then emailing that scanned document to someone. Many new scanners, printers, all-in-one devices now have that capability, and these Patent Trolls are sending out demand letters to all sorts of businesses, including at least one in Connecticut. If you ignore the letter, however, you could be setting yourself up for a default judgement if the Patent Troll files a law suit! Please contact a patent attorney if you do receive such a letter from a Patent Troll.
