When Milford intellectual property lawyer Michael Blake got a call last year from a small business facing a sudden legal crisis, he wasn’t exactly sure what sort of problem they were up against.

Blake’s client was Southeastern Employment Services in Old Lyme, which finds jobs for disabled people. It had received a “cease and desist” letter from a company in Texas. FolNer LLC claimed it was the owner of a patent the Connecticut business was infringing upon. The patent in question, Blake said, was for the scanning and emailing function on Hurley’s copier machine.
