Adobe Sued Over E-Signature Service Patents

Adobe Systems and EchoSign, the electronic signatures company it acquired, were sued by RPost, another electronic signature services company, for alleged infringement of five of its patents relating to electronic signature services. RPost, which said it was in discussions with Adobe before its acquisition of EchoSign, for "a collaborative product alliance," has asked the U.S. District Court for the Eastern District of Texas, Marshall Division to issue an injunction against Adobe to prevent further damages.
