RPost Sues Adobe and EchoSign for Infringing Five Patents

RPost, the inventor of Registered Email® services and a pioneer of electronic signature services announced today that it has brought suit against Adobe related to the electronic signature services provided by EchoSign which Adobe announced it acquired on July 18, 2011. This suit is about Adobe’s acquired EchoSign electronic signature services that RPost has determined relies on RPost patented technology. RPost has brought suit for infringing five of RPost’s United States patents – patent numbers 6,182,219; 6,571,334; 7,707,624; 7,865,557 and 7,966,372. RPost has asked the US Federal Court to issue an injunction against Adobe to prevent further damages.

RPost’s flagship Electronic Signature and Registered Email® services provide senders legally valid,court admissible evidence of email content, timestamp and delivery, with options to record the recipient’s consent to attached contracts with legal electronic signatures. RPost, founded in 2000, is one of the pioneers in the e-signature service marketplace with its Registered Email legal delivery proof and electronic signature services.

“Electronically signing a document is not difficult, just typing your name at the bottom of a document or email can have all the legal force of a handwritten signature if all parties have proof that you are the author of the specific content. But if you don’t have that proof, then electronic signing is legally worthless. The key element in any system of electronic signature is creating a legally meaningful audit trail of every step of the signature process and associating that audit trail with particular electronic document content. When part of that audit trail involves email, it is on our turf: we pioneered the technology for proof of email and document delivery, including recording recipient reply or signoff on the message content, and have the patents to prove it.”

RPost’s 35 patents granted worldwide have priority over technology dating back to 1995. These patents broadly cover the technologies of verifiable proof for email delivery, recording recipient consent associated with received messages and documents, and value-added outbound email processing. RPost patents have been granted in Australia, Austria, Belgium, Canada, China, Denmark, France, Germany, India, Ireland, Italy, Korea, Luxembourg, Mexico, Netherlands, Portugal, Spain, Sweden, Switzerland, United Kingdom, and the United States; with numerous additional patents pending.
