RPost Sues DocuSign for Infringing Four Patents

DocuSign Infringes on RPost-Pioneered Technology for Electronic Signature Services to Record Email Recipient Consent.

LOS ANGELES, CA — Jul 7, 2011 — RPost, the inventor of Registered Email services and a pioneer of electronic signature services, announced today that it has brought suit against DocuSign for infringing four RPost patents. RPost has asked the US Federal Court (Texas Eastern District) to issue an injunction against DocuSign 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 irrefutably 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 message legal delivery proof and electronic signature services.

“We have seen the marketplace put more emphasis on electronic signature services that produce signed contracts with high evidential weight, assure electronic signatures have been applied to contracts in a manner that is legally valid, and return auditable proof records to all signing parties. This has been the core of RPost technology for years,” remarks RPost CEO Zafar Khan. “With the current emphasis on legal electronic signatures, we are now seeing others using RPost technology without permission and ignoring very clear references to RPost’s patent position.”

RPost has evaluated DocuSign’s services and has determined that essential elements of those services infringe four of RPost’s United States patents — patent numbers 6,182,219; 6,571,334; 7,707,624 and 7,966,372. DocuSign is knowingly taking property at will for what appears to be its own financial gain.

“We have patents issued worldwide,” Khan says. “We intend to defend all of our intellectual property, everywhere.”

The suit is only the latest battle in an RPost campaign to enforce its patent rights. 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.
