Patent No-Longer Pending

Posted by Matt Blumberg on

Back in 1999, there was no way to easily stay connected if you changed ISPs. No post office for email. So we created one – Return Path ECOA. More than 31 million consumers have used our ECOA service to stay in touch after an email address change – and we’ve been able to connect them with more than 400 companies and countless personal contacts using our services.

Now, the ECOA process that we designed has been granted patent 7,080,122 by the U.S. Patent and Trademark Office. ECOA matters now more than ever, not only helping companies keep in touch with customers, but also playing a role in email deliverability. (Keeping email lists clean and current reduces filtering caused by unknown user errors.)

We’re proud of the patent and what it means for our company. And we’re thrilled to have two of the technical inventors – George Bilbrey and Andy Sautins – still with us pioneering even more great email solutions. If you care to read the patent details, you can do so here.

This is another notch on our innovation belt — Return Path also holds patents for email forwarding and the double opt-in email registration process. Here’s to more great inventions to come!
