RPost has settled its separate patent infringement suits against both Swiss Post and Canada Post after court-ordered mediation.

RPost said in a terse statement that the settlement terms are “consistent with our intent to vigorously protect our intellectual property everywhere.”

Canada Post, which is paying RPost some undisclosed amount of money under its settlement, has agreed to “block messaging traffic of its epost product to the United States IP address range.”

The settlement resolves RPost’s complaint based on its US patent. It’s got a Canadian patent and will be examining the recently reprised epost that Canada Post is depending on to tickle its revenues to see if it infringes.

The terms Swiss Post accepted are secret but evidently it has agreed to abandon the US market, an undertaking it made to RPost once before and reneged on.

If one digs deep enough on the post’s IncaMail web site there’s a discrete – practically hidden – message that says, “Registration for reception is possible for persons and companies from the USA. Sending is not allowed.” So if an IncaMail subscriber is in the US he can get mail but can’t return it.

Presumably Swiss Post has also dropped its claims that RPost patents are invalid.

RPost also settled patent and trademark infringement charges against Silicon Valley Web Hosting created by the hoster’s now ex-customer Read Notify. RPost is still suing Read Notify.

Meanwhile, RPost has gotten its 46th patent. This one – US No 8,275,845 – covers technology to record the indication of acceptance or rejection of an offer sent by e-mail.

CEO Zafar Khan says it “adds to the electronic transactions and signature patents in RPost’s portfolio.” One of RPost’s proof and tracking patents recently challenged has now been certified as valid after re-examination by the US Patent and Trademark Office.
