Vringo, Inc. (NASDAQ: VRNG), a company engaged in the innovation, development and monetization of mobile technologies and intellectual property, today provided an update on proceedings at the U.S. Patent and Trademark Office (USPTO) regarding patents owned by its wholly owned subsidiary, I/P Engine, Inc.

Today, the USPTO issued a first, non-final rejection of the challenged claims in U.S. Patent No. 6,314,420, which is one of the two patents asserted in litigation against Google, as described below.

This result is not unlike the previous three proceedings that Google initiated, which were ultimately resolved in I/P Engine's favor following I/P Engine's submission of rebuttal responses and meetings with the Examiners.

The USPTO has previously issued a reexamination certificate confirming that all of the claims of U.S. Patent No. 6,775,664, the other patent asserted in litigation against Google, remain valid and unchanged, and no reexaminations are pending with respect to the '664 patent.

I/P Engine will continue to follow the USPTO procedures to uphold the validity of the '420 patent.
