ServiceNow Inc. has tapped a team from Cooley to fend off a recent patent suit filed by Hewlett-Packard Co.

Cooley partners Michael Rhodes, Heidi Keefe and Mark Weinstein entered their appearances as counsel on Friday in HP v. ServiceNow, 14-00570.

The suit, filed Feb. 6 in U.S. District Court for the Northern District of California, accuses ServiceNow, a rival in the field of IT service management, of infringing eight patents and seeks an injunction to block ServiceNow from future infringement.

HP is represented by Wilmer Cutler Pickering Hale and Dorr partners Mark Flanagan, Mark Selwyn, Joseph Haag and Evelyn Mak.

Not too long ago, the opposing counsel were on the same side of a patent showdown. In 2012, Cooley’s Rhodes and Keefe teamed up with Wilmer to defend Facebook against infringement claims lobbed by Yahoo Inc. on the verge of the social network’s IPO.
