Ricoh, Xerox and Lexmark contest patent demands

Ricoh, Xerox and Lexmark International have filed two petitions for patent reviews in what they say is a continuing effort to protect their customers and dealers against the assertion of these patents by MPHJ Technology Investment.

As part of the Inter Partes Review Petition, Ricoh, Xerox and Lexmark are seeking a ruling from the USPTO that the claims are unpatentable and were fully anticipated by various prior art references.

This is the second in series of actions that the companies have undertaken. In May 2013, Ricoh and Xerox filed action to nullify U.S. Patent No. 7,986,426 and help disable MPHJ's licensing campaign against its customers.

In a joint statement, the companies said "Ricoh, Xerox and Lexmark have clear positions on the protection of intellectual property. We feel strongly that the infringement claims are without merit and the licensing demands of MPHJ are unsubstantiated. We feel it is important to take this action to support our customers and dealer networks from these frivolous claims."
