Motorola Mobility has withdrawn its claims with regard to its standard-essential patents in its complaint against Microsoft's Xbox before the US International Trade Commission.
The move comes after Microsoft told the ITC in a filing that it expects Motorola to withdraw claims relating to two patents it says are essential to the H.264 standard, in view of a settlement last week between Google and the Federal Trade Commission.
Confirming the new motion before the ITC, a Google spokeswoman, however, declined further comment.
Motorola Mobility was acquired by Google last year for $12.5 billion, to strengthen its patent portfolio in an industry that has become very litigious. But there has been controversy on the extent to which companies should be able to use standard-essential patents to seek injunctions against competitors' products.
Microsoft cited in its filing various documents including a statement last week from the FTC that Google's settlement requires it to withdraw its claims for injunctive relief on standard-essential patents covered under FRAND (fair, reasonable and non-discriminatory) terms, and to offer a FRAND licence to any company that wants to license Google's standard-essential patents in the future.
FTC chairman Jon Leibowitz said that his understanding was that "they're going to stop trying to seek the injunction or the exclusion order at the ITC," when asked if by the terms of the settlement Google would have to withdraw current cases before the ITC.
But there still appears to be considerable ambiguity on whether Google is required under the settlement to withdraw existing injunction actions before the ITC and courts, with persons close to the situation holding that Google was not required under its settlement with the FTC to withdraw the claims against Microsoft.
After the claims on the patents related to H.264 are dismissed, only one more patent will be the subject of investigation, Microsoft said in the filing.
A policy paper released yesterday by the U.S. Department of Justice and the US Patent and Trademark Office stated that a patent owner's voluntary FRAND commitments may also affect the appropriate choice of remedy for infringement of a valid and enforceable standard-essential patent.
"In some circumstances, the remedy of an injunction or exclusion order may be inconsistent with the public interest," according to the paper. An exclusion order may still be an appropriate remedy in certain situations, such as where the putative licensee is unable or refuses to take a FRAND licence and is acting outside the scope of the patent holder's commitment to licence on FRAND terms, or if the putative licensee is not subject to the jurisdiction of a court that could award damages, it added.
