Motorola Mobility parent company Google Inc. droped two patents from its infringement case over video-coding patents used in Xbox and smartphones.

In a motion filed today with the U.S. International Trade Commission, Motorola Mobility LLC is asking the Comission to terminate inverstigations related to two patents included in the company's patent infringement complaint against Microsoft.

In November 2010 Motorola sued Microsoft over wireless and video coding patents used in Xbox and its smartphones. Microsoft countered that Motorola was unfairly seeking excessive royalty payments for the H.264 video patents, claiming that the specific patents should be offered on FRAND (fair, reasonable, and nondiscriminatory) basis.

An ITC judge ruled last May that Microsoft's Xbox 360 S video game console should be banned from import into the U.S. because they infringe on Motorola patents.

"Motorola intends to enforce its rights for past damages in the District Court lawsuits," according to the motion filed today by Google.

"We're pleased that Google has finally withdrawn these claims for exclusion orders against Microsoft, and hope that it will now withdraw similar claims pending in other jurisdictions as required by the FTC Consent Order," David Howard, Microsoft's deputy general counsel, said in a statement.
