Certain Automated Mechanical Transmission Systems for Medium-Duty and Heavy-Duty Trucks and Components Thereof (ITC Inv. No. 503, 2005); represented respondents ZF Friedrichshafen A.G. and ArvinMeritor, Inc., in this Section 337 patent infringement investigation at the International Trade Commission; in the violation phase of the investigation, the ITC granted respondents’ motion for summary determination with respect to one of the six asserted patents; the ITC also terminated the investigation, at the patent owner’s request, with respect to two other patents and several claims of the remaining three patents; after a ten-day hearing on the merits, the administrative law judge ruled in favor of the respondents on all but one claim of one patent; the respondents designed around the one remaining claim, and Charles helped them work with Customs and Border Protection to ensure continuous importation of the redesigned product; when the patent owner brought an enforcement action, Charles helped ZF and ArvinMeritor become the first respondents ever to defend successfully against such a proceeding at the ITC; as a result of this victory, ZF and ArvinMeritor were able to continue the importation and sale of the redesigned product without interruption.*
