United States Federal Circuit

In a patent infringement action involving electronic voltage regulators, International Trade Commission ruling is affirmed in part where: 1) the Commission properly determined the construction of four of the disputed claim limitations, but erred in its narrow construction of one of the limitations; 2) there is substantial evidence to support the Commission's finding that the AAT1143 device infringes plaintiff's patent; 3) the Commission properly determined that claims 2, 3, and 34 of the patent were not invalid as there was no clear and convincing evidence of anticipation; 4) the Commission properly found that the AAT1151 and AAT1265 devices do not infringe on claims 2 and 3 of the patent. The ruling is reversed in part and vacated in part where: 1) the Commission erred in ruling that the AATI146 device does not infringe on plaintiff's patent; 2) the Commission's finding that the AAT1151 and AAT1265 devices do not infringe claim 34 of the patent is internally inconsistent and not supported by substantial evidence; and 3) the Commission's judgment regarding the noninfringement and invalidity of claim 35 of the patent is not supported by substantial evidence and should be remanded for further proceedings.
