Continental Circuits LLC v. Intel Corp., No. 18-1076 (Fed. Cir. 2019)Annotate this Case
Continental’s 582, 560, 105, and 912 patents are directed to a “multilayer electrical device . . . having a tooth structure” and methods for making the same. The patents, which have since expired, are continuations of one another and thus share substantially the same specification. According to the patents, multilayer electric devices “suffer from delamination, blistering, and other reliability problems,” especially when “subjected to thermal stress.” The inventions of the patents purport to solve this problem by “forming a unique surface structure . . . comprised of teeth that are preferably angled or hooked like fangs or canine teeth to enable one layer to mechanically grip a second layer.” Continental sued. The parties stipulated to a judgment of noninfringement, based on the district court’s claim construction. The Federal Circuit vacated. The district court erred in reading a “repeated desmear process” limitation into the Category 1 Terms.
