Apple Inc. and its law firm got more grief Wednesday for raising a laundry list of appellate issues in their attack on a $1.1 billion patent infringement verdict for the California Institute of Technology.

Apple and co-appellant Broadcom Ltd. argue there was no infringement, that one of the patents is ineligible for protection, that U.S. District Judge George Wu in Los Angeles erred on claim construction, that Caltech’s damages theory was faulty, and that Apple and Broadcom were wrongly estopped from raising invalidity defenses.
