PerfectVision filed a declaratory-judgment action against PPC Broadband. The original complaint named six PPC patents, and PerfectVision later moved to add several newly issued PPC patents including the '353 patent; leave to amend was granted June 10, 2013. The August 29, 2014 Markman opinion identified a different set of six patents then at issue, indicating the '353 count may have dropped out, but the specific disposition order was not retrieved.
