8075338

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.

PPC Broadband sued Corning Optical Communications RF LLC. The '431 patent was expressly one of six patents-in-suit, alongside U.S. 8,075,338, 8,366,481, 8,469,740, 8,475,205, and 8,485,845. The final outcome was not confirmed in the sources retrieved.

Corning Optical Communications RF LLC et al. petitioned for inter partes review of U.S. Patent No. 8,075,338. The PTAB never instituted the proceeding, and it was terminated on January 17, 2017 by settlement before institution.
