Corning Optical Communications RF, LLC (f/k/a Corning Gilbert Inc.)

I'll research this company to verify its profile.

Let me verify a few more details on ownership, history, and the litigation context.

Corning Optical Communications RF, LLC (formerly Corning Gilbert Inc., and briefly Corning Gilbert LLC) is a US subsidiary of Corning Incorporated (NYSE: GLW). It is headquartered at 5310 W. Camelback Road, Glendale, Arizona. The business traces to Gilbert Engineering Co., founded in 1957 as a maker of coaxial connectors for the CATV industry, which Corning acquired in 2001; the Delaware entity was renamed Corning Optical Communications RF LLC in January 2014. Corning does not report separate revenue or headcount for this unit, so no independent size figures are available.

Products / operations. It is an operating manufacturer, not a shell or patent-assertion entity. Under the Corning Gilbert brand it designs and makes RF and microwave coaxial interconnect hardware: push-on blindmate connectors (GPO, GPPO, G3PO, G4PO), GMS and SGMS series connectors, broadband coaxial connectors, adapters, cable assemblies and terminators for CATV/broadband, wireless, satellite, military, aerospace and radar applications. Corning has continued to market new products from the business, including the POLYLINK plated-polymer microwave connector launched at IMS 2024, and the unit sits within Corning's optical communications/advanced optics organization.

Litigation posture. The case data show 1 plaintiff case and 0 defendant cases, all at the Patent Trial and Appeal Board. That profile reflects a product company using PTAB inter partes reviews defensively rather than an NPE asserting an acquired portfolio. The tracked matter, Corning Optical Communications RF, LLC v. PPC Broadband, Inc. (2013-06-10), was one of six parallel IPRs Corning filed against patents owned by competitor PPC Broadband after PPC sued Corning for infringement in the Northern District of New York — a two-way district-court dispute, not an Eastern District of Texas NPE suit.

Notable context. At issue in the lead proceeding (IPR2013-00342) was PPC's U.S. Patent 8,323,060 on coaxial cable connectors with electrical continuity members. The Federal Circuit's 2016 decision in PPC Broadband v. Corning Optical Communications RF addressed the claim term "reside around," and the PTAB reversed its invalidity finding on remand (Oct. 12, 2016).
