Corning Inc.

Corning Inc., a multinational technology company, specializes in materials science, focusing on glass, ceramics, and advanced optics. Founded in 1851 by Amory Houghton Sr., the company is headquartered in Corning, New York, U.S., and is publicly traded on the NYSE under the ticker GLW. As of fiscal year 2025, Corning reported approximately 67,200 employees and annual revenues of $15.63 billion, with a market capitalization of around $157.37 billion as of early May 2026.

Corning's diverse product portfolio includes optical fiber and cable for telecommunications, Gorilla Glass for mobile consumer electronics, glass substrates for liquid crystal displays (LCD) and organic light-emitting diodes (OLED), ceramic substrates and filters for automotive emissions control, and laboratory products for life sciences research. The company's innovations underpin various industries, from enabling high-speed internet to providing durable display solutions for consumer devices.

Regarding patent litigation, Corning Inc. operates as an established operating company. Its posture is primarily defensive, as indicated by its single tracked case as a defendant and zero plaintiff cases. The company appeared as a defendant in Unified Patents v. Corning Inc. at the Patent Trial and Appeal Board (PTAB). This suggests Corning is a patent owner actively defending its intellectual property against challenges, likely from entities like Unified Patents, which often targets potentially invalid patents.

A notable historical context for Corning's involvement at the PTAB is the case Corning Optical Communications RF, LLC v. PPC Broadband Inc. (IPR2014-00440). In October 2025, the USPTO Director designated a decision from this case as precedential, establishing stricter requirements for identifying all "real parties-in-interest" in Inter Partes Review (IPR) petitions. This highlights Corning's significant engagement in PTAB proceedings, contributing to the development of patent law and reinforcing its role in defending its extensive patent portfolio.
