Portfolio overview

Corning Incorporated has been granted 3,494 US utility patents between 2015 and 2025, placing Corning Incorporated at rank #104 across all assignees tracked by PlainPatent. This portfolio spans 239 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.4 claims per patent with primary concentration in C03C (CHEMICAL COMPOSITION OF GLASSES, GLAZES OR VITREOUS ENAMELS; SURFACE TREATMENT OF GLASS; SURFACE TREATMENT OF FIBRES OR FILAMENTS MADE FROM GLASS, MINERALS OR SLAGS; JOINING GLASS TO GLASS OR OTHER MA). As a US Corporation, Corning Incorporated is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Corning sits between Sandisk Technologies, Inc. (3,712 patents, rank #100) and Boston Scientific Scimed, Inc. (3,361 patents, rank #108) - the closest US assignees by grant volume. The composite Innovation Score of 71.8/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Filing cadence tells the strategic story. Between 2020 and 2025 the company received 1,968 grants, compared with 1,526 in the 2015–2019 window, a +29% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. The US Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.

Claim depth and technology breadth together indicate competitive posture. Corning Incorporated's 18.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Corning Incorporated against peers pursuing similar technology classes.

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
