The verdict
AGC holds 235 US patents across 82 technology areas, rank #1,734 of 50,000 tracked assignees.
AGC Glass Europe has been granted 235 US utility patents between 2015 and 2025, placing AGC Glass Europe at rank #1,734 across all assignees tracked by PlainPatent. This portfolio spans 82 distinct Cooperative Patent Classification (CPC) subclasses, averaging 21.0 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 Foreign Corporation, AGC Glass Europe is one of the broader-portfolio assignees in the PatentsView dataset. By volume, AGC sits between Beijing Zhigu RUI TUO TECH Co., Ltd. (236 patents, rank #1,730) and Williams-sonoma, Inc. (235 patents, rank #1,738) - the closest US assignees by grant volume. The composite Innovation Score of 62.6/100 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 136 grants, compared with 99 in the 2015–2019 window, a +37% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. The Foreign 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. AGC Glass Europe's 21.0 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while a multi-domain presence across 82 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark AGC Glass Europe against peers pursuing similar technology classes.

How to use this portfolio
AGC's 235 grants land it in the top 2% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
