The verdict
PPG holds 586 US patents across 141 technology areas, rank #783 of 50,000 tracked assignees.
PPG Industries Ohio, Inc. has been granted 586 US utility patents between 2015 and 2025, placing PPG Industries Ohio, Inc. at rank #783 across all assignees tracked by PlainPatent. This portfolio spans 141 distinct Cooperative Patent Classification (CPC) subclasses, averaging 19.2 claims per patent with primary concentration in C09D (COATING COMPOSITIONS, e.g. PAINTS, VARNISHES OR LACQUERS; FILLING PASTES; CHEMICAL PAINT OR INK REMOVERS; INKS; CORRECTING FLUIDS; WOODSTAINS; PASTES OR SOLIDS FOR COLOURING OR PRINTING; USE OF MATERI). As a US Corporation, PPG Industries Ohio, Inc. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, PPG sits between Tohoku University (589 patents, rank #779) and Children's Medical Center Corporation (583 patents, rank #787) - the closest US assignees by grant volume. The composite Innovation Score of 64.7/100 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 304 grants, compared with 282 in the 2015–2019 window, a +8% 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. PPG Industries Ohio, Inc.'s 19.2 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 PPG Industries Ohio, Inc. against peers pursuing similar technology classes.

How to use this portfolio
PPG's 586 grants land it in the top 1% 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.
