USPTO PatentsView assignee record - 888 granted patents across 125 technology areas, active 2015–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: H01L (SEMICONDUCTOR DEVICES NOT COVERED BY CLASS H10).
The verdict
Stmicroelectronics holds 888 US patents across 125 technology areas, rank #505 of 50,000 tracked assignees.
Stmicroelectronics, Inc. has been granted 888 US utility patents between 2015 and 2025, placing Stmicroelectronics, Inc. at rank #505 across all assignees tracked by PlainPatent. This portfolio spans 125 distinct Cooperative Patent Classification (CPC) subclasses, averaging 20.1 claims per patent with primary concentration in H01L (SEMICONDUCTOR DEVICES NOT COVERED BY CLASS H10). As a US Corporation, Stmicroelectronics, Inc. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Stmicroelectronics sits between Illumina, Inc. (890 patents, rank #501) and Toyota Boshoku Kabushiki Kaisha (885 patents, rank #509) - the closest US assignees by grant volume. The composite Innovation Score of 63.9/100 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 284 grants, compared with 604 in the 2015–2019 window, a -53% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Stmicroelectronics, Inc.'s 20.1 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, 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 Stmicroelectronics, Inc. against peers pursuing similar technology classes.

How to use this portfolio
Stmicroelectronics's 888 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.
