STMicroelectronics (Research & Development) Limited

STMicroelectronics (Research & Development) Limited has been granted 306 US utility patents between 2015 and 2025, placing STMicroelectronics (Research & Development) Limited at rank #1,373 across all assignees tracked by PlainPatent. This portfolio spans 73 distinct Cooperative Patent Classification (CPC) subclasses, averaging 22.2 claims per patent with primary concentration in G01S (RADIO DIRECTION-FINDING; RADIO NAVIGATION; DETERMINING DISTANCE OR VELOCITY BY USE OF RADIO WAVES; LOCATING OR PRESENCE-DETECTING BY USE OF THE REFLECTION OR RERADIATION OF RADIO WAVES; ANALOGOUS ARRA). As a Foreign Corporation, STMicroelectronics (Research & Development) Limited is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 64.9/100 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 150 grants, compared with 156 in the 2015–2019 window — a -4% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. STMicroelectronics (Research & Development) Limited's 22.2 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while a multi-domain presence across 73 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark STMicroelectronics (Research & Development) Limited against peers pursuing similar technology classes.
