Portfolio overview

Bridgestone Corporation has been granted 1,895 US utility patents between 2015 and 2025, placing Bridgestone Corporation at rank #212 across all assignees tracked by PlainPatent. This portfolio spans 166 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.5 claims per patent with primary concentration in B60C (VEHICLE TYRES; TYRE INFLATION; TYRE CHANGING; CONNECTING VALVES TO INFLATABLE ELASTIC BODIES IN GENERAL; DEVICES OR ARRANGEMENTS RELATED TO TYRES). As a Foreign Corporation, Bridgestone Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Bridgestone sits between Casio Computer Co., Ltd. (1,949 patents, rank #208) and Splunk Inc. (1,859 patents, rank #216) - the closest US assignees by grant volume. The composite Innovation Score of 59.8/100 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 653 grants, compared with 1,242 in the 2015–2019 window, a -47% 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. Bridgestone Corporation's 8.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, 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 Bridgestone Corporation 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.
