Portfolio overview

Bridgestone Sports Co., Ltd. has been granted 279 US utility patents between 2015 and 2025, placing Bridgestone Sports Co., Ltd. at rank #1,488 across all assignees tracked by PlainPatent. This portfolio spans 33 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.0 claims per patent with primary concentration in A63B (APPARATUS FOR PHYSICAL TRAINING, GYMNASTICS, SWIMMING, CLIMBING, OR FENCING; BALL GAMES; TRAINING EQUIPMENT). As a Foreign Corporation, Bridgestone Sports Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Bridgestone sits between Philip Morris USA Inc. (280 patents, rank #1,484) and Teijin Limited (279 patents, rank #1,492) - the closest US assignees by grant volume. The composite Innovation Score of 49.5/100 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 126 grants, compared with 153 in the 2015–2019 window, a -18% 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 Sports Co., Ltd.'s 10.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 33 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Bridgestone Sports Co., Ltd. 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.
