Portfolio overview
Dunlop Sports Co., Ltd. has been granted 427 US utility patents between 2015 and 2024, placing Dunlop Sports Co., Ltd. at rank #1,023 across all assignees tracked by PlainPatent. This portfolio spans 39 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.1 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, Dunlop Sports Co., Ltd. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 49.9/100 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 6 grants, compared with 421 in the 2015–2019 window — a -99% 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. Dunlop Sports Co., Ltd.'s 10.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 39 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Dunlop Sports Co., Ltd. against peers pursuing similar technology classes.
