The verdict
Yonex holds 10 US patents across 2 technology areas, rank #27,857 of 50,000 tracked assignees.
Yonex Co., Ltd. has been granted 10 US utility patents between 2015 and 2024, placing Yonex Co., Ltd. at rank #27,857 across all assignees tracked by PlainPatent. This portfolio spans 2 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.3 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, Yonex Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Yonex sits between YAMO Pharmaceuticals Llc (10 patents, rank #27,853) and Yunnan Huapu Quantum Material Co., Ltd (10 patents, rank #27,861) - the closest US assignees by grant volume. The composite Innovation Score of 18.2/100 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 5 grants, compared with 5 in the 2015–2019 window, a +0% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Yonex Co., Ltd.'s 6.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while specialization in 2 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Yonex Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Yonex's 10 grants land it in the top 95% 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.
