Portfolio overview

Taiyo Yuden Co., Ltd. has been granted 1,135 US utility patents between 2015 and 2025, placing Taiyo Yuden Co., Ltd. at rank #392 across all assignees tracked by PlainPatent. This portfolio spans 100 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.8 claims per patent with primary concentration in H01G (CAPACITORS; CAPACITORS, RECTIFIERS, DETECTORS, SWITCHING DEVICES, LIGHT-SENSITIVE OR TEMPERATURE-SENSITIVE DEVICES OF THE ELECTROLYTIC TYPE). As a Foreign Corporation, Taiyo Yuden Co., Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Taiyo sits between Cadence Design Systems, Inc. (1,138 patents, rank #388) and Bytedance Inc. (1,130 patents, rank #396) - the closest US assignees by grant volume. The composite Innovation Score of 61.6/100 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 647 grants, compared with 488 in the 2015–2019 window, a +33% 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. Taiyo Yuden Co., Ltd.'s 10.8 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 Taiyo Yuden Co., Ltd. against peers pursuing similar technology classes.
