Portfolio overview

Toagosei Co., Ltd. has been granted 135 US utility patents between 2015 and 2025, placing Toagosei Co., Ltd. at rank #2,855 across all assignees tracked by PlainPatent. This portfolio spans 67 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.0 claims per patent with primary concentration in C08F (MACROMOLECULAR COMPOUNDS OBTAINED BY REACTIONS ONLY INVOLVING CARBON-TO-CARBON UNSATURATED BONDS). As a Foreign Corporation, Toagosei Co., Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Toagosei sits between Spine WAVE, Inc. (135 patents, rank #2,851) and IMAM Mohammad IBN SAUD Islamic University (134 patents, rank #2,859) - the closest US assignees by grant volume. The composite Innovation Score of 55.2/100 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 68 grants, compared with 67 in the 2015–2019 window, a +1% 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. Toagosei 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 67 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Toagosei Co., Ltd. against peers pursuing similar technology classes.

Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
