Portfolio overview

TOYO Kohan Co., Ltd. has been granted 94 US utility patents between 2015 and 2025, placing TOYO Kohan Co., Ltd. at rank #3,864 across all assignees tracked by PlainPatent. This portfolio spans 52 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.3 claims per patent with primary concentration in B32B (LAYERED PRODUCTS, i.e. PRODUCTS BUILT-UP OF STRATA OF FLAT OR NON-FLAT, e.g. CELLULAR OR HONEYCOMB, FORM). As a Foreign Corporation, TOYO Kohan Co., Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, TOYO sits between Skullcandy, Inc. (94 patents, rank #3,860) and The Trustees Of The Stevens Institute Of Technology (94 patents, rank #3,868) - the closest US assignees by grant volume. The composite Innovation Score of 53.5/100 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 53 grants, compared with 41 in the 2015–2019 window, a +29% 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. TOYO Kohan Co., Ltd.'s 6.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 52 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark TOYO Kohan 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.
