Portfolio overview

FUSO Chemical Co., Ltd. has been granted 10 US utility patents between 2017 and 2025, placing FUSO Chemical Co., Ltd. at rank #26,312 across all assignees tracked by PlainPatent. This portfolio spans 12 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.8 claims per patent with primary concentration in C01B (NON-METALLIC ELEMENTS; COMPOUNDS THEREOF; ; METALLOIDS OR COMPOUNDS THEREOF NOT COVERED BY SUBCLASS C01C). As a Foreign Corporation, FUSO Chemical Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, FUSO sits between Fujidenolo Co., Ltd. (10 patents, rank #26,308) and Feellife Health Inc. (10 patents, rank #26,316) - the closest US assignees by grant volume. The composite Innovation Score of 38.5/100 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 9 grants, compared with 1 in the 2015–2019 window, a +800% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. FUSO Chemical Co., Ltd.'s 7.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 12 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark FUSO Chemical Co., Ltd. against peers pursuing similar technology classes.
