Portfolio overview

Yushiro Chemical Industry Co., Ltd. has been granted 6 US utility patents between 2019 and 2025, placing Yushiro Chemical Industry Co., Ltd. at rank #44,175 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.5 claims per patent with primary concentration in C08G (MACROMOLECULAR COMPOUNDS OBTAINED OTHERWISE THAN BY REACTIONS ONLY INVOLVING UNSATURATED CARBON-TO-CARBON BONDS). As a Foreign Corporation, Yushiro Chemical Industry Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Yushiro sits between Yokogawa Saudi Arabia Company (6 patents, rank #44,171) and ZEFR, Inc. (6 patents, rank #44,179) - the closest US assignees by grant volume. The composite Innovation Score of 32.3/100 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 4 grants, compared with 2 in the 2015–2019 window, a +100% 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. Yushiro Chemical Industry Co., Ltd.'s 9.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 14 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Yushiro Chemical Industry 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.
