Portfolio overview

Tokuyama Corporation has been granted 202 US utility patents between 2015 and 2025, placing Tokuyama Corporation at rank #1,988 across all assignees tracked by PlainPatent. This portfolio spans 93 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.3 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, Tokuyama Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Tokuyama sits between Invue Security Products Inc. (202 patents, rank #1,984) and Nippon Kayaku Kabushiki Kaisha (201 patents, rank #1,992) - the closest US assignees by grant volume. The composite Innovation Score of 61.9/100 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 127 grants, compared with 75 in the 2015–2019 window, a +69% 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. Tokuyama Corporation's 9.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 93 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Tokuyama Corporation 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.
