Portfolio overview

Tokusen Kogyo Co., Ltd. has been granted 21 US utility patents between 2017 and 2025, placing Tokusen Kogyo Co., Ltd. at #14,332 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 30 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.4 claims per patent with primary concentration in H01B (CABLES; CONDUCTORS; INSULATORS; SELECTION OF MATERIALS FOR THEIR CONDUCTIVE, INSULATING OR DIELECTRIC PROPERTIES). As a Foreign Corporation, Tokusen Kogyo Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Tokusen sits between Thinkanalytics Ltd. (21 patents, rank #14,314) and Transound Electronics Co., Ltd. (21 patents, rank #14,322) - the closest US assignees by grant volume. The composite Innovation Score of 41.9/100 blends portfolio volume, grant velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Grant cadence records the difference between two grant-year windows. Between 2020 and 2024 the company received 10 grants, compared with 8 in the 2015–2019 window, a +25% shift in five-year grant velocity. Both windows cover five complete grant years; the latest PatentsView year is a partial release and is excluded from this comparison, though it still appears in the yearly table and chart below. Grant timing can lag the related application by years, so this comparison does not establish current R&D spending, strategic intent, or a company’s application activity. The Foreign Corporation classification provides context for the assignee record, not a conclusion about its business strategy.

Claim depth and technology breadth describe this aggregate record. Tokusen Kogyo Co., Ltd.'s 6.4 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 30 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
