Portfolio overview

Nidec Tosok Corporation has been granted 144 US utility patents between 2016 and 2025, placing Nidec Tosok Corporation at rank #2,695 across all assignees tracked by PlainPatent. This portfolio spans 54 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.9 claims per patent with primary concentration in H02K (DYNAMO-ELECTRIC MACHINES). As a Foreign Corporation, Nidec Tosok Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Nidec sits between Kodak Alaris, Llc (144 patents, rank #2,691) and Showa Denko Materials Co., Ltd. (144 patents, rank #2,699) - the closest US assignees by grant volume. The composite Innovation Score of 53.1/100 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 123 grants, compared with 21 in the 2015–2019 window, a +486% 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. Nidec Tosok Corporation's 9.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 54 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Nidec Tosok 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.
