Portfolio overview

Nidec Motor Corporation has been granted 236 US utility patents between 2015 and 2025, placing Nidec Motor Corporation at rank #1,733 across all assignees tracked by PlainPatent. This portfolio spans 61 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.7 claims per patent with primary concentration in H02K (DYNAMO-ELECTRIC MACHINES). As a US Corporation, Nidec Motor Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Nidec sits between ALPS Electric Co., Ltd. (236 patents, rank #1,729) and Tessera Llc (235 patents, rank #1,737) - the closest US assignees by grant volume. The composite Innovation Score of 59.3/100 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 111 grants, compared with 125 in the 2015–2019 window, a -11% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The US 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 Motor Corporation's 16.7 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 61 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Nidec Motor 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.
