Portfolio overview

Nidec Corporation has been granted 999 US utility patents between 2015 and 2025, placing Nidec Corporation at rank #454 across all assignees tracked by PlainPatent. This portfolio spans 132 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.4 claims per patent with primary concentration in H02K (DYNAMO-ELECTRIC MACHINES). As a Foreign Corporation, Nidec Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Nidec sits between Nicira, Inc. (1,011 patents, rank #450) and L'air Liquide, Societe Anonyme Pour L'etude Et L'exploitation Des Procedes Georges Claude (988 patents, rank #458) - the closest US assignees by grant volume. The composite Innovation Score of 63.7/100 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 679 grants, compared with 320 in the 2015–2019 window, a +112% 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 Corporation's 13.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Nidec Corporation against peers pursuing similar technology classes.

How to use this portfolio

Nidec's 999 grants land it in the top 2% by Innovation Score, but volume alone doesn't tell you where the strength sits.

  • Read that count against the largest US assignees before treating it as dominance - Nidec ranks #454 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in H02K - see who else leads that technology area. H02K leaders
  • Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
