Portfolio overview

NR ELECTRIC CO., LTD. has been granted 70 US utility patents between 2016 and 2024, placing NR ELECTRIC CO., LTD. at rank #4,969 across all assignees tracked by PlainPatent. This portfolio spans 30 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.9 claims per patent with primary concentration in Y02E (REDUCTION OF GREENHOUSE GAS [GHG] EMISSIONS, RELATED TO ENERGY GENERATION, TRANSMISSION OR DISTRIBUTION). As a Foreign Corporation, NR ELECTRIC CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 42.9/100 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 30 grants, compared with 40 in the 2015–2019 window — a -25% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. NR ELECTRIC CO., LTD.'s 10.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 30 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark NR ELECTRIC CO., LTD. against peers pursuing similar technology classes.

How to use this portfolio

NR's 70 grants land it in the top 29% 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 — NR ranks #4,969 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in Y02E — see who else leads that technology area. Y02E 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.
