Portfolio overview

NARI Technology Co., Ltd. has been granted 8 US utility patents between 2015 and 2025, placing NARI Technology Co., Ltd. at rank #32,566 across all assignees tracked by PlainPatent. This portfolio spans 18 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.3 claims per patent with primary concentration in H02J (CIRCUIT ARRANGEMENTS OR SYSTEMS FOR SUPPLYING OR DISTRIBUTING ELECTRIC POWER; SYSTEMS FOR STORING ELECTRIC ENERGY). As a Foreign Corporation, NARI Technology Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, NARI sits between Nanjing University & Yancheng Academy OF Environmental Protection Technology AND Engineering (8 patents, rank #32,562) and National University Corp Hiroshima University (8 patents, rank #32,570) - the closest US assignees by grant volume. The composite Innovation Score of 31.0/100 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 6 grants, compared with 2 in the 2015–2019 window, a +200% 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. NARI Technology Co., Ltd.'s 11.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 18 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark NARI Technology Co., Ltd. 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.
