Portfolio overview

NAKANISHI METAL WORKS CO., LTD. has been granted 48 US utility patents between 2015 and 2025, placing NAKANISHI METAL WORKS CO., LTD. at rank #6,923 across all assignees tracked by PlainPatent. This portfolio spans 35 distinct Cooperative Patent Classification (CPC) subclasses, averaging 5.7 claims per patent with primary concentration in F16C (SHAFTS; FLEXIBLE SHAFTS; ELEMENTS OR CRANKSHAFT MECHANISMS; ROTARY BODIES OTHER THAN GEARING ELEMENTS; BEARINGS). As a Foreign Corporation, NAKANISHI METAL WORKS 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 29 grants, compared with 19 in the 2015–2019 window — a +53% 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. NAKANISHI METAL WORKS CO., LTD.'s 5.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 35 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark NAKANISHI METAL WORKS CO., LTD. against peers pursuing similar technology classes.
