Portfolio overview

Daido Metal Company Ltd. has been granted 117 US utility patents between 2015 and 2025, placing Daido Metal Company Ltd. at rank #3,193 across all assignees tracked by PlainPatent. This portfolio spans 45 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.0 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, Daido Metal Company Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Daido sits between Universite DE Nantes (118 patents, rank #3,189) and GSI Technology Inc. (117 patents, rank #3,197) - the closest US assignees by grant volume. The composite Innovation Score of 51.9/100 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 64 grants, compared with 53 in the 2015–2019 window, a +21% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Daido Metal Company Ltd.'s 9.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 45 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Daido Metal Company 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.
