Portfolio overview

Daihen Corporation has been granted 206 US utility patents between 2015 and 2025, placing Daihen Corporation at rank #1,950 across all assignees tracked by PlainPatent. This portfolio spans 54 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.8 claims per patent with primary concentration in B23K (SOLDERING OR UNSOLDERING; WELDING; CLADDING OR PLATING BY SOLDERING OR WELDING; CUTTING BY APPLYING HEAT LOCALLY, e.g. FLAME CUTTING; WORKING BY LASER BEAM). As a Foreign Corporation, Daihen Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Daihen sits between Transform SR Brands Llc (207 patents, rank #1,946) and Noble Systems Corporation (206 patents, rank #1,954) - the closest US assignees by grant volume. The composite Innovation Score of 53.7/100 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 122 grants, compared with 84 in the 2015–2019 window, a +45% 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. Daihen Corporation's 7.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 54 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Daihen Corporation 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.
