Portfolio overview
SENJU METAL INDUSTRY CO., LTD. has been granted 214 US utility patents between 2015 and 2025, placing SENJU METAL INDUSTRY CO., LTD. at rank #1,881 across all assignees tracked by PlainPatent. This portfolio spans 58 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.7 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, SENJU METAL INDUSTRY CO., LTD. is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 55.3/100 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 119 grants, compared with 95 in the 2015–2019 window — a +25% 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. SENJU METAL INDUSTRY CO., LTD.'s 9.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 58 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark SENJU METAL INDUSTRY CO., LTD. against peers pursuing similar technology classes.
