Portfolio overview

JX Nippon Mining & Metals Corporation has been granted 350 US utility patents between 2015 and 2023, placing JX Nippon Mining & Metals Corporation at rank #1,216 across all assignees tracked by PlainPatent. This portfolio spans 77 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.5 claims per patent with primary concentration in C23C (COATING METALLIC MATERIAL; COATING MATERIAL WITH METALLIC MATERIAL; SURFACE TREATMENT OF METALLIC MATERIAL BY DIFFUSION INTO THE SURFACE, BY CHEMICAL CONVERSION OR SUBSTITUTION; COATING BY VACUUM EVAP). As a Foreign Corporation, JX Nippon Mining & Metals Corporation is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 54.3/100 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 118 grants, compared with 232 in the 2015–2019 window — a -49% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. JX Nippon Mining & Metals Corporation's 11.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 77 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark JX Nippon Mining & Metals Corporation against peers pursuing similar technology classes.
