Portfolio overview
NIPPON STEEL STAINLESS STEEL CORPORATION has been granted 26 US utility patents between 2020 and 2025, placing NIPPON STEEL STAINLESS STEEL CORPORATION at rank #11,743 across all assignees tracked by PlainPatent. This portfolio spans 22 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.7 claims per patent with primary concentration in C22C (ALLOYS). As a Foreign Corporation, NIPPON STEEL STAINLESS STEEL CORPORATION is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 53.2/100 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. Historical data spans 2020 through 2025, with 26 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. NIPPON STEEL STAINLESS STEEL CORPORATION's 8.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 22 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark NIPPON STEEL STAINLESS STEEL CORPORATION against peers pursuing similar technology classes.
