CENTRAL IRON AND STEEL RESEARCH INSTITUTE

CENTRAL IRON AND STEEL RESEARCH INSTITUTE has been granted 20 US utility patents between 2015 and 2025, placing CENTRAL IRON AND STEEL RESEARCH INSTITUTE at rank #14,513 across all assignees tracked by PlainPatent. This portfolio spans 28 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.9 claims per patent with primary concentration in Y02P (CLIMATE CHANGE MITIGATION TECHNOLOGIES IN THE PRODUCTION OR PROCESSING OF GOODS). As a Foreign Corporation, CENTRAL IRON AND STEEL RESEARCH INSTITUTE is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 42.3/100 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 13 grants, compared with 7 in the 2015–2019 window — a +86% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. CENTRAL IRON AND STEEL RESEARCH INSTITUTE's 8.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 28 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark CENTRAL IRON AND STEEL RESEARCH INSTITUTE against peers pursuing similar technology classes.
