Portfolio overview

Institute OF Metal Research Chinese Academy OF Sciences has been granted 10 US utility patents between 2015 and 2024, placing Institute OF Metal Research Chinese Academy OF Sciences at rank #26,538 across all assignees tracked by PlainPatent. This portfolio spans 23 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.2 claims per patent with primary concentration in C22C (ALLOYS). As a Foreign Corporation, Institute OF Metal Research Chinese Academy OF Sciences is one of the more focused assignees in the PatentsView dataset. By volume, Institute sits between Inspirato, Llc (10 patents, rank #26,534) and Intelsat US Llc (10 patents, rank #26,542) - the closest US assignees by grant volume. The composite Innovation Score of 39.2/100 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. Between 2020 and 2025 the company received 4 grants, compared with 6 in the 2015–2019 window, a -33% 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. Institute OF Metal Research Chinese Academy OF Sciences's 12.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 23 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Institute OF Metal Research Chinese Academy OF Sciences against peers pursuing similar technology classes.
