Portfolio overview

Changchun Institute of Applied Chemistry Chinese Academy of Sciences has been granted 37 US utility patents between 2015 and 2025, placing Changchun Institute of Applied Chemistry Chinese Academy of Sciences at rank #8,558 across all assignees tracked by PlainPatent. This portfolio spans 44 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.1 claims per patent with primary concentration in H10K (ORGANIC ELECTRIC SOLID-STATE DEVICES). As a Foreign Corporation, Changchun Institute of Applied Chemistry Chinese Academy of Sciences is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 45.0/100 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 24 in the 2015–2019 window — a -46% 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. Changchun Institute of Applied Chemistry Chinese Academy of Sciences's 12.1 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 44 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Changchun Institute of Applied Chemistry Chinese Academy of Sciences against peers pursuing similar technology classes.
