Portfolio overview

Chulalongkorn University has been granted 8 US utility patents between 2015 and 2025, placing Chulalongkorn University at rank #31,163 across all assignees tracked by PlainPatent. This portfolio spans 20 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.9 claims per patent with primary concentration in Y02P (CLIMATE CHANGE MITIGATION TECHNOLOGIES IN THE PRODUCTION OR PROCESSING OF GOODS). As a Foreign Corporation, Chulalongkorn University is one of the more focused assignees in the PatentsView dataset. By volume, Chulalongkorn sits between Chiome Bioscience Inc. (8 patents, rank #31,159) and CIMC Containers Holding Company Ltd. (8 patents, rank #31,167) - the closest US assignees by grant volume. The composite Innovation Score of 43.9/100 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 4 in the 2015–2019 window, a +0% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Chulalongkorn University's 11.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 20 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Chulalongkorn University against peers pursuing similar technology classes.
