Portfolio overview
Southwest Jiaotong University has been granted 75 US utility patents between 2017 and 2025, placing Southwest Jiaotong University at rank #4,690 across all assignees tracked by PlainPatent. This portfolio spans 81 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.6 claims per patent with primary concentration in B60L (PROPULSION OF ELECTRICALLY-PROPELLED VEHICLES ; SUPPLYING ELECTRIC POWER FOR AUXILIARY EQUIPMENT OF ELECTRICALLY-PROPELLED VEHICLES ; ELECTRODYNAMIC BRAKE SYSTEMS FOR VEHICLES IN GENERAL ; MAGNETIC SU). As a Foreign Corporation, Southwest Jiaotong University is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 65.1/100 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 72 grants, compared with 3 in the 2015–2019 window — a +2300% 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. Southwest Jiaotong University's 8.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 81 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Southwest Jiaotong University against peers pursuing similar technology classes.
