Southwest Petroleum University

Southwest Petroleum University has been granted 307 US utility patents between 2015 and 2025, placing Southwest Petroleum University at rank #1,364 across all assignees tracked by PlainPatent. This portfolio spans 99 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.7 claims per patent with primary concentration in E21B (EARTH OR ROCK DRILLING; OBTAINING OIL, GAS, WATER, SOLUBLE OR MELTABLE MATERIALS OR A SLURRY OF MINERALS FROM WELLS). As a Foreign Corporation, Southwest Petroleum University is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 62.9/100 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 281 grants, compared with 26 in the 2015–2019 window — a +981% 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 Petroleum University's 7.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 99 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Southwest Petroleum University against peers pursuing similar technology classes.
