Portfolio overview

San Diego State University Research Foundation has been granted 37 US utility patents between 2015 and 2025, placing San Diego State University Research Foundation at #8,676 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 54 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.0 claims per patent with primary concentration in A61B (DIAGNOSIS; SURGERY; IDENTIFICATION). As a US Corporation, San Diego State University Research Foundation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, San sits between SUEZ International (37 patents, rank #8,676) and Shenzhen Treasure City Technology Co., Ltd. (37 patents, rank #8,684) - the closest US assignees by grant volume. The composite Innovation Score of 55.0/100 blends portfolio volume, grant velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Grant cadence records the difference between two grant-year windows. Between 2020 and 2024 the company received 19 grants, compared with 17 in the 2015–2019 window, a +12% shift in five-year grant velocity. Both windows cover five complete grant years; the latest PatentsView year is a partial release and is excluded from this comparison, though it still appears in the yearly table and chart below. Grant timing can lag the related application by years, so this comparison does not establish current R&D spending, strategic intent, or a company’s application activity. The US Corporation classification provides context for the assignee record, not a conclusion about its business strategy.

Claim depth and technology breadth describe this aggregate record. San Diego State University Research Foundation's 17.0 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 54 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
