Portfolio overview

ST. Marianna University School OF Medicine has been granted 9 US utility patents between 2017 and 2025, placing ST. Marianna University School OF Medicine at rank #30,097 across all assignees tracked by PlainPatent. This portfolio spans 11 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.3 claims per patent with primary concentration in A61P (SPECIFIC THERAPEUTIC ACTIVITY OF CHEMICAL COMPOUNDS OR MEDICINAL PREPARATIONS). As a Foreign Corporation, ST. Marianna University School OF Medicine is one of the more focused assignees in the PatentsView dataset. By volume, St. sits between Spinnova OY (9 patents, rank #30,093) and Step2gold Co., Ltd. (9 patents, rank #30,101) - the closest US assignees by grant volume. The composite Innovation Score of 31.6/100 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 5 grants, compared with 4 in the 2015–2019 window, a +25% 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. ST. Marianna University School OF Medicine's 14.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 11 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark ST. Marianna University School OF Medicine against peers pursuing similar technology classes.

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
