USPTO PatentsView assignee record - 1,734 granted patents across 276 technology areas, active 2015–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: A61K (PREPARATIONS FOR MEDICAL, DENTAL OR TOILETRY PURPOSES).
The verdict
Northwestern holds 1,734 US patents across 276 technology areas, rank #241 of 50,000 tracked assignees.
Northwestern University has been granted 1,734 US utility patents between 2015 and 2025, placing Northwestern University at rank #241 across all assignees tracked by PlainPatent. This portfolio spans 276 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.8 claims per patent with primary concentration in A61K (PREPARATIONS FOR MEDICAL, DENTAL OR TOILETRY PURPOSES). As a US Corporation, Northwestern University is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Northwestern sits between Signify Holding B.v. (1,748 patents, rank #237) and Hitachi Automotive Systems, Ltd. (1,718 patents, rank #245) - the closest US assignees by grant volume. The composite Innovation Score of 67.5/100 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 1,028 grants, compared with 706 in the 2015–2019 window, a +46% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. The US 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. Northwestern University's 16.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Northwestern University against peers pursuing similar technology classes.

How to use this portfolio
Northwestern's 1,734 grants land it in the top 1% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
