Portfolio overview

NDSU Research Foundation has been granted 73 US utility patents between 2015 and 2025, placing NDSU Research Foundation at rank #4,781 across all assignees tracked by PlainPatent. This portfolio spans 87 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.3 claims per patent with primary concentration in C09D (COATING COMPOSITIONS, e.g. PAINTS, VARNISHES OR LACQUERS; FILLING PASTES; CHEMICAL PAINT OR INK REMOVERS; INKS; CORRECTING FLUIDS; WOODSTAINS; PASTES OR SOLIDS FOR COLOURING OR PRINTING; USE OF MATERI). As a US Corporation, NDSU Research Foundation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, NDSU sits between Kaseya Limited (73 patents, rank #4,777) and Pride Mobility Products Corporation (73 patents, rank #4,785) - the closest US assignees by grant volume. The composite Innovation Score of 55.9/100 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 35 grants, compared with 38 in the 2015–2019 window, a -8% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. NDSU Research Foundation's 18.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 87 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark NDSU Research Foundation 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.
