USPTO PatentsView assignee record - 5 granted patents across 4 technology areas, active 2016–2021. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: C12N (MICROORGANISMS OR ENZYMES; COMPOSITIONS THEREOF; PROPAGATING, PRESERVING, OR MAINTAINING MICROORGANISMS; MUTATION OR GENETIC ENGINEERING; CULTURE MEDIA).
The verdict
National holds 5 US patents across 4 technology areas, rank #48,964 of 50,000 tracked assignees.
National Institute OF Transplantation Foundation has been granted 5 US utility patents between 2016 and 2021, placing National Institute OF Transplantation Foundation at rank #48,964 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 20.8 claims per patent with primary concentration in C12N (MICROORGANISMS OR ENZYMES; COMPOSITIONS THEREOF; PROPAGATING, PRESERVING, OR MAINTAINING MICROORGANISMS; MUTATION OR GENETIC ENGINEERING; CULTURE MEDIA). As a US Corporation, National Institute OF Transplantation Foundation is one of the more focused assignees in the PatentsView dataset. By volume, National sits between NATI Brook Ventures, Llc (5 patents, rank #48,960) and National University Corporation (5 patents, rank #48,968) - the closest US assignees by grant volume. The composite Innovation Score of 25.7/100 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 2 grants, compared with 3 in the 2015–2019 window, a -33% 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. National Institute OF Transplantation Foundation's 20.8 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while specialization in 4 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark National Institute OF Transplantation Foundation against peers pursuing similar technology classes.

How to use this portfolio
National's 5 grants land it in the top 82% 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.
