The verdict
22ND holds 51 US patents across 13 technology areas, rank #6,498 of 50,000 tracked assignees.
22ND Century Limited, Llc has been granted 51 US utility patents between 2015 and 2024, placing 22ND Century Limited, Llc at rank #6,498 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.9 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, 22ND Century Limited, Llc is one of the more focused assignees in the PatentsView dataset. By volume, 22ND sits between The University Court Of The University Of Glasgow (52 patents, rank #6,494) and AST & Science, Llc (51 patents, rank #6,502) - the closest US assignees by grant volume. The composite Innovation Score of 37.9/100 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 18 grants, compared with 33 in the 2015–2019 window, a -45% 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. 22ND Century Limited, Llc's 11.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark 22ND Century Limited, Llc against peers pursuing similar technology classes.

How to use this portfolio
22ND's 51 grants land it in the top 42% 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.
