USPTO PatentsView assignee record - 39 granted patents across 13 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
Cydex holds 39 US patents across 13 technology areas, rank #8,184 of 50,000 tracked assignees.
Cydex Pharmaceuticals, Inc. has been granted 39 US utility patents between 2015 and 2025, placing Cydex Pharmaceuticals, Inc. at rank #8,184 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 24.5 claims per patent with primary concentration in A61K (PREPARATIONS FOR MEDICAL, DENTAL OR TOILETRY PURPOSES). As a US Corporation, Cydex Pharmaceuticals, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Cydex sits between Cayenne Medical, Inc. (39 patents, rank #8,180) and Deep Science, Llc (39 patents, rank #8,188) - the closest US assignees by grant volume. The composite Innovation Score of 42.2/100 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 19 grants, compared with 20 in the 2015–2019 window, a -5% 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. Cydex Pharmaceuticals, Inc.'s 24.5 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Cydex Pharmaceuticals, Inc. against peers pursuing similar technology classes.

How to use this portfolio
Cydex's 39 grants land it in the top 31% 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.
