USPTO PatentsView assignee record - 10 granted patents across 5 technology areas, active 2022–2025. 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
Nivagen holds 10 US patents across 5 technology areas, rank #26,990 of 50,000 tracked assignees.
Nivagen Pharmaceuticals, Inc. has been granted 10 US utility patents between 2022 and 2025, placing Nivagen Pharmaceuticals, Inc. at rank #26,990 across all assignees tracked by PlainPatent. This portfolio spans 5 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.2 claims per patent with primary concentration in A61K (PREPARATIONS FOR MEDICAL, DENTAL OR TOILETRY PURPOSES). As a US Corporation, Nivagen Pharmaceuticals, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Nivagen sits between Ningbo Qisen Technology Co., Ltd (10 patents, rank #26,986) and Nothing Technology Limited (10 patents, rank #26,994) - the closest US assignees by grant volume. The composite Innovation Score of 46.5/100 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. Historical data spans 2022 through 2025, with 10 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Nivagen Pharmaceuticals, Inc.'s 17.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 5 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Nivagen Pharmaceuticals, Inc. against peers pursuing similar technology classes.

How to use this portfolio
Nivagen's 10 grants land it in the top 21% 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.
