Portfolio overview

Quadriga Biosciences, Inc. has been granted 10 US utility patents between 2016 and 2019, placing Quadriga Biosciences, Inc. at rank #27,197 across all assignees tracked by PlainPatent. This portfolio spans 6 distinct Cooperative Patent Classification (CPC) subclasses, averaging 21.5 claims per patent with primary concentration in C07F (ACYCLIC, CARBOCYCLIC OR HETEROCYCLIC COMPOUNDS CONTAINING ELEMENTS OTHER THAN CARBON, HYDROGEN, HALOGEN, OXYGEN, NITROGEN, SULFUR, SELENIUM OR TELLURIUM). As a US Corporation, Quadriga Biosciences, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Quadriga sits between QILU University OF Technology (shandong Academy OF Sciences) (10 patents, rank #27,193) and Quanticel Pharmaceuticals, Inc. (10 patents, rank #27,201) - the closest US assignees by grant volume. The composite Innovation Score of 29.8/100 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 0 grants, compared with 10 in the 2015–2019 window, a -100% 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. Quadriga Biosciences, Inc.'s 21.5 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 6 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Quadriga Biosciences, Inc. against peers pursuing similar technology classes.

How to use this portfolio

Quadriga's 10 grants land it in the top 68% by Innovation Score, but volume alone doesn't tell you where the strength sits.

  • Read that count against the largest US assignees before treating it as dominance - Quadriga ranks #27,197 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in C07F - see who else leads that technology area. C07F leaders
  • Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
