Portfolio overview

Deregallera Holdings Ltd has been granted 9 US utility patents between 2015 and 2025, placing Deregallera Holdings Ltd at rank #28,539 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 21.7 claims per patent with primary concentration in Y02T (CLIMATE CHANGE MITIGATION TECHNOLOGIES RELATED TO TRANSPORTATION). As a Foreign Corporation, Deregallera Holdings Ltd is one of the more focused assignees in the PatentsView dataset. By volume, Deregallera sits between Delta Scientific Corporation (9 patents, rank #28,535) and Diffusion Pharmaceuticals Llc (9 patents, rank #28,543) - the closest US assignees by grant volume. The composite Innovation Score of 47.5/100 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. Between 2020 and 2025 the company received 4 grants, compared with 5 in the 2015–2019 window, a -20% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The Foreign 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. Deregallera Holdings Ltd's 21.7 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 14 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Deregallera Holdings Ltd against peers pursuing similar technology classes.

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.
