Portfolio overview

Delfortgroup Ag has been granted 24 US utility patents between 2015 and 2025, placing Delfortgroup Ag at rank #12,403 across all assignees tracked by PlainPatent. This portfolio spans 12 distinct Cooperative Patent Classification (CPC) subclasses, averaging 25.4 claims per patent with primary concentration in D21H (PULP COMPOSITIONS; PREPARATION THEREOF NOT COVERED BY SUBCLASSES D21C OR D21D; IMPREGNATING OR COATING OF PAPER; TREATMENT OF FINISHED PAPER NOT COVERED BY CLASS B31 OR SUBCLASS D21G; PAPER NOT OTHERW). As a Foreign Corporation, Delfortgroup Ag is one of the more focused assignees in the PatentsView dataset. By volume, Delfortgroup sits between Cyclerion Therapeutics, Inc. (24 patents, rank #12,399) and Digitalinsights Inc. (24 patents, rank #12,407) - the closest US assignees by grant volume. The composite Innovation Score of 40.9/100 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 7 grants, compared with 17 in the 2015–2019 window, a -59% 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. Delfortgroup Ag's 25.4 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 12 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Delfortgroup Ag 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.
