Portfolio overview

Delavan Inc. has been granted 180 US utility patents between 2015 and 2025, placing Delavan Inc. at rank #2,181 across all assignees tracked by PlainPatent. This portfolio spans 70 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.1 claims per patent with primary concentration in F23R (GENERATING COMBUSTION PRODUCTS OF HIGH PRESSURE OR HIGH VELOCITY, e.g. GAS-TURBINE COMBUSTION CHAMBERS). As a US Corporation, Delavan Inc. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Delavan sits between 3shape A/s (180 patents, rank #2,177) and Olympus Medical Systems Corporation (180 patents, rank #2,185) - the closest US assignees by grant volume. The composite Innovation Score of 52.6/100 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 92 grants, compared with 88 in the 2015–2019 window, a +5% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Delavan Inc.'s 13.1 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 70 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Delavan Inc. 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.
