Portfolio overview
Windtree Therapeutics, Inc. has been granted 6 US utility patents between 2016 and 2025, placing Windtree Therapeutics, Inc. at rank #44,085 across all assignees tracked by PlainPatent. This portfolio spans 5 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.5 claims per patent with primary concentration in A61P (SPECIFIC THERAPEUTIC ACTIVITY OF CHEMICAL COMPOUNDS OR MEDICINAL PREPARATIONS). As a US Corporation, Windtree Therapeutics, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Windtree sits between Wildlife Research Center, Inc. (6 patents, rank #44,081) and Wohner Gmbh & Co. KG Elektrotechnische Systeme (6 patents, rank #44,089) - the closest US assignees by grant volume. The composite Innovation Score of 31.8/100 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 3 grants, compared with 3 in the 2015–2019 window, a +0% 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. Windtree Therapeutics, Inc.'s 17.5 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 Windtree Therapeutics, Inc. against peers pursuing similar technology classes.
