Portfolio overview

ZOLL Medical Corporation has been granted 740 US utility patents between 2015 and 2025, placing ZOLL Medical Corporation at rank #599 across all assignees tracked by PlainPatent. This portfolio spans 60 distinct Cooperative Patent Classification (CPC) subclasses, averaging 24.4 claims per patent with primary concentration in A61N (ELECTROTHERAPY; MAGNETOTHERAPY; RADIATION THERAPY; ULTRASOUND THERAPY). As a US Corporation, ZOLL Medical Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, ZOLL sits between The Toronto-dominion Bank (748 patents, rank #595) and Seminis Vegetable Seeds, Inc. (735 patents, rank #603) - the closest US assignees by grant volume. The composite Innovation Score of 69.0/100 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 451 grants, compared with 289 in the 2015–2019 window, a +56% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. ZOLL Medical Corporation's 24.4 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while a multi-domain presence across 60 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark ZOLL Medical Corporation 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.
