Portfolio overview
Hothouse Medical Limited has been granted 6 US utility patents between 2021 and 2024, placing Hothouse Medical Limited at rank #40,772 across all assignees tracked by PlainPatent. This portfolio spans 2 distinct Cooperative Patent Classification (CPC) subclasses, averaging 34.8 claims per patent with primary concentration in A61L (METHODS OR APPARATUS FOR STERILISING MATERIALS OR OBJECTS IN GENERAL; DISINFECTION, STERILISATION OR DEODORISATION OF AIR; CHEMICAL ASPECTS OF BANDAGES, DRESSINGS, ABSORBENT PADS OR SURGICAL ARTICLES;). As a Foreign Corporation, Hothouse Medical Limited is one of the more focused assignees in the PatentsView dataset. By volume, Hothouse sits between Hoosier Energy Rural Electric Cooperative, Inc. (6 patents, rank #40,768) and Hugh Steeper Limited (6 patents, rank #40,776) - the closest US assignees by grant volume. The composite Innovation Score of 33.4/100 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. Historical data spans 2021 through 2024, with 6 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Hothouse Medical Limited's 34.8 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while specialization in 2 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Hothouse Medical Limited against peers pursuing similar technology classes.
