Does more volume mean deeper claims for Hothouse?
Each dot is one of Hothouse’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Hothouse’s own 34.8 claims/patent is ABOVE the 13.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Hothouse's grants concentrate
Hothouse Medical Limited is a focused PatentsView assignee: 2 CPC subclasses with 100% of grants classified under 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;). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2024. By volume, Hothouse sits between Hoosier Energy Rural Electric Cooperative, Inc. and Hugh Steeper Limited.
Hothouse's three-year grant acceleration
Hothouse Medical Limited shows 3 grants in 2022–2024 against only 3 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
