Does more volume mean deeper claims for Markesbery?

Each dot is one of Markesbery’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). Markesbery’s own 20.4 claims/patent is ABOVE the 14.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Markesbery's grants concentrate

Markesbery Blue Pearl LLC is a focused PatentsView assignee: 4 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 2023 (2 grants) versus a trough of 1 in 2018. By volume, Markesbery sits between Maradyne Corporation and Martin UAV, LLC.

Markesbery's three-year grant acceleration

Markesbery Blue Pearl LLC shows 3 grants in 2022–2024 against only 1 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.
