Does more volume mean deeper claims for Coretrax?
Each dot is one of Coretrax’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). Coretrax’s own 11.8 claims/patent is at or below the 18.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Coretrax's grants concentrate
Coretrax Americas Ltd. is a focused PatentsView assignee: 2 CPC subclasses with 100% of grants classified under E21B (Earth OR Rock DRILLING; Obtaining OIL, GAS, Water, Soluble OR Meltable Materials OR A Slurry OF Minerals From Wells). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2024. By volume, Coretrax sits between Copeland Europe GmbH and Cotiviti, Inc..
Coretrax's three-year grant acceleration
Coretrax Americas Ltd. shows 7 grants in 2022–2024 against only 0 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.
