Does more volume mean deeper claims for Corplex?

Each dot is one of Corplex’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). Corplex’s own 9.5 claims/patent is ABOVE the 6.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Corplex's grants concentrate

Corplex Plastics UK Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 66.7% of grants classified under B67D (Dispensing, Delivering OR Transferring Liquids, NOT Otherwise Provided FOR). By volume, Corplex sits between Core Thermal, Inc. and Count & Crush Systems, LLC.

Corplex's three-year grant acceleration

Corplex Plastics UK Ltd. shows 2 grants in 2022–2024 against only 4 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.
