Does more volume mean deeper claims for Estar?

Each dot is one of Estar’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). Estar’s own 8.7 claims/patent is at or below the 15.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Estar's grants concentrate

Estar Technologies Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 85.7% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2018. By volume, Estar sits between ESM ENERGIE—UND Schwingungstechnik Mitsch GMBH and Eurenco.

Estar's three-year grant acceleration

Estar Technologies 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.
