Does more volume mean deeper claims for Grena?

Each dot is one of Grena’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). Grena’s own 19.1 claims/patent is ABOVE the 16.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Grena's grants concentrate

Grena USA LLC is a focused PatentsView assignee: 1 CPC subclasses with 100% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2019. By volume, Grena sits between Green Biologics Limited and Grirem Hi-tech Co., Ltd..

Grena's three-year grant acceleration

Grena USA LLC shows 3 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.
