Does more volume mean deeper claims for Refai?

Each dot is one of Refai’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). Refai’s own 13.8 claims/patent is at or below the 18.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Refai's grants concentrate

Refai Technologies, L.L.C. is a focused PatentsView assignee: 3 CPC subclasses with 76.9% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2016. By volume, Refai sits between Raval A.C.S. Ltd. and Restek Corporation.

Refai's three-year grant acceleration

Refai Technologies, L.L.C. shows 6 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.
