What this shows RJ's Innovation Score is 38.9/100 (top 40% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for RJ?

Each dot is one of RJ’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). RJ’s own 30.8 claims/patent is ABOVE the 12.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where RJ's grants concentrate

RJ LEE Group, Inc. is a focused PatentsView assignee: 12 CPC subclasses with 50% of grants classified under B01D (Separation). Peak complete grant year is 2020 (4 grants) versus a trough of 1 in 2016. By volume, RJ sits between Rimfrost Technologies AS and Roll-n-lock Corporation.

RJ's three-year grant acceleration

RJ LEE Group, Inc. 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.
