What this shows Green's Innovation Score is 38.3/100 (top 41% 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 Green?

Each dot is one of Green’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). Green’s own 13.7 claims/patent is ABOVE the 8.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Green's grants concentrate

Green Refrigeration Equipment Engineering Research Center OF Zhuhai Gree Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 64.3% of grants classified under F04C (Rotary-piston, OR Oscillating-piston, Positive-displacement Machines FOR Liquids ; Rotary-piston, OR Oscillating-piston, Positive-displacement Pumps). Peak complete grant year is 2022 (5 grants) versus a trough of 1 in 2017. By volume, Green sits between Good T Cells, Inc. and Guangzhou Seagull Kitchen AND Bath Products Co., Ltd..

Green's three-year grant acceleration

Green Refrigeration Equipment Engineering Research Center OF Zhuhai Gree Co., Ltd. shows 8 grants in 2022–2024 against only 5 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.
