Does more volume mean deeper claims for Grid4c?
Each dot is one of Grid4c’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). Grid4c’s own 15.5 claims/patent is ABOVE the 13.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Grid4c's grants concentrate
Grid4c Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 66.7% of grants classified under F24F (AIR-CONDITIONING; AIR-HUMIDIFICATION; VENTILATION; USE OF AIR Currents FOR Screening). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2020. By volume, Grid4c sits between Great GO Cycles Inc. and Gripwiq Holding ApS.
Grid4c's three-year grant acceleration
Grid4c Ltd. shows 1 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.
