What this shows Cellmax's Innovation Score is 29.4/100 (31st percentile 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 Cellmax?

Each dot is one of Cellmax’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). Cellmax’s own 20.0 claims/patent is ABOVE the 11.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Cellmax's grants concentrate

Cellmax Technologies AB is a focused PatentsView assignee: 3 CPC subclasses with 100% of grants classified under H01Q (Antennas, i.e. Radio Aerials). Peak complete grant year is 2019 (4 grants) versus a trough of 1 in 2016. By volume, Cellmax sits between Carter-hoffmann LLC and Chugoku Marine Paints, Ltd..

Cellmax's three-year grant acceleration

Cellmax Technologies AB shows 2 grants in 2022–2024 against only 10 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.
