What this shows Cejn's Innovation Score is 32.5/100 (41st 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 Cejn?

Each dot is one of Cejn’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). Cejn’s own 14.7 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 Cejn's grants concentrate

Cejn AB is a focused PatentsView assignee: 11 CPC subclasses with 90.9% of grants classified under F16L (PIPES; Joints OR Fittings FOR PIPES; Supports FOR Pipes, Cables OR Protective TUBING; Means FOR Thermal Insulation IN General). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2016. By volume, Cejn sits between Cardiologs Technologies SAS and Chad Dorsey Design, LLC.

Cejn's three-year grant acceleration

Cejn AB 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.
