What this shows Alfdex's Innovation Score is 30.7/100 (35th 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 Alfdex?

Each dot is one of Alfdex’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). Alfdex’s own 16.1 claims/patent is ABOVE the 15.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Alfdex's grants concentrate

Alfdex AB is a focused PatentsView assignee: 3 CPC subclasses with 80% of grants classified under F01M (Lubricating OF Machines OR Engines IN GENERAL; Lubricating Internal Combustion ENGINES; Crankcase Ventilating). Peak complete grant year is 2021 (3 grants) versus a trough of 2 in 2016. By volume, Alfdex sits between AKWEL and Allen-vanguard Corporation.

Alfdex's three-year grant acceleration

Alfdex AB shows 3 grants in 2022–2024 against only 3 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.
