What this shows Alkon's Innovation Score is 46.7/100 (top 20% 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 Alkon?

Each dot is one of Alkon’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). Alkon’s own 18.7 claims/patent is ABOVE the 17.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Alkon's grants concentrate

Alkon Corporation is a focused PatentsView assignee: 21 CPC subclasses with 68.4% of grants classified under B28C (Preparing CLAY; Producing Mixtures Containing Clay OR Cementitious Material, e.g. Plaster). Peak complete grant year is 2022 (6 grants) versus a trough of 1 in 2016. By volume, Alkon sits between AiBUY, Inc. and America Covers, Inc..

Alkon's three-year grant acceleration

Alkon Corporation shows 8 grants in 2022–2024 against only 6 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.
