What this shows Albemarle's Innovation Score is 28.8/100 (29th 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 Albemarle?

Each dot is one of Albemarle’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). Albemarle’s own 14.2 claims/patent is at or below the 15.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Albemarle's grants concentrate

Albemarle Europe SRL is a focused PatentsView assignee: 5 CPC subclasses with 100% of grants classified under B01J (Chemical OR Physical Processes, e.g. Catalysis OR Colloid CHEMISTRY; Their Relevant Apparatus). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2015. By volume, Albemarle sits between Aisin Fukui Corporation and Alfred E. Tiefenbacher (GMBH & Co. KG).

Albemarle's three-year grant acceleration

Albemarle Europe SRL shows 2 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.
