What this shows Equistar's Innovation Score is 41.6/100 (top 33% 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 Equistar?

Each dot is one of Equistar’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). Equistar’s own 13.7 claims/patent is at or below the 18.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Equistar's grants concentrate

Equistar Chemicals, LP is a focused PatentsView assignee: 24 CPC subclasses with 69.2% of grants classified under C08L (Compositions OF Macromolecular Compounds). Peak complete grant year is 2016 (10 grants) versus a trough of 1 in 2024. By volume, Equistar sits between Darktrace Holdings Limited and Genethon.

Equistar's three-year grant acceleration

Equistar Chemicals, LP shows 6 grants in 2022–2024 against only 17 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.
