What this shows Occidental's Innovation Score is 35.0/100 (top 50% 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 Occidental?

Each dot is one of Occidental’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). Occidental’s own 15.3 claims/patent is at or below the 15.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Occidental's grants concentrate

Occidental Chemical Corporation is a focused PatentsView assignee: 8 CPC subclasses with 95.5% of grants classified under C07C (Acyclic OR Carbocyclic Compounds). Peak complete grant year is 2020 (6 grants) versus a trough of 1 in 2019. By volume, Occidental sits between Orcan Energy AG and OpenAI OpCo, LLC.

Occidental's three-year grant acceleration

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