What this shows Sigma-aldrich's Innovation Score is 49.0/100 (top 16% 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 Sigma-aldrich?

Each dot is one of Sigma-aldrich’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). Sigma-aldrich’s own 13.2 claims/patent is at or below the 16.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Sigma-aldrich's grants concentrate

Sigma-Aldrich Co. LLC is a focused PatentsView assignee: 32 CPC subclasses with 53.6% of grants classified under C12N (Microorganisms OR ENZYMES; Compositions THEREOF; Propagating, Preserving, OR Maintaining MICROORGANISMS; Mutation OR Genetic ENGINEERING; Culture Media). Peak complete grant year is 2015 (10 grants) versus a trough of 2 in 2017. By volume, Sigma-aldrich sits between Shenzhen Xunweijia Technology Development Co., Ltd. and TQ Delta, LLC.

Sigma-aldrich's three-year grant acceleration

Sigma-Aldrich Co. LLC shows 17 grants in 2022–2024 against only 16 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.
