What this shows Siemens's Innovation Score is 41.3/100 (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 Siemens?

Each dot is one of Siemens’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). Siemens’s own 16.0 claims/patent is at or below the 16.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Siemens's grants concentrate

Siemens S.A.S is a focused PatentsView assignee: 21 CPC subclasses with 33.3% of grants classified under B61L (Guiding Railway TRAFFIC; Ensuring THE Safety OF Railway Traffic). Peak complete grant year is 2016 (6 grants) versus a trough of 1 in 2015. By volume, Siemens sits between Shenzhen Kimsen Technology Co., Ltd and Silergy Corp..

Siemens's three-year grant acceleration

Siemens S.A.S shows 1 grants in 2022–2024 against only 0 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.
