What this shows Siemens's Innovation Score is 47.5/100 (top 18% 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 15.2 claims/patent is ABOVE the 12.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Siemens's grants concentrate

Siemens Canada Limited is a focused PatentsView assignee: 37 CPC subclasses with 33.3% of grants classified under H04L (Transmission OF Digital Information, e.g. Telegraphic Communication). Peak complete grant year is 2019 (5 grants) versus a trough of 1 in 2016. By volume, Siemens sits between Scuola Superiore di Studi Universitari e di Perfezionamento Sant'Anna and Sky CP Limited.

Siemens's three-year grant acceleration

Siemens Canada Limited shows 8 grants in 2022–2024 against only 10 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.
