What this shows Siegfried's Innovation Score is 30.7/100 (35th percentile 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 Siegfried?

Each dot is one of Siegfried’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). Siegfried’s own 13.9 claims/patent is ABOVE the 8.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Siegfried's grants concentrate

Siegfried AG is a focused PatentsView assignee: 9 CPC subclasses with 53.8% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2016. By volume, Siegfried sits between Shenzhen Woody Vapes Technology Co., Ltd. and Simplicity, LLC.

Siegfried's three-year grant acceleration

Siegfried AG shows 2 grants in 2022–2024 against only 5 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.
