What this shows Siempelkamp's Innovation Score is 47.0/100 (top 19% 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.

Where Siempelkamp's grants concentrate

Siempelkamp Maschinen- und Anlagenbau GmbH is a focused PatentsView assignee: 23 CPC subclasses with 42.1% of grants classified under B29C (Shaping OR Joining OF PLASTICS; Shaping OF Material IN A Plastic State, NOT Otherwise Provided FOR; After-treatment OF THE Shaped Products, e.g. Repairing). Peak complete grant year is 2024 (4 grants) versus a trough of 1 in 2015. By volume, Siempelkamp sits between Shenzhen Dongjilian Medical Tech Co., Ltd and Skytap.

Siempelkamp's three-year grant acceleration

Siempelkamp Maschinen- und Anlagenbau GmbH shows 7 grants in 2022–2024 against only 4 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.
