What this shows Viessmann's Innovation Score is 33.1/100 (43rd 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 Viessmann?

Each dot is one of Viessmann’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). Viessmann’s own 10.9 claims/patent is at or below the 15.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Viessmann's grants concentrate

Viessmann Werke GMBH & Co. KG is a focused PatentsView assignee: 19 CPC subclasses with 42.9% of grants classified under Y02B (Climate Change Mitigation Technologies Related TO Buildings, e.g. Housing, House Appliances OR Related End-user Applications). Peak complete grant year is 2020 (7 grants) versus a trough of 2 in 2019. By volume, Viessmann sits between Vaon, LLC and VOIP-PAL.COM, Inc..

Viessmann's three-year grant acceleration

Viessmann Werke GMBH & Co. KG shows 3 grants in 2022–2024 against only 11 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.
