What this shows Ceramtec's Innovation Score is 47.8/100 (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 Ceramtec?

Each dot is one of Ceramtec’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). Ceramtec’s own 13.3 claims/patent is at or below the 17.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Ceramtec's grants concentrate

Ceramtec GMBH is a focused PatentsView assignee: 42 CPC subclasses with 35.6% of grants classified under C04B (Lime, MAGNESIA; SLAG; CEMENTS; Compositions Thereof, e.g. Mortars, Concrete OR Like Building MATERIALS; Artificial Stone ; Ceramics ; REFRACTORIES; Treatment OF Natural Stone). Peak complete grant year is 2016 (14 grants) versus a trough of 1 in 2023. By volume, Ceramtec sits between BP Exploration Operating Company Limited and Contitech Transportbandsysteme GmBH.

Ceramtec's three-year grant acceleration

Ceramtec GMBH shows 5 grants in 2022–2024 against only 12 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.
