What this shows Preciosa's Innovation Score is 24.3/100 (14th 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 Preciosa?

Each dot is one of Preciosa’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). Preciosa’s own 7.2 claims/patent is at or below the 14.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Preciosa's grants concentrate

Preciosa, A.S. is a focused PatentsView assignee: 4 CPC subclasses with 20% of grants classified under C03C (Chemical Composition OF Glasses, Glazes OR Vitreous ENAMELS; Surface Treatment OF GLASS; Surface Treatment OF Fibres OR Filaments Made From Glass, Minerals OR SLAGS; Joining Glass TO Glass OR Other MA). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2019. By volume, Preciosa sits between Pramet Tools, S.R.O. and Premo, S.L..

Preciosa's three-year grant acceleration

Preciosa, A.S. shows 1 grants in 2022–2024 against only 1 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.
