What this shows Duralchrome's Innovation Score is 44.5/100 (top 26% 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 Duralchrome?

Each dot is one of Duralchrome’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). Duralchrome’s own 16.0 claims/patent is ABOVE the 13.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Duralchrome's grants concentrate

Duralchrome AG is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under B41C (Processes FOR THE Manufacture OR Reproduction OF Printing Surfaces). Peak complete grant year is 2024 (2 grants) versus a trough of 1 in 2022. By volume, Duralchrome sits between DUN & Bradstreet Emerging Businesses Corp. and Dvdcase, Inc..

Duralchrome's three-year grant acceleration

Duralchrome AG shows 4 grants in 2022–2024 against only 0 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.
