What this shows Amscreen's Innovation Score is 34.9/100 (49th 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 Amscreen?

Each dot is one of Amscreen’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). Amscreen’s own 24.7 claims/patent is ABOVE the 15.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Amscreen's grants concentrate

Amscreen Group Limited is a focused PatentsView assignee: 8 CPC subclasses with 83.3% of grants classified under G02F (Optical Devices OR Arrangements FOR THE Control OF Light BY Modification OF THE Optical Properties OF THE Media OF THE Elements Involved THEREIN; Non-linear OPTICS; Frequency-changing OF LIGHT; Optica). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2020. By volume, Amscreen sits between Ampacet Corporation and ANB Sensors Ltd.

Amscreen's three-year grant acceleration

Amscreen Group Limited shows 2 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.
