What this shows Azotek's Innovation Score is 36.4/100 (top 47% 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 Azotek?

Each dot is one of Azotek’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). Azotek’s own 10.5 claims/patent is at or below the 18.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Azotek's grants concentrate

Azotek Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 80% of grants classified under H05K (Printed CIRCUITS; Casings OR Constructional Details OF Electric APPARATUS; Manufacture OF Assemblages OF Electrical Components). Peak complete grant year is 2022 (4 grants) versus a trough of 1 in 2016. By volume, Azotek sits between Avient Protective Materials B.V. and ActLight SA.

Azotek's three-year grant acceleration

Azotek Co., Ltd. shows 7 grants in 2022–2024 against only 5 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.
