What this shows Zalman's Innovation Score is 44.6/100 (top 25% 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 Zalman?

Each dot is one of Zalman’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). Zalman’s own 4.2 claims/patent is at or below the 13.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Zalman's grants concentrate

Zalman Tech Co., Ltd. is a focused PatentsView assignee: 14 CPC subclasses with 25% 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 2016 (8 grants) versus a trough of 1 in 2015. By volume, Zalman sits between Yagi Corp. and Zhangzhou GO WIN Lighting Co., Ltd.

Zalman's three-year grant acceleration

Zalman Tech Co., Ltd. shows 3 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.
