What this shows Zedsen's Innovation Score is 35.5/100 (top 49% 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 Zedsen?

Each dot is one of Zedsen’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). Zedsen’s own 17.5 claims/patent is ABOVE the 10.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Zedsen's grants concentrate

Zedsen Limited is a focused PatentsView assignee: 8 CPC subclasses with 60% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2022 (4 grants) versus a trough of 1 in 2023. By volume, Zedsen sits between Zahner Design Group, Ltd. and Zhangjiagang SMK MFG. Co., Ltd..

Zedsen's three-year grant acceleration

Zedsen Limited shows 5 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.
