What this shows ZS's Innovation Score is 32.4/100 (41st 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 ZS?

Each dot is one of ZS’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). ZS’s own 17.4 claims/patent is ABOVE the 12.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where ZS's grants concentrate

ZS Pharma, Inc. is a focused PatentsView assignee: 8 CPC subclasses with 100% of grants classified under C01B (Non-metallic ELEMENTS; Compounds THEREOF; ; Metalloids OR Compounds Thereof NOT Covered BY Subclass C01c). Peak complete grant year is 2017 (4 grants) versus a trough of 1 in 2016. By volume, ZS sits between Ziva Corp. and Zhejiang Topsun Logistic Control Co., Ltd..

ZS's three-year grant acceleration

ZS Pharma, Inc. shows 2 grants in 2022–2024 against only 6 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.
