What this shows Norbrook's Innovation Score is 44.2/100 (top 26% 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 Norbrook?

Each dot is one of Norbrook’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). Norbrook’s own 15.2 claims/patent is ABOVE the 13.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Norbrook's grants concentrate

Norbrook Laboratories Limited is a focused PatentsView assignee: 4 CPC subclasses with 88.9% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2016 (3 grants) versus a trough of 1 in 2015. By volume, Norbrook sits between Nippon Yttrium Co., Ltd. and Novartis Tiergesundheit AG.

Norbrook's three-year grant acceleration

Norbrook Laboratories Limited shows 3 grants in 2022–2024 against only 1 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.
