What this shows Donaghys's Innovation Score is 51.1/100 (top 12% 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 Donaghys?

Each dot is one of Donaghys’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). Donaghys’s own 20.6 claims/patent is ABOVE the 1.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Donaghys's grants concentrate

Donaghys Limited is a focused PatentsView assignee: 10 CPC subclasses with 75% of grants classified under A01N (Preservation OF Bodies OF Humans OR Animals OR Plants OR Parts Thereof ; Biocides, e.g. AS Disinfectants, AS Pesticides OR AS Herbicides ; Pest Repellants OR ATTRACTANTS; Plant Growth Regulators). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2015. By volume, Donaghys sits between DigitalOptometrics LLC and Dongguan Jierui Sports Goods Co., Ltd..

Donaghys's three-year grant acceleration

Donaghys Limited shows 4 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.
