What this shows IO's Innovation Score is 61.0/100 (top 3% 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 IO?
Each dot is one of IO’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). IO’s own 14.5 claims/patent is ABOVE the 8.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where IO's grants concentrate
IO Tech Group Ltd. is a focused PatentsView assignee: 29 CPC subclasses with 71.7% of grants classified under B33Y (Additive Manufacturing, i.e. Manufacturing OF Three-dimensional [3-D] Objects BY Additive Deposition, Additive Agglomeration OR Additive Layering, e.g. BY 3-D Printing, Stereolithography OR Selective ). Peak complete grant year is 2023 (12 grants) versus a trough of 2 in 2018. By volume, IO sits between Harro Hoefliger Verpackungsmaschinen GmbH and KMA Concepts Limited.
IO's three-year grant acceleration
IO Tech Group Ltd. shows 34 grants in 2022–2024 against only 8 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.
