What this shows Qioptiq's Innovation Score is 38.1/100 (top 42% 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 Qioptiq?

Each dot is one of Qioptiq’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). Qioptiq’s own 18.6 claims/patent is ABOVE the 15.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Qioptiq's grants concentrate

Qioptiq Limited is a focused PatentsView assignee: 16 CPC subclasses with 68.4% of grants classified under G02B (Optical Elements, Systems OR Apparatus). Peak complete grant year is 2019 (6 grants) versus a trough of 1 in 2015. By volume, Qioptiq sits between QC Ware Corp. and RTI Surgical, Inc..

Qioptiq's three-year grant acceleration

Qioptiq Limited shows 4 grants in 2022–2024 against only 11 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.
