What this shows Guardian'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 Guardian?

Each dot is one of Guardian’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). Guardian’s own 18.6 claims/patent is ABOVE the 10.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Guardian's grants concentrate

Guardian Optical Technologies, Ltd. is a focused PatentsView assignee: 9 CPC subclasses with 80% of grants classified under G06T (Image Data Processing OR Generation, IN General). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2021. By volume, Guardian sits between Guangzhou Medical University and Gutschsemi Limited.

Guardian's three-year grant acceleration

Guardian Optical Technologies, Ltd. shows 2 grants in 2022–2024 against only 3 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.
