What this shows Shield's Innovation Score is 37.8/100 (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 Shield?

Each dot is one of Shield’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). Shield’s own 13.3 claims/patent is ABOVE the 5.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Shield's grants concentrate

Shield Corporation Limited is a focused PatentsView assignee: 7 CPC subclasses with 28.6% of grants classified under F41G (Weapon SIGHTS; Aiming). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2016. By volume, Shield sits between Shenzhen Yangwo Electronic Co., Ltd. and Shooting Simulator, LLC.

Shield's three-year grant acceleration

Shield Corporation Limited shows 2 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.
