What this shows Memsstar's Innovation Score is 25.0/100 (16th 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 Memsstar?

Each dot is one of Memsstar’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). Memsstar’s own 14.0 claims/patent is ABOVE the 12.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Memsstar's grants concentrate

Memsstar Limited is a focused PatentsView assignee: 4 CPC subclasses with 100% of grants classified under H01L (Semiconductor Devices NOT Covered BY Class H10). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2017. By volume, Memsstar sits between Memblaze Technology (BEIJING) Co., Ltd. and Mercer (US) Inc..

Memsstar's three-year grant acceleration

Memsstar Limited shows 1 grants in 2022–2024 against only 2 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.
