What this shows SMH's Innovation Score is 31.3/100 (37th 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 SMH?

Each dot is one of SMH’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). SMH’s own 18.2 claims/patent is ABOVE the 16.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where SMH's grants concentrate

SMH Co., Ltd is a focused PatentsView assignee: 4 CPC subclasses with 100% of grants classified under B01J (Chemical OR Physical Processes, e.g. Catalysis OR Colloid CHEMISTRY; Their Relevant Apparatus). Peak complete grant year is 2019 (4 grants) versus a trough of 1 in 2021. By volume, SMH sits between Slim HMI Technology and Sodyo Ltd..

SMH's three-year grant acceleration

SMH Co., Ltd shows 4 grants in 2022–2024 against only 5 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.
