What this shows Leadway's Innovation Score is 36.6/100 (top 46% 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 Leadway?

Each dot is one of Leadway’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). Leadway’s own 8.1 claims/patent is ABOVE the 3.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Leadway's grants concentrate

Leadway (HK) Limited is a focused PatentsView assignee: 20 CPC subclasses with 68.2% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2020 (5 grants) versus a trough of 1 in 2021. By volume, Leadway sits between KÖRBER Technologies GMBH and Luoyang Dbin Office Furniture Co., Ltd..

Leadway's three-year grant acceleration

Leadway (HK) Limited shows 7 grants in 2022–2024 against only 9 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.
