Does more volume mean deeper claims for Sandora?

Each dot is one of Sandora’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). Sandora’s own 9.6 claims/patent is at or below the 10.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Sandora's grants concentrate

Sandora Household Electric Appliances (SHENZHEN) Ltd is a focused PatentsView assignee: 4 CPC subclasses with 85.7% of grants classified under A47J (Kitchen EQUIPMENT; Coffee MILLS; Spice MILLS; Apparatus FOR Making Beverages). Peak complete grant year is 2024 (4 grants) versus a trough of 1 in 2020. By volume, Sandora sits between Samsung Total Petrochemicals Co., Ltd. and Santos.

Sandora's three-year grant acceleration

Sandora Household Electric Appliances (SHENZHEN) Ltd shows 6 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.
