Does more volume mean deeper claims for Hong?

Each dot is one of Hong’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). Hong’s own 5.3 claims/patent is at or below the 11.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Hong's three-year grant acceleration

Hong Kong Wudi International Trading Co., Limited shows 3 grants in 2022–2024 against only 0 in 2019–2021.
