Does more volume mean deeper claims for Hefei?
Each dot is one of Hefei’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). Hefei’s own 1.0 claims/patent is at or below the 9.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Hefei's grants concentrate
Hefei Tuwa Technology Co., Ltd. is a focused PatentsView assignee: 0 CPC subclasses . Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2024. By volume, Hefei sits between Hearth Products Controls Co. and Helion Biotech ApS.
Hefei's three-year grant acceleration
Hefei Tuwa Technology Co., Ltd. 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.
