Does more volume mean deeper claims for Tongfu?
Each dot is one of Tongfu’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). Tongfu’s own 14.4 claims/patent is ABOVE the 11.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Tongfu's grants concentrate
Tongfu Microelectronics Co., Ltd. is a focused PatentsView assignee: 3 CPC subclasses with 75.9% of grants classified under H01L (Semiconductor Devices NOT Covered BY Class H10). Peak complete grant year is 2018 (7 grants) versus a trough of 1 in 2019. By volume, Tongfu sits between Tenable, Inc. and Turck Holding GmbH.
Tongfu's three-year grant acceleration
Tongfu Microelectronics Co., Ltd. shows 9 grants in 2022–2024 against only 8 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.
