Does more volume mean deeper claims for Nanjing?
Each dot is one of Nanjing’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). Nanjing’s own 10.6 claims/patent is at or below the 14.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Nanjing's grants concentrate
Nanjing Qinheng Microelectronics Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 62.5% of grants classified under G06F (Electric Digital Data Processing). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2022. By volume, Nanjing sits between NABsys, 2.0 LLC and Nanoentek, Inc..
Nanjing's three-year grant acceleration
Nanjing Qinheng Microelectronics Co., Ltd. shows 5 grants in 2022–2024 against only 0 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.
