Does more volume mean deeper claims for Spreadtrum?

Each dot is one of Spreadtrum’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). Spreadtrum’s own 18.6 claims/patent is ABOVE the 16.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Spreadtrum's grants concentrate

Spreadtrum Semiconductor (NANJING) Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 88.9% of grants classified under H04W (Wireless Communication Networks). By volume, Spreadtrum sits between Spdi Holdings, Inc. and Stabila Messgeräte Gustav Ullrich GmbH.

Spreadtrum's three-year grant acceleration

Spreadtrum Semiconductor (NANJING) Co., Ltd. shows 2 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.
