What this shows Ghangxin's Innovation Score is 42.9/100 (top 30% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Ghangxin?

Each dot is one of Ghangxin’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). Ghangxin’s own 14.6 claims/patent is ABOVE the 11.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Ghangxin's grants concentrate

Ghangxin Memory Technologies, Inc. is a focused PatentsView assignee: 5 CPC subclasses with 60% of grants classified under H01L (Semiconductor Devices NOT Covered BY Class H10). Peak complete grant year is 2023 (4 grants) versus a trough of 1 in 2022. By volume, Ghangxin sits between Gesa Form + Funktion Displaybau GmbH and Gibaud.

Ghangxin's three-year grant acceleration

Ghangxin Memory Technologies, Inc. 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.
