What this shows Nanjing's Innovation Score is 46.5/100 (top 21% 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 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 14.3 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 Nanjing's grants concentrate

Nanjing Greenchip Semiconductor Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 66.7% of grants classified under Y02B (Climate Change Mitigation Technologies Related TO Buildings, e.g. Housing, House Appliances OR Related End-user Applications). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2019. By volume, Nanjing sits between Nabors Drilling USA, LP and Nano Hesgarsazan Salamat Arya.

Nanjing's three-year grant acceleration

Nanjing Greenchip Semiconductor Co., Ltd. shows 3 grants in 2022–2024 against only 1 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.
