What this shows Hannstar's Innovation Score is 38.9/100 (top 40% 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 Hannstar?

Each dot is one of Hannstar’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). Hannstar’s own 14.9 claims/patent is at or below the 15.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Hannstar's grants concentrate

HannStar Display (Nanjing) Corporation is a focused PatentsView assignee: 20 CPC subclasses with 43.6% of grants classified under G06F (Electric Digital Data Processing). Peak complete grant year is 2017 (10 grants) versus a trough of 1 in 2015. By volume, Hannstar sits between Gooee Limited and IML International.

Hannstar's three-year grant acceleration

HannStar Display (Nanjing) Corporation shows 3 grants in 2022–2024 against only 15 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.
