What this shows Pujiang's Innovation Score is 45.6/100 (top 23% 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 Pujiang?

Each dot is one of Pujiang’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). Pujiang’s own 8.4 claims/patent is at or below the 16.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Pujiang's grants concentrate

Pujiang Sansi Optoelectronic Technology Co. Ltd. is a focused PatentsView assignee: 12 CPC subclasses with 70% of grants classified under F21Y (Indexing Scheme Associated With Subclasses F21k, F21l, F21s and F21v, Relating TO THE Form OR THE Kind OF THE Light Sources OR OF THE Colour OF THE Light Emitted). Peak complete grant year is 2023 (5 grants) versus a trough of 2 in 2024. By volume, Pujiang sits between Prostar Energy Technologies (USA) LLC and Qilu University OF Technology (SHANDONG Academy OF SCIENCES).

Pujiang's three-year grant acceleration

Pujiang Sansi Optoelectronic Technology Co. Ltd. shows 10 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.
