What this shows Guangdong's Innovation Score is 36.2/100 (top 47% 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 Guangdong?

Each dot is one of Guangdong’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). Guangdong’s own 8.7 claims/patent is at or below the 15.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Guangdong's grants concentrate

Guangdong Sirui Optical Co., Ltd. is a focused PatentsView assignee: 15 CPC subclasses with 30.3% of grants classified under G03B (Apparatus OR Arrangements FOR Taking Photographs OR FOR Projecting OR Viewing THEM; Apparatus OR Arrangements Employing Analogous Techniques Using Waves Other Than Optical WAVES; Accessories Therefor). Peak complete grant year is 2020 (7 grants) versus a trough of 3 in 2019. By volume, Guangdong sits between Ginkgo Bioworks, Inc. and Haver & Boecker OHG.

Guangdong's three-year grant acceleration

Guangdong Sirui Optical Co., Ltd. shows 13 grants in 2022–2024 against only 17 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.
