What this shows Source's Innovation Score is 39.6/100 (top 38% 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 Source?

Each dot is one of Source’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). Source’s own 20.7 claims/patent is ABOVE the 16.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Source's grants concentrate

Source Photonics (CHENGDU) Company, Ltd. is a focused PatentsView assignee: 17 CPC subclasses with 75% of grants classified under H04B (Transmission). Peak complete grant year is 2017 (8 grants) versus a trough of 1 in 2016. By volume, Source sits between SMR Inventec, LLC and STMicroelectronics France.

Source's three-year grant acceleration

Source Photonics (CHENGDU) Company, Ltd. shows 1 grants in 2022–2024 against only 13 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.
