What this shows South's Innovation Score is 30.8/100 (35th percentile 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 South?

Each dot is one of South’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). South’s own 5.5 claims/patent is at or below the 16.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where South's grants concentrate

South China SEA Institute OF Oceanology, Chinese Academy OF Sciences is a focused PatentsView assignee: 18 CPC subclasses with 30.8% of grants classified under C12N (Microorganisms OR ENZYMES; Compositions THEREOF; Propagating, Preserving, OR Maintaining MICROORGANISMS; Mutation OR Genetic ENGINEERING; Culture Media). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2015. By volume, South sits between Soleras Advanced Coatings BV and Sportpet Designs, Inc..

South's three-year grant acceleration

South China SEA Institute OF Oceanology, Chinese Academy OF Sciences shows 2 grants in 2022–2024 against only 4 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.
