What this shows Spark's Innovation Score is 39.5/100 (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 Spark?

Each dot is one of Spark’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). Spark’s own 40.3 claims/patent is ABOVE the 10.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Spark's grants concentrate

Spark Therapeutics, Inc. is a focused PatentsView assignee: 9 CPC subclasses with 100% of grants classified under C12N (Microorganisms OR ENZYMES; Compositions THEREOF; Propagating, Preserving, OR Maintaining MICROORGANISMS; Mutation OR Genetic ENGINEERING; Culture Media). By volume, Spark sits between Southern Plant Group, LLC and Speaqua Corporation.

Spark's three-year grant acceleration

Spark Therapeutics, Inc. shows 2 grants in 2022–2024 against only 2 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.
