What this shows 4D's Innovation Score is 47.1/100 (top 19% 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 4D?

Each dot is one of 4D’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). 4D’s own 18.9 claims/patent is ABOVE the 13.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where 4D's grants concentrate

4D Molecular Therapeutics Inc. is a focused PatentsView assignee: 5 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). Peak complete grant year is 2022 (6 grants) versus a trough of 4 in 2021. By volume, 4D sits between iStreamPlanet Co., LLC and Academy OF Shenzhen Guohua Optoelectronics.

4D's three-year grant acceleration

4D Molecular Therapeutics Inc. shows 11 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.
