What this shows Paris's Innovation Score is 62.9/100 (top 2% 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 Paris?

Each dot is one of Paris’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). Paris’s own 15.1 claims/patent is ABOVE the 11.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Paris's grants concentrate

Paris Sciences ET Lettres is a focused PatentsView assignee: 41 CPC subclasses with 16% of grants classified under B01J (Chemical OR Physical Processes, e.g. Catalysis OR Colloid CHEMISTRY; Their Relevant Apparatus). Peak complete grant year is 2024 (7 grants) versus a trough of 1 in 2021. By volume, Paris sits between Out Rage, LLC and Pizzato Elettrica S.R.L..

Paris's three-year grant acceleration

Paris Sciences ET Lettres shows 14 grants in 2022–2024 against only 1 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.
