What this shows Carl's Innovation Score is 42.0/100 (top 32% 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 Carl?

Each dot is one of Carl’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). Carl’s own 16.5 claims/patent is ABOVE the 13.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Carl's grants concentrate

Carl Zeiss Vision GmbH is a focused PatentsView assignee: 17 CPC subclasses with 59.1% of grants classified under G02C (SPECTACLES; Sunglasses OR Goggles Insofar AS They Have THE Same Features AS SPECTACLES; Contact Lenses). Peak complete grant year is 2015 (6 grants) versus a trough of 1 in 2022. By volume, Carl sits between Crystal Pharmaceutical (SUZHOU) Co., Ltd. and Chongqing Ruzer Pharmaceutical Co., Ltd.

Carl's three-year grant acceleration

Carl Zeiss Vision GmbH 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.
