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 29.4 claims/patent is ABOVE the 16.4 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 Meditec Cataract Technology Inc. is a focused PatentsView assignee: 4 CPC subclasses with 100% of grants classified under A61F (Filters Implantable Into Blood VESSELS; PROSTHESES; Devices Providing Patency TO, OR Preventing Collapsing OF, Tubular Structures OF THE Body, e.g. STENTS; Orthopaedic, Nursing OR Contraceptive Device). Peak complete grant year is 2023 (9 grants) versus a trough of 1 in 2024. By volume, Carl sits between Britax Child Safety, Inc. and CF Traverse LLC.

Carl's three-year grant acceleration

Carl Zeiss Meditec Cataract Technology Inc. shows 13 grants in 2022–2024 against only 8 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.
