Does more volume mean deeper claims for Stefan?
Each dot is one of Stefan’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). Stefan’s own 14.5 claims/patent is ABOVE the 11.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Stefan's grants concentrate
Stefan Pfaff Werkzeug- UND Formenbau GMBH & Co KG is a focused PatentsView assignee: 9 CPC subclasses with 83.3% of grants classified under B29C (Shaping OR Joining OF PLASTICS; Shaping OF Material IN A Plastic State, NOT Otherwise Provided FOR; After-treatment OF THE Shaped Products, e.g. Repairing). Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2020. By volume, Stefan sits between State Grid Electric Power Rerearch Institute Co. Ltd and Step Energy Services Ltd..
Stefan's three-year grant acceleration
Stefan Pfaff Werkzeug- UND Formenbau GMBH & Co KG shows 5 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.
