What this shows Vacuumschmelze's Innovation Score is 59.0/100 (top 4% 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 Vacuumschmelze?

Each dot is one of Vacuumschmelze’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). Vacuumschmelze’s own 18.1 claims/patent is ABOVE the 14.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Vacuumschmelze's grants concentrate

Vacuumschmelze GmbH & Co. KG is a focused PatentsView assignee: 38 CPC subclasses with 67.5% of grants classified under H01F (MAGNETS; INDUCTANCES; TRANSFORMERS; Selection OF Materials FOR Their Magnetic Properties). Peak complete grant year is 2024 (12 grants) versus a trough of 3 in 2016. By volume, Vacuumschmelze sits between Tigo Energy, Inc. and Aida Engineering, Ltd..

Vacuumschmelze's three-year grant acceleration

Vacuumschmelze GmbH & Co. KG shows 30 grants in 2022–2024 against only 18 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.
