Does more volume mean deeper claims for Kjellberg-stiftung?

Each dot is one of Kjellberg-stiftung’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). Kjellberg-stiftung’s own 17.3 claims/patent is ABOVE the 7.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Kjellberg-stiftung's grants concentrate

Kjellberg-stiftung is a focused PatentsView assignee: 2 CPC subclasses with 84.6% of grants classified under H05H (Plasma Technique ; Production OF Accelerated Electrically-charged Particles OR OF NEUTRONS; Production OR Acceleration OF Neutral Molecular OR Atomic Beams). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2015. By volume, Kjellberg-stiftung sits between King Steel Machinery Co., Ltd. and Koofy Innovation Limited.

Kjellberg-stiftung's three-year grant acceleration

Kjellberg-stiftung shows 6 grants in 2022–2024 against only 4 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.
