Does more volume mean deeper claims for Memory-tech?

Each dot is one of Memory-tech’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). Memory-tech’s own 3.1 claims/patent is at or below the 9.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Memory-tech's grants concentrate

Memory-tech Holdings Inc. is a focused PatentsView assignee: 1 CPC subclasses with 100% of grants classified under G11B (Information Storage Based ON Relative Movement Between Record Carrier AND Transducer). Peak complete grant year is 2017 (6 grants) versus a trough of 1 in 2015. By volume, Memory-tech sits between MATCH.COM, L.L.C. and Mitsubishi Heavy Industries Mechatronics Systems.

Memory-tech's three-year grant acceleration

Memory-tech Holdings Inc. shows 1 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.
