Does more volume mean deeper claims for Grover?

Each dot is one of Grover’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). Grover’s own 20.4 claims/patent is ABOVE the 11.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Grover's grants concentrate

Grover Musical Products, Inc. is a focused PatentsView assignee: 7 CPC subclasses with 100% of grants classified under G10D (Stringed Musical INSTRUMENTS; Wind Musical INSTRUMENTS; Accordions OR CONCERTINAS; Percussion Musical INSTRUMENTS; Aeolian HARPS; Singing-flame Musical INSTRUMENTS; Musical Instruments NOT Otherwise P).

Grover's three-year grant acceleration

Grover Musical Products, Inc. shows 2 grants in 2022–2024 against only 0 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.
