Does more volume mean deeper claims for Hoya?
Each dot is one of Hoya’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). Hoya’s own 14.1 claims/patent is ABOVE the 13.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Hoya's grants concentrate
Hoya Glass Disk Vietnam Ltd. is a focused PatentsView assignee: 2 CPC subclasses with 85.7% of grants classified under G11B (Information Storage Based ON Relative Movement Between Record Carrier AND Transducer). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2019. By volume, Hoya sits between Houston Medical Robotics, Inc. and HTI Technology and Industries, Inc..
Hoya's three-year grant acceleration
Hoya Glass Disk Vietnam Ltd. shows 2 grants in 2022–2024 against only 2 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.
