Does more volume mean deeper claims for Topray?
Each dot is one of Topray’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). Topray’s own 10.6 claims/patent is ABOVE the 6.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Topray's grants concentrate
Topray Mems Inc. is a focused PatentsView assignee: 12 CPC subclasses with 56.3% of grants classified under H02K (Dynamo-electric Machines). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2016. By volume, Topray sits between Tokai Carbon Co., Ltd. and TP-Link Systems Inc..
Topray's three-year grant acceleration
Topray Mems Inc. shows 5 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.
