Does more volume mean deeper claims for Leotek?
Each dot is one of Leotek’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). Leotek’s own 16.8 claims/patent is ABOVE the 14.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Leotek's grants concentrate
Leotek Corporation is a focused PatentsView assignee: 10 CPC subclasses with 37.5% of grants classified under H05B (Electric HEATING; Electric Light Sources NOT Otherwise Provided FOR; Circuit Arrangements FOR Electric Light Sources, IN General). Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2023. By volume, Leotek sits between LDA Technologies Ltd. and Lexvu Opto Microelectronics Technology (SHANGHAI) Ltd.
Leotek's three-year grant acceleration
Leotek Corporation shows 3 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.
