E-Lead EL-460 might violates GPL

[魏藥/Medical-Wei]

Hello,
     I'd like to ask for the process of issuing a GPL violation,
because I found a product which might violated GPL or LGPL.
     I found that E-Lead [1] EL-460 [2] (a net-top) preinstalled
GNU/Linux (which is based on Ubuntu) has some modified packages which
is to cooperate with its proprietary program called Noahpad. Noahpad
is used to display the status of the special touchpad-keyboard. E-Lead
modified SCIM [3], which it is LGPL licensed, in order to show
different soft-keyboards for different input methods on the screen,
but I cannot get the source code neither of SCIM nor of Noahpad.
     It is possible that the program also violates GPL because of the
inheritance of Linux kernel and some part of GPL-ed programs.
     Months ago, I've mailed them for the source code of SCIM and
Noahpad, but they have no reply at all; maybe they didn't receive the
mail at all.
     Should I contact them in other methods? or what's the next step I
have to take?
