I don't know anything about Innix, but I will let you in on a trick that helped me track down an obscure korean tech company a few years back. Most hardware will have an FCC number printed on it somewhere. I'm not sure if memory cards do, but it is true of most electronic products. You can search for the FCC number on http://www.fcc.gov/oet/fccid/ and you'll get lots of information about the company including contact addresses, etc.
I wasn't able to find anything useful about Innix in my searching either, even when trying Google Korea.
