Thanks for those links!
For those who don't want to take the time to open them up, according to those links and
this one at the same site, Zhangwei, Mo and Yue, Jing (some people have said these two are married?) are the only ones with current ownership of the JETBeam trademark (first using it in 2006), while Sysmax's claim on that trademark has expired as of 11/27/2011. The Niteye trademark belongs also to Zhangwei, Mo. All the trademarks I found by Zhangwei, Mo and Yue, Jing have the same person (with the same address) listed as the contact person, a certain Anita Yu, which suggests that Mo and Jing are at least in some way connected.
On another note, a quick whois domain lookup for a few websites:
Nitecore.com Whois
Jetbeam.com Whois
Niteye.com Whois
Niteyelight.com Whois
The current Nitecore and Jetbeam sites are registered to someone in GuangZhou, both to the same yahoo email address. Niteye seems to have two sites with the same design with slight variations in the products featured, Niteyelight.com registered to someone in Shenzhen and Niteye.com to someone in Iowa.
