Tell you the truth, the domains may have the risk of trademark issue, but if you can sell the domains to nike instead of have dispute with them ,you will got success!
The TRADEMARK ISSUE will cost nike inc at lest 5000$ on one domain ,if you sell the domains at the price below 3000$ ,I think ,nike would buy the domains .
Further more, nike used many domain names in china ,just like nikebasketball.com.cn nikefootball.com.cn niketranting.com.cn nikefive.com.cn and so on.
Thanks for confirming, when I see trademark issue, I would never take any chance at all.
Buying the trademark names, and then selling them to the trademark company is definately "NOT A GOOD IDEA". What if you they do not want the names, people just create more and more names using the "nike" in it, it doesnt mean they have to buy them all, instead it creates more trouble. lol.
You would be lucky if nike pays "50" for all of them, please no offense.
Thanks for your time, and good luck to you selling these to Nike.
