The domain name that housed the website is currently up for bids in an expired domain name auction here. At time of publication, the current high bid is $1,035 with the auction ending on August 31, 2016 at 12:04 PDT.
Interestingly, although the domain name was “seized” October 26, 2010 based on the Wikipedia article, at that time, the domain name was renewed only until 7/27/2011. Between that time and February 21, 2011 the renewal was extended until 7/27/2013. Then the domain name was renewed once again for 3 years in 2013. During this time, David Berner & Lime Wire LLC were listed as the registrant, admin and technical contacts in whois records.
July 27, 2016 the domain name reached its expire date and has not been renewed this time around, so it has followed the registrar expired time frame and is now up for public auction.
There appears to be at least one (1) active trademark for LimeWire which had a 6 year courtesy reminder sent in 2015 but nothing has been posted to the TM since that time.
The domain clearly has a storied past to it, potential TM issue but bidding is active already with 9 different bidders and the auction only about 2 days old out of 10. You can view the auction here if you wish to watch or bid.
