"ubi.com" trademark does not mean anything bad to "ubi.me",
neither does "ubisoft" which is their main brand
"ubi" trademarks (i can see 4 live) mean you cant use it any connection with
1) circuit breakers,
b) children's furniture including diaper changing tables,
c) chemical reagents for immunodiagnostic tests for scientific and research
..you are very limited indeed
there are some companies with "ubi" in their names or acronyms - see ubi.info, ubi.de, ubi.ca or just search for "ubi".. theubi.com, myubi.tv, Union Bank of India, UBI Banca.. and Ubisoft (ubi.com) of course
one of them could be interested in buying the name with a trending social touch (.me), worth trying, nothing to lose..
good luck
