Don't ask, the answer might be no. :) The D-STAR logo does not seem to have (R) or (C) emblems which should be there if the logo is internationally protected by copyrights or is registered trademark.
IF it would be protected, there should be already quite good knowledge of such, as for a official logo property of someone has usually also graphical guidelines regarding the positioning, surroundings and limitations of the usage. I've seen the D-STAR logo attached to several other logos and backgroups, which are usually very no-no by the guidelines. Erik OH2LAK
