A legal battle may yet jeopardise Ubisoft's recently announced September European release for Rocksmith.
Kris Roberts, who holds a trademark on Rocksmith as the name of his band, told Eurogamer that the trademark dispute remained unresolved.
"No agreement/deal has been reached and no meaningful dialogue engaged," he said, adding that Ubisoft's release plans rely on their winning the dispute with no complications.
"With the OHIM proceedings over the disputed trademark set to last for at least another two to three months, it's a bit presumptive to say the least, as to the outcome of that process and decision," he said.
Roberts claims to have brought the matter up with Ubisoft before lodging a trademark dispute, but couldn't reach a resolution with the publisher through other channels. Although he had to force a dispute or risk losing his trademark, Roberts has come under fire for delaying the European release, and he's keen to see the back of the whole debacle, no matter which way the courts settle.
"Either way I shall look upon it as a present, especially as it should stop the malicious and threatening abuse from dim witted potential Ubisoft customers," he said, adding that he is "genuinely pleased" a release is on the way for those who have been waiting for the musical training aid game.
Ubisoft had no new comment on the matter, stating only that is is looking forward to being the game to Europe and confirming its involvement in a trademark dispute.
Rocksmith is already available in the US, on playStation 3 and Xbox 360.
