Mystery Canon case: can anyone help?

The IPKat wonders if any readers can help him. Information has just been posted on the Curia website concerning Case C-181/09 Canon Kabushiki Kaisha v IPN Bulgaria OOD, a reference for a preliminary ruling from the Sofiyski gradski sad (Bulgaria) lodged on 19 May 2009. This is an intellectual property case, so the IPKat is already deeply fascinated by it. However, today's notice reads:
"By decision of 17 September 2009, the Court of Justice (Fifth Chamber) declared the reference for a preliminary ruling to be manifestly inadmissible".
The Court's Order is only in French and Bulgarian. can anyone tell the IPKat and his readers what this is all about? Merpel also has a question: is there any significance in the reference being "manifestly inadmissible" rather than just the usual sort of inadmissible?
