In particular, the opposing party shall provide the following evidence:
(a) if the opposition is based on a trade mark which is not a Community trade mark, evidence of its filing or registration, by submitting:
(i) if the trade mark is not yet registered, a copy of the relevant filing certificate or an equivalent document emanating from the administration with which the trade mark application was filed; or
(ii) if the trade mark is registered, a copy of the relevant registration certificate and, as the case may be, of the latest renewal certificate, showing that the term of protection of the trade mark extends beyond the time limit referred to in paragraph 1 and any extension thereof, or equivalent documents emanating from the administration by which the trade mark was registered;
(b) if the opposition is based on a well-known mark within the meaning of Article 8(2)(c) of the Regulation, evidence showing that this mark is well-known in the relevant territory;
(c) if the opposition is based on a mark with reputation within the meaning of Article 8(5) of the Regulation, in addition to the evidence referred to in point (a) of this paragraph, evidence showing that the mark has a reputation, as well as evidence or arguments showing that use without due cause of the trade mark applied for would take unfair advantage of, or be detrimental to, the distinctive character or the repute of the earlier trade mark;
(d) if the opposition is based on an earlier right within the meaning of Article 8(4) of the Regulation, evidence of its acquisition, continued existence and scope of protection of that right;
(e) if the opposition is based on Article 8(3) of the Regulation, evidence of the opposing party's proprietorship and of the nature of his relationship with the agent or representative.
