Article 44

1.   In opposition proceedings pursuant to Article 43, where at the filing date or date of priority of the later trade mark, the five-year period within which the earlier trade mark must have been put to genuine use as provided for in Article 16 had expired, at the request of the applicant, the proprietor of the earlier trade mark who has given notice of opposition shall furnish proof that the earlier trade mark has been put to genuine use as provided for in Article 16 during the five-year period preceding the filing date or date of priority of the later trade mark, or that proper reasons for non-use existed. In the absence of proof to this effect, the opposition shall be rejected.

2.   If the earlier trade mark has been used in relation to only part of the goods or services for which it is registered, it shall, for the purpose of the examination of the opposition as provided for in paragraph 1, be deemed to be registered in respect of that part of the goods or services only.

3.   Paragraphs 1 and 2 of this Article shall also apply where the earlier trade mark is an EU trade mark. In such a case, the genuine use of the EU trade mark shall be determined in accordance with Article 15 of Regulation (EC) No 207/2009.
