Reduction of the opposition fee 

The opposition fee is reduced if the notice of opposition including the written reasoned statement of grounds is filed in an admissible non-EPO language as well as in an EPO official language in translation (see T 290/90). If, during the opposition procedure only, an opponent files a document that has to be filed within a time limit in an admissible non-EPO language, he is not given a reduction in the fees.
