TMEP § 819.02(j)
If the mark includes non-English wording, the application must include an English translation of that wording. 37 C.F.R. §2.22(a)(14). If the mark includes non-Latin characters, the application must include a transliteration of those characters. 37 C.F.R. §2.22(a)(15).
The insufficient information fee will be required if a translation and/or transliteration is omitted. 37 C.F.R. §2.22(b). If the initial application includes a translation and/or transliteration, no additional fee will be required if the translation/transliteration is later amended. However, the additional fee will be required if the translation or transliteration comprises inappropriate material, such as the notation "???." See id.
