This paper describes details of the NTT-NII system in NTCIR10 PatentMT task. The system is an extension of the NTTUT system in NTCIR-9 by: a new English dependency parser (for EJ task), a syntactic rule-based pre-ordering (for JE task), a syntax-based post-ordering (for JE task). Our system ranked 1st in EJ subtask both in automatic and subjective evaluation, and was the best SMT system in JE subtask.
