TOKYO, Nov 16 (Reuters) - Hong Kong-based Oasis Management could go to court to seek a higher price for trading house Itochu's acquisition of a subsidiary through a so-called appraisal process, the founder of the activist fund said Thursday.

Oasis emerged as a major shareholder with a 6.42% stake in Itochu Techno-Solutions (CTC) after Itochu completed a tender offer that raised the parent's stake from 61.24% to about 86%. Itochu plans to take CTC private in December.

The appraisal process is designed to protect investors who oppose a buyout by allowing them to ask a judge to determine fair value of a stock. (Reporting by Makiko Yamazaki; Editing by David Dolan)
