The mounting procedure of specifying the range of a character string and clicking on that character string is a proprietary technique of onClick, and can be clearly distinguished from other methods. Therefore, the providing of a similar user interface constitutes violation of the Prevention of Unfair Competition Act. Range specification refers to making a specified range appear to be visually distinct from other portions by highlighting a character string, underlining, changing character color, displaying in bold characters, surrounding with handles and rubber bands and so forth.
