How to determine if a company name is the same as another?

In determining whether a company name is "the same as" another, certain words and their abbreviations will be disregarded. These words include the definite article where it is the first word of a name and the words "company", "and company", "company limited", "and company limited", "limited", "unlimited", "public limited company", the characters "公司", "有限公司", "無限公司" and "公眾有限公司" where they appear at the end of the name. The type or cases of letters, spaces between letters, accent marks, and punctuation marks, will be disregarded.

The following expressions "and" and "&", "Hongkong", "Hong Kong", and "HK", "Far East" and "FE" are respectively to be taken as the same.

In addition, a Chinese character is to be regarded as the same as another Chinese character if the Registrar is satisfied, having regard to the usage of the 2 characters in Hong Kong, that the 2 characters can reasonably be used interchangeably.
