Company Act Article 18

A corporate name shall be in Chinese Character. No company may use a corporate name which is identical with that of another company or limited partnership. Where the corporate names of two companies or a company and limited partnership contain any marks or identifying words respectively that may distinguish the different categories of business of the two companies, such corporate names shall not be considered identical with each other.A company may conduct any business that is not prohibited or restricted by the laws and regulations, except for those requiring special approvals which shall be explicitly described in the Articles of Incorporation of the company.Any category of business to be conducted by a company shall, when making the registration thereof, be identified with the Category Code applicable to the said business category as assigned in the Table of Categories of Businesses by the central competent authority. For a company which has already been registered, and the category of business conducted by it is registered with descriptive words, then, such descriptive words shall be replaced with the applicable Category Code as assigned in the foregoing Table, while applying for alteration of the entries of existing company registration record.A company shall not use a name which tends to mislead the public to associate it with the name of a government agency or a public welfare organization, or has an implication of offending against public order or good customs.Before proceeding to the company incorporation registration procedure, a company shall first apply for approval and reservation, for a specific period of time, of its corporate name and the scope of its business. Rules for examination and approval of such application shall be prescribed by the central competent authority.
