To prevent forfeiture of trademark rights from failing to apply for renewal, a trademark right holder is still entitled to file an application for renewal six months after the expiration of the term of trademark rights; however, the registration fee shall be doubled. In other words, if the government fee for filing a renewal application for a trademark or collective trademark is NT$4,000 per class and NT$4000 per application for a collective membership mark or certification mark, the fee for renewing a trademark or a collective trademark would be NT$8,000 per class, and NT$8,000 per application for a collective membership mark or certification mark, if the renewal application is filed six months after the expiration of the term of trademark rights.
