问:欧洲专利维持费的起始计算日期是不是其最早优先权日?
答:根据欧洲专利公约(EPC)第86条第1款规定如下:“Renewal fees for the European patent application shall be paid to the European Patent Office in accordance with the Implementing Regulations. These fees shall be due in respect of the third year and each subsequent year, calculated from the date of filing of the application. If a renewal fee is not paid in due time, the application shall be deemed to be withdrawn.”
