The costs of obtaining and maintaining a patent depend on factors such as the number of independent claims, the length of specification, the convention priority rights claimed and objections raised during the examination by the NOIP.
Payment for the costs can be made in one or several times. For example, application fees including fees for filing, claiming priority right (if any), and publication can be paid on the filing date. Examination fees including fees for conducting patentability search and substantive examination can be paid when a request for substantive examination is filed. Granting fees including fees for grant, registration and publication of patent, and the first annuity are paid upon being invited by the NOIP in a notification of result of substantive examination.
The total costs include official fees and service charges. The service charges are subjected to 5% value added tax. Other disbursements such as telephone calls, faxes, postage, courier and copying will be charged on the basis of the actual expenses.
