In some countries, digital signature certificates (DSCs) are required for online filing of trademark and patent applications. For example, in India, DSCs are mandatory for filing trademark and patent applications online through the government’s e-filing portal.
DSCs are used to authenticate the identity of the person or entity filing the application and to ensure the integrity of the electronic data being submitted. By using a DSC, the applicant can be sure that their application has not been tampered with or altered in any way during transmission.
