The Indian Patent Office (IPO) has introduced e-filing services for patents way back in 2007, with the objective to carry out all communication and financial transactions online. The portal enabled users to file for new patents online. Stakeholders are successfully using this service. In an attempt to make the process more transparent and user friendly, the IPO has further developed the patent e-filing service. In addition to e-filing of patent applications, subsequent filings have also been integrated. The registered applicants, also have personal folders in the IPO's secure environment.

Trademark e-filing


In India, to file for trademark online, the user needs to buy a class 3 digital signature certificate. Users can buy digital signature certificates online in India, from any certifying authority or a registeration authority. To sign the trademark e-filing application, the user needs to select particular application '532' and then choose 'sign document'. On the computer screen, a window appears on which all the installed class 3 digital signatures will be listed. The user can choose the appropriate certificate and sign the document electronically. After this, the user will receive a notification that the document has been signed.

Class 3 certificates ensure the highest level of security when documents are exchanged electronically via the internet. The digital signature verifies the identity of the person signing the documents. 

After submission of the digital certificate, the user can proceed to make the payment. Once the user selects the 'Make payment' option, the system will display the amount the user has to pay. The user can make the payment through a credit card or through net banking. The portal allows users to carry out net banking with the State Bank of India or Axis Bank.

Once the payment is made successfully, the user will be redirected to the trademark e-filing portal. Here the user can view the receipt for payment. The receipt can also be printed at a later time.
