What is a PCT National Phase Patent Application in India?

A PCT application allows inventors to file a single international application to reserve their right to seek patent protection in multiple countries. However, to obtain actual patent protection in India, the applicant must enter the national phase in India within 31 months from the earliest priority date.

If this step is delayed, the right to seek patent protection in India may be lost.

Timeline and Deadline for PCT National Phase Entry

The deadline to file a PCT national phase patent application in India is 31 months from the priority date of the international application. Timely filing is critical. ZwapAll IP ensures all documentation and formalities are completed well before the deadline, avoiding last-minute errors or rejections.

Requirements for PCT National Phase Patent Filing in India

To enter the national phase, an applicant or their authorized Indian Patent Agent must submit the following documents to the Indian Patent Office:

1. PCT Patent Application Number
2. Power of Attorney (Form 26) authorizing ZwapAll’s Government of India–registered Patent Agents
3. English Translation of:
• Description
• Claims (both as originally filed and amended, if applicable)
• Abstract
• Any text matter in drawings
4. Official and Professional Fees, payable via Telegraphic Transfer

Upon request, additional documents may be required:

• Copy of the international application (if not received from the International Bureau)
• Verification of translation accuracy
• Instrument of assignment (if the applicant is not the inventor)
• Inventor details (name, address, nationality)
• Documents showing any change in applicant’s name
• Details of corresponding applications filed in other countries (for filing Form-3 within six months)
