Overview of Patent Renewal
Patent renewal is crucial for maintaining the validity of a Patent. The Patent owner must ensure that the Patent is renewed regularly to keep it in force. In India, the renewal fee must be paid to the Indian Patent Office before the expiration of each relevant year. For example, the renewal fee for the 6th year must be paid before the end of the 5th year from the Patent's registration date. The Indian Patent Office offers various options to facilitate the renewal and restoration of Patents.
If the renewal fee is not paid on time, the Patent expires. However, the Patent can be restored by filing a Patent Restoration request (Form 15) within 18 months from the expiration date. The restoration, though, is subject to the Controller's discretion.
Payment of Patent Renewal Fees in India
The renewal fee must be paid to the Indian Patent Office before the expiration of the relevant year. According to the Patent Act, the Patent owner can also pay renewal fees in advance for multiple years. To make the payment, the Patent holder needs to provide the Patent number, the date of the Patent, and the relevant year for which the fee is being paid.
For additional Patents, no separate renewal fee is required, and the payment schedule remains the same as for the main Patent. If an additional Patent becomes independent, it follows the same rules as a standard Patent.
If the renewal fee is not paid by the due date, there is an option to extend the payment period by up to 6 months, provided the applicable penalty is paid. Additionally, if the Patent is granted more than two years after the filing date, the outstanding renewal fee must be paid within 3 months of the Patent grant date, as recorded in the Patent Register.
In summary, the renewal fee must be paid before the start of each subsequent year, with a six-month extension option available upon payment of a penalty.
