Accordingly, a new format of numbering will be implemented with effect from 1st January, 2016.

The new numbering system for patent applications shall have 12 characters fixed length numeric standard Patent Application Format, applicable to all the Patent Offices in India and shall include identifiers of Year of filing, Jurisdiction, type of application and application number.

Revised Numbering system format as effect from 1st January 2016:

Patent Application Number: YYYYJTNNNNNN

  • "YYYY" denotes four digit fixed length Year of filing
  • "J" denotes fixed length single digit Jurisdiction* in numerals
  • "T" denotes fixed length single digit Type of Application** in numerals
  • "NNNNNN" denotes 6 digits fixed length common continuous running serial number applicable for all Patent Offices in India

* Jurisdiction

The "NNNNNN" series of applications shall be unique and sequentially incremented for all the four patent offices in the order of their filing.

Similarly, the numbering system of Request for Examination shall also be unified and standardized. A normal Request for Examination of patent can be filled as per rule 24(1)(i) of Patent Rules 2003 and an express patent examination request for PCT application can be filled as per rule 20(4)(ii) of Patent Rules 2003.

  • "R denotes Request for examination u/r 24B (1) (i)
  • "YYYY" denotes four digit fixed length "Year of filing"
  • "J" denotes Jurisdiction for Patent Application against which Request of Examination has been filed
  • "NNNNNN" denotes 6 digits fixed length common continuous running serial number* applicable for all Patent Offices in India
  • "X" denotes Request for examination u/r 20 (4) (ii)

  • "J" denotes jurisdiction of Patent Application against which Request has been filed 
  • "NNNNNN" denotes 6 digits fixed length common continuous running serial number* applicable for all Patent Offices in India

*Both the serial numbers u/r 24B (1) (i) and u/r 20 (4) (ii) shall be common

 

Date of Application shall accompany the Patent application number and Request for Examination application in the following format: YYYY/MM/DD

The streamlining of type of patent application will be very helpful in reducing the time required for examination of patents and prosecution of patent application in India.
