New Numbering System

CGPDTM has launched a new unique numbering system for Patent Applications and Requests for Examination filed at the Patent Office w.e.f. 1st January, 2016. The numbering system has been standardized and streamlined with a view to attain uniformity in accessing and processing applications by all Patent offices in India (Delhi, Mumbai, Chennai and Kolkata).

  • Year of filling (YYYY)
  • Jurisdiction (J) – 1 for Delhi, 2 for Mumbai, 3 for Kolkata and 4 for Chennai
  • Type of application (T):
    • 1 for ordinary
    • 2 for ordinary- divisional
    • 3 for ordinary – Patent of Addition
    • 4 for Convention
    • 5 for Convention –Divisional
    • 6 for Convention – Patent of addition
    • 7 for PCT NP
    • 8 for PCT NP- Divisional
    • 9 for PCT NP – Patent of Addition
  • Application serial number (NNNNNN)

The new numbering system would have 12 character fixed length format for Request for Examination as well. The format would be:

RYYYYJNNNNNN or XYYYYJNNNNNN

 Where,

  • R denotes normal request u/r 24B(1)(i),
