Indian Patent Applications in CA/CAplus

On January 8, 2007, Indian patent applications from the Office of the Controller General of Patents, Designs, and Trade Marks have been added to CA/CAplus.  Coverage is retroactive to December 4, 2004.

Patent kind codes in CA/CAplus have been modified as follows:

• Kind code A patent applications
• Kind code A1 granted patent specifications

Patent applications and PCT applications may be filed at one of four provincial offices in India (IN).  However, the assigned patent publication numbers are identical among the offices, e.g., the first Indian patent publication number issued from each office in 2007 is IN 2007-1.

To resolve the problem of identical Indian patent publication numbers, CA/CAplus includes patent publication numbers modified with one of eight codes to identify application type and filing office.  The codes include:

• MU national application filed in Mumbai
• MN PCT application filed in Mumbai
• KO national application filed in Kolkata
• KN PCT application filed in Kolkata
• DE national application filed in Delhi
• DN PCT application filed in Delhi
• CH national application filed in Chennai
• CN PCT application filed in Chennai

In addition, Indian patent publication numbers in CA/CAplus include the sequential number padded with zeros (to five characters) and the patent kind code.  For example, the number assigned to the first patent publication from a patent application filed in 2007 at the office in Mumbai is:

IN 2007MU00001 A
