Fall 2018 - CS/CZ: Change of number format

Post by EPO / Patent Data Services » Thu Nov 29, 2018 11:46 am

Please be informed of a change of number format affecting:
• publications with authority code = ‘CS’ and kind code = ‘A1’, ‘A2’, ‘A3’
• publications with authority code = ‘CZ’ and kind code = ‘A3’
• applications and priorities with authority code = ‘CZ’ and kind code = ‘A’ from 2000 onwards

Publication numbers before 2000 were converted from YYnnnnn to (nnnn)nYY – by moving year to the end of the number and suppressing embedded zeroes
CS A1, A2, A3 from CS 8100874A1 to CS 87481A1
CZ A3 from CZ 9900002A3 to CZ 299A3

Publication numbers from 2000 onwards were converted from CCYYnnnn to CCYY(nnn)n – by suppressing embedded zeroes
CZ A3 from CZ 20160007A3 to CZ 20167A3

Application and priority-numbers from 2000 onwards were converted from CCYYnnnn to CCYY(nnn)n – by suppressing embedded zeroes
CZ A from CZ 20000151A to CZ 2000151A

The correction had an impact on approximately
• 43.000 CS A1, A2, A3 publications
• 57.000 CZ A3 publications
• 26.800 CZ A applications with authority code ‘CZ’
• 7.500 applications with an authority-code other than ‘CZ’ – claiming applications with authority code ‘CZ’
