January 2023: Errors in PCT numbering
WIPO has experienced a software error which caused the numbers for initial publications in the first three PCT publication batches of 2023 to be allocated following on from the numbers used in 2022. As a result, PCT numbers in the January 5, 12, and 19 publications run as follows:
| Gazette | Number of Initial Publications | Numbers Allocated |
|---|---|---|
| 01/2023 | 6807 | 2023/272317 to 2023/279123 |
| 02/2023 | 4536 | 2023/279124 to 2023/283659 |
| 03/2023 | 4684 | 2023/283660 to 2023/288343 |
According to WIPO, numbering will resume from WO 2023/000001 on January 26 and publications in December will skip the range used in January.
