New version of ePCT available

WIPO has released a new version of ePCT, its online service for secure filing and management of international patent applications. 

Version 4.18 incorporates several refinements to improve the user experience for both applicants and patent Offices, including: 

  • automatic language checks on certain uploaded documents, helping identify issues before submission; 
  • a new option to view sequence listings in a more user-friendly format; and 
  • workflow refinements for Receiving Offices, International Searching Authorities and International Preliminary Examining Authorities. 

For full details, refer to the ePCT User Guide.
