At the USPTO, Patent Center is the next-generation system that incorporates all application submission types and file management functionality currently available in EFS-Web and Private PAIR, both of which will be retired on November 8. Additionally, Patent Center provides a more intuitive user interface for an enhanced experience by allowing you to:
• Upload multiple files at once using the drag-and-drop feature
• Upload the specification, claims, abstract, and drawings in a single DOCX document without the need to manually separate sections
