How does the USPTO handle correspondence for applications with multiple applicants?

The USPTO has specific rules for handling correspondence in applications with multiple applicants:

• For applications filed on or after September 16, 2012, the USPTO will direct correspondence to the first named applicant, unless a practitioner is appointed.
• For applications filed before September 16, 2012, correspondence is sent to the first named inventor, unless a practitioner is of record.

As stated in MPEP 403: ‘Where more than one attorney or agent is of record, the Office will direct correspondence to the first named attorney or agent of record, unless otherwise requested.’ This ensures clear communication channels for multi-applicant applications.
