How does the USPTO handle correspondence from multiple attorneys in a patent application?

The USPTO has specific guidelines for handling correspondence from multiple attorneys in a patent application:

  • If multiple attorneys are listed on the Power of Attorney form, the USPTO will direct all correspondence to the first listed attorney.
  • The first listed attorney is considered the ‘correspondence address’ for official communications.
  • As stated in MPEP 403.01(a): ‘If more than one attorney is of record, the Office will direct correspondence to the first listed attorney in the Power of Attorney.’
  • Other listed attorneys can still communicate with the USPTO, but official correspondence will be sent to the designated address.

This approach ensures clear communication channels and prevents confusion in multi-attorney cases.
