Yes, a patent title report can be updated after its initial preparation. While the MPEP Section 320 doesn’t explicitly state this, it’s implied by the fact that title reports are prepared at various stages of the patent process. Updates may occur:

• When new assignments are recorded
• If there are changes in inventorship
• When errors or omissions in previous reports are discovered
• At key stages of the patent process, such as before issuance

The Certificates of Correction Branch, responsible for preparing title reports, would likely generate updated reports to reflect any changes in ownership or other relevant information throughout the patent’s lifecycle.
