What happens if an assignee’s ownership changes during patent prosecution?

If an assignee’s ownership changes during patent prosecution, it’s crucial to update the USPTO records. As per MPEP 325:

“A new statement under 37 CFR 3.73(c) is required to be filed when ownership changes to another assignee.”

This means that:

• The new assignee must file a new 37 CFR 3.73(c) statement.
• The new statement must establish the new assignee’s ownership.
• Until the new statement is filed, the previous assignee remains the party of record.

It’s important to keep ownership records up-to-date to ensure that the correct party has the right to take action in the application.
