Can an assignment be filed on paper with the USPTO?

An assignment can indeed be filed on paper with the USPTO, making it permissible to submit such documents via traditional mail. This option acknowledges that, while the USPTO encourages electronic filings due to efficiency and quicker processing times, there is still the provision for applicants who prefer or require a paper submission. This flexibility allows individuals or entities to manage trademark assignments in a manner that suits their circumstances, whether due to technical limitations or personal preference.

Filing an assignment on paper does not restrict it to any specific category of trademarks, such as international trademarks, nor does it require in-person submission. Since the option to file on paper exists, it provides an alternative method for those who may not have access to electronic filing systems or who may be more comfortable with conventional paperwork.
