According to the now cancelled article 16(5), when a trademark registration was assigned, any identical or similar trademarks (for the same or similar goods or services) were also required to be transferred to the same assignee. In practice, when an application to record the trademark assignment was filed, the Turkish Patent Institute (TPI) would allow a two-month period in which to assign any remaining identical or similar trademarks. If the parties failed to comply with this requirement, the TPI would reject the assignment recordal request.
