Under what condition can you revive a trademark registration after it has expired or been canceled?

Reviving a trademark registration after it has expired or been canceled typically hinges on the presence of extraordinary circumstances that hindered the trademark owner's ability to respond in a timely manner, such as natural disasters, health crises, or other unforeseen events. This provision recognizes that there may be genuine reasons that justify the delay in taking necessary legal actions, allowing for rehabilitation of the registration under special circumstances.

In contrast, other options presented do not align with the requirements for revival. The mere submission of a fee does not provide a valid basis for revival, as the issue often relates to the inability to respond rather than the capability to pay. Similarly, submitting an amendment or having a new owner does not inherently justify bringing back a canceled registration without addressing the underlying reason for the lapse. The focus of the revival process is specifically on the extraordinary situation that led to the failure to maintain the registration.
