Trademarks can last forever if they are renewed on time. Keep in mind you will have to continue using your trademark to keep it in good standing.

For US national registrations, the first Section 8 Declaration of Use is due between the fifth and sixth anniversaries of registration. Combined Sections 8 and 9 maintenance and renewal filings are due between the ninth and tenth anniversaries, and every ten years thereafter. A six-month grace period is available with additional fees. Each retained good or service must meet the use requirement unless qualifying excusable nonuse applies. Madrid-based US registrations require Section 71 filings, while international renewal is handled separately through WIPO on the international registration’s renewal schedule.

In European Union, Germany, the United Kingdom, India and Australia, you have to renew your trademark every 10 years. The 10 year term counts from the application date.

In China, trademarks have to be renewed every 10 years. The renewal period is counted from the date of registration.

In Canada, a trademark has to be renewed every 10 years (the renewal period was changed from 15 to 10 years in June of 2019). The 10 year term counts from the registration date.
