How Long Does A Trademark Last? – 877-728-7763 – The Patent Professor®

Design patents can last up to 14 years and utility patents can last up to 20 years. Fortunately, trademarks do not have a shelf life, once your trademark is approved it is valid forever! There is a caveat, however, that after the first 5 years and then after every 10 years, you do have to renew your trademark. This is done to show that your trademark is still useful and that your product is still in the market. In this clip, The Patent Professor® explains the duration of a trademark.
