The term of protection of trademarks and patents is different: the term of protection of patents is limited, 2 years for inventions, 1 years for new designs and designs, and cannot be renewed upon expiration. The trademark is protected for 1 years, but it can be renewed when it expires, so as long as it is renewed every 1 years, it can have the exclusive right to use the trademark indefinitely. 3. The contents of trademark and patent protection are different: patent protection shall not manufacture, use, promise to sell, sell or import products that are the same as or similar to the patent.
