Patent infringement is equivalent and different.

Legal analysis: The difference between patent infringement and equivalence is as follows: 1. The same infringement refers to the infringement that the technical scheme of the product or method accused of infringement directly falls within the scope of the written description of the protected patent claim; 2. Equivalent infringement refers to the technical scheme of the product or method accused of infringement, although it does not directly belong to the literal description scope of the claim, but it is not essentially different from the technical scheme of the claim, and accordingly it is recognized as the infringement that actually belongs to the protection scope.

Legal basis: After the patent right for inventions and utility models is granted in Article 11 of the Patent Law of People's Republic of China (PRC), except as otherwise provided in this Law, no unit or individual may exploit the patent without the permission of the patentee, that is, they may not manufacture, use, promise to sell, sell or import their patented products for production and business purposes, or use their patented methods and use, promise to sell, sell or import products directly obtained according to the patented methods.

After the design patent is granted, no unit or individual may exploit its patent without the permission of the patentee, that is, it may not manufacture, promise to sell, sell or import its patented product for production and business purposes.
