Do I use other people's patents for infringement?

It depends on the specific situation: first, if the product that has applied for a patent is developed and manufactured for the purpose of production and operation, it is regarded as infringement; Second, if it is for experiment, scientific research and personal use, it is not infringement. Article 11 of the Patent Law stipulates that after the patent right for invention and utility model is granted, no unit or individual may exploit its patent without the permission of the patentee, that is, it may not manufacture, use, promise to sell, sell or import its patented product for production and business purposes, or use its patented method and use, promise to sell, sell or import the product directly obtained according to the patented method. After the design patent is granted, no unit or individual may exploit the patent without the permission of the patentee, that is, it may not manufacture, promise to sell, sell or import its patented products for production and business purposes.
