How to deal with the infringement of invention patent?

Legal analysis: 1. Bring a lawsuit to the people's court (provided that the patent right is excellent, the evidence of infringement is complete, the infringement situation is serious or the infringement loss is serious); 2. Submit the case to the patent administration organ for administrative mediation (the obligee has mastered the preliminary evidence, and the infringement scale is not large or the loss is not serious); 3. Send a warning letter to the infringer (the obligee has mastered the preliminary evidence, and the infringement scale is not large or the loss is not serious).

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.
