Legal basis: According to Article 11 of the Patent Law, 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.
In addition, compared with for-profit organizations, non-profit organizations such as government agencies, institutions and public welfare organizations, which are mainly engaged in public management, social services and public welfare activities, may have more room to interpret their specific behaviors as "non-production and business purposes". However, if the patent application involved obviously participates in market activities and damages the market interests of the patentee, it is easy to determine that its behavior constitutes "production and operation for the purpose".
So in public welfare activities, you can't use other people's patents without permission.
