If the subcontractor infringes the patent right of others, what measures can the general contractor take as a co-defendant to resolve the litigation risk?

Without the permission of the patentee, no unit or individual may exploit its patent, that is, it may not manufacture, use, promise to sell, sell or import its patented products for production and business purposes, nor may it use its 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.

Therefore, as a general contractor, it depends on whether there are the above behaviors and whether there are other wrong behaviors.
