Abstract:In order to give full play to the function of the product, the buyer or the third party manufacturers often take repairing, renovation and remanufacturing to the product, and becomes a role of "producer". Repairing on the certain level to the patent product is in conformity with "exhaustion of rights principle" of patent, not the formation of new manufacturing to the patent products. To promote the development of remanufacturing industry, we need take into account the interests of rights holders and the public, adhere to the principle of preventing the abuse of the patent right, get a reasonable distinction between normal repairing and illegal remanufacturing of the patent product, and make infringement analysis considering market factors, the characteristics of patent product, the difficulty of repair technology and other aspects. Finally, we put forward some reasonable and effective licensing strategy based on the infringement analysis.
