What are the common patent attack strategies?

At present, there are eight common offensive strategies: 1 and basic patent: this is a patent strategy that accurately predicts the future development direction of technology and takes core technology or basic research as the basic direction. 2. Peripheral patent war: that is, the strategy of adopting many different patents with the same principle and surrounding other people's basic patents to strengthen confrontation with basic patentees. Or when one's basic patent is attacked, weave a patent net around the basic patent and take the method of layer-by-layer containment to confront it. 3. Patent transfer: that is, among the patents obtained in many technical fields, the strategy of actively transferring the patented technology that you do not implement to other enterprises. 4. Patent purchase: the strategy of buying all competitors' patents to monopolize the market. 5. Combination of patents and products: that is, the strategy of imposing one's own products on the other side and allowing others to use the patents of the enterprise to improve their position in the market competition. 6. Combination of patent and trademark: that is, the strategy of exchanging the right to use patent and trademark. 7. Patent application for capital, technology and products export: that is, the strategy of applying for patents in importing countries before capital, technology and products are exported to protect the exclusive rights of capital, technology and products. 8. Patent backflow: that is, the strategy of digesting, absorbing and innovating imported patents to form new patents and then transferring them to the original patent export enterprises.
