Would constitute patent infringement.
Because your improvement is just to modify the shortcomings and add functions. Generally speaking, modifying the shortcomings cannot change the basic principles and main structure of the product. The basic composition of the circuit diagram is included, so the main features of the product cannot be changed. As for adding functions, it also belongs to adding technical features of the product. However, you can only avoid infringement charges by reducing the essential technical features of your patented products. Therefore, if you plan to sell the improved electronic products to Taiwan, IMHO, the risk is too great. Besides, mainland China is the only country in the world that is the worst at enforcing patent laws. It promotes patent agency subsidies, but no country in the world has patent subsidies. They all rely on patent protection to mobilize people's enthusiasm for applying for patents. of. Taiwan's patent protection is very strict.
Electronic products are Taiwan’s strength. There are many copycat electronic products and computer hardware products, which are the softest technical fields in mainland China. Only Taiwan can keep up with the world’s advanced technology and is slightly behind us. The Chinese nation strives for success. Taiwan ranks fourth in the world in terms of the number of patent applications filed in the United States. You must not compete with Taiwanese manufacturers on electronic products.
