Hello, none of the above conditions can apply for a patent. As long as it is a new technology, new process or new product, patent application must have three characteristics: novelty, creativity and practicality. It must be emphasized that new products that have been put on the market for sale, that is, they lose their novelty, can no longer apply for patents. Anyone who meets these characteristics can apply for a patent.
If you apply for a patent, I suggest you find a patent agency to help you apply for a patent. You can go to China Patent Network. Com, analyze the data of all patent agencies provided by this website, and find a company with the best qualification to help you apply, so that the success rate of patent application is relatively high.
