What are the necessary technical features? How to write the technical features? Technical features are an important process that needs to be described in the process of patent writing, so what are the necessary technical features of a patent? Before we know the necessary technology of a patent, we should know what the technical characteristics are. The so-called technical features refer to the technical means/solutions adopted to solve technical problems and realize the task of invention. Even if the characteristics are concentrated in the patented technology that constitutes one or more patented technologies, these are important guarantees for measuring a patent. How to write the technical features? The necessary technical features are the necessary technical means or schemes that constitute an invention or utility model. The sum of the two is enough to constitute the technical scheme of the invention or utility model, which distinguishes it from other schemes described in the background; On the other hand, non-essential technical features: the features that are dispensable in the technical scheme to solve the technical problems of invention and creation are called essential technical features. Technical problems can be solved without any unnecessary technical features. First of all, the patentee can list all the necessary technical features of the invention you apply for. Then, from all the listed necessary technical features, two types of necessary technical features are screened out: a, necessary technical features suitable for the existing technology, and b, necessary technical features different from the existing technology. Independent requirements for writing = subject name+class A necessary technical features+features: (features:)+class B necessary technical features. To sum up, we can understand that the essential characteristics of patent run through the core of the whole patent, and without the essential technology of patent, the patent cannot be implemented. Therefore, generally speaking, a patent with essential characteristics of multiple patents, if it is a patent with multiple patented technologies, can suggest the patentee to apply for multiple patented technologies through multiple protections, so it is not only an application for a patent for invention, but also an application for a patent for utility model.
