What is patent improvement? Patent improvement refers to adding new features or functions, which constitutes infringement. Because judging patent infringement is a universally applicable principle, or the principle of all factors. If your improvement is based on someone else's patent, that is to say, some features and functions are added to someone else's patent, then the improved product still contains all the features of the previous patent except the added features, so it conforms to the principle of total factors.

In other words, they are all modified on the basis of others' achievements, but only need to apply for patents. This change must meet the requirements of patent authorization, that is, at least it must be novel, creative and practical. In short, the prior patent is A+B+C, and your use of A+B+C or A+B+C+X constitutes infringement. If your improvement is to reduce or replace some features or functions, it does not constitute infringement. Of course, the substitution here should exclude equivalent infringement. Therefore, whether the improved product infringes on the existing patent depends on the comparison between the final product and the basic patent, that is, whether it conforms to the universal coverage principle of patent infringement judgment. The content of the claims shall prevail. It is necessary to avoid adopting the principle of perimeter restriction, that is, the protection scope of patent right is exactly the same as that recorded in the written claim, and the claim only defines a general invention core, and the protection scope can be extended to the extent that technical experts think it belongs to the protection scope of the claim after reading the specification and drawings.
