Excuse me. I have made many improvements based on a patented product. The functional structure is more perfect, but some parts are the same, about 30%.

There are conditions for causing infringement. If the technical features of your product after improvement include all the necessary technical features of the product, it will cause infringement.

I don’t know how you calculated the 30% identical rate. If some of the same technical features happen to contain the necessary technical features of the patent, it will cause infringement. In addition, the products in the patent specification Not all content is protected, only the content recorded in the claims is protected.

If you don’t understand, you can ask questions
