Do you need to write specific implementation when applying for an invention patent? Do you have to write the best implementation case when applying for a US patent?

If your invention is simple enough, as long as you write the technical scheme, the technicians in this field can realize your invention. I don't need to write the specific implementation. The specific implementation is not a hard requirement. This review guide is mandatory. Paragraph 2 of page 138 of the examination guide 20 10 clearly stipulates that "in the case that the technical scheme of the invention or utility model is relatively simple, if the part of the specification involving the technical scheme has clearly and completely explained the subject matter required to be protected by the patent application for the invention or utility model, there is no need to repeat the explanation in the part involving the specific embodiment". In other words, as long as you fully disclose your invention, it doesn't matter whether you write it or not. For example, if your ideas are exactly the same as your specific embodiment, you don't need to write specific embodiment. But if your idea has a superior summary, you should still give the realization. I don't know the American patent law, and I don't know whether to write it or not.
