There are seven synthetic routes of substances in my invention patent that need to be protected, so how should I write the patent claim?

1. You need to determine whether your seven methods of synthesizing substances have the same necessary technical characteristics (that is, the same innovation points). If so, you can apply for a patent. If not, you may have to apply for several different patents or divide the case later.

2. The claim must be based on the specification, which must be fully disclosed, otherwise the patent right cannot be granted;

You need to protect the secret of this technology. The key is to grasp the degree of "full disclosure". Theoretically, this degree is to enable technicians in their fields to realize technical solutions after reading your patents; Therefore, specific problems have to be analyzed in detail. Your technical proposal is about the prospect of authorization, which can protect your core technical secrets with a wide range of protection. You have to think for yourself.

4. There is also an application called "confidential application", that is, the content of your application will not be made public, and the authorization announcement of confidential patent application only publishes the patent number, application date and authorization announcement date. For example, Yunnan Baiyao is a confidential application. See Chapter 5 of the Patent Examination Guide for details. However, you need to pay attention to your point of view. To put it bluntly, patent is the open exchange of monopoly. If you apply for confidentiality review, exploitation and use by others after your application date does not constitute infringement.

I hope it helps you.
