What are the benefits of a request for copies of patent application documents?

There are no mandatory requirements, and I have not heard of any adverse effects.

Unless you have the following:

1. Copy of prior application documents (priority certification document);

2. Copy of patent certificate; (with** *Same patentee)

3. Replacement of patent certificate;

4. Copy of patent register; (such as checking the other party’s patent status)

etc. Special needs.
