When a utility model and an invention patent are applied at the same time, in the stage of utility model authorization and invention examination, if the utility model does not pay fees, will it affect the process of invention examination? I don't think so. Because the utility model and the invention patent are applied at the same time, the utility model must be authorized first, while the invention patent examination is stricter and the examination time is definitely longer. In this case, you will invalidate the authorized utility model patent without paying the fee. Although it will not affect the process of invention examination, your utility model patent has passed, which may not necessarily lead to the examination and approval of invention patent. If so, your patent will eventually become public technology, and your technology will not be protected. You can choose the paid protection of utility model patents that have been authorized before, and then choose the paid protection of invention patents after the invention patents are authorized.
