Whether the patent is transferred or not does not affect the priority. The so-called priority means that in the process of patent examination, in order to avoid the novelty and creativity of the patent being affected by certain languages, administrative procedures or other problems, it can be advocated that the filing date of a parent case should be taken as the examination benchmark date. This is called priority.
If it is a patent application in the process of examination, even if the patentee is changed, it has nothing to do with priority, so it will not affect it.
If the patent is to be transferred after examination, it has nothing to do with priority, so it does not affect it.
Therefore, patent transfer has nothing to do with priority.
