Excuse me, how many comparative documents will the examiner read after searching for an invention patent?

According to the communication with examiners, the retrieved documents are generally reduced to dozens or hundreds by restrictions, and then browsed, and some obviously irrelevant ones are eliminated for further research. It usually takes half a day to search. Of course, sometimes the examiner will work overtime. For foreign language documents that are difficult to search or have many documents, the search time may reach three days. I hope my answer can help you.
