Excuse me, I entrusted a patent agency to apply for a patent before, but now I have written a more detailed article to apply for priority. Can I change agents?

Of course. But I need to remind you that if you have a cooperation period with the first patent agency, you must negotiate with the agency before changing it. When it comes to related patent information, you must be careful; As for your application priority. You can do detailed filing and patent application consultation in Zhuanzhihui.
