I haven't been informed of the application of the new patent for more than two months, and the practice office has been keeping me waiting, which is depressing.

Give it to the firm, and you will get the acceptance notice soon. It's a little abnormal that you haven't got it for a month. You can bring the application number. If there is an application number, it proves that the patent has been submitted. If not, it may not be submitted or there are other reasons.
