If the opposed party fails to submit an objection reply within the prescribed time limit, the Trademark Office will make a ruling ex officio. United States: After a trademark is reviewed and passed, there is also a 30-day opposition announcement period, but this period can be extended upon request. The objection procedure is very complicated and is known as a "small lawsuit". It is usually divided into 4 stages: The stage is the stage where the respondent submits the objection and defense, which lasts for 40 days. The second stage is the questioning stage of both parties, which lasts for 180 days. The third stage is the cross-examination stage of both parties, which lasts for 75 days. The fourth stage is the judge’s trial and ruling stage. Opposition cases in the United States are reviewed by a specialized review body, the United States Appellate Trial Board. It is worth noting that once the objection procedure begins, if either party fails to take corresponding actions within the time limit specified by law without any valid reasons, the U.S. Appellate Trial Committee will regard the party as automatically giving up the application or objection.
