What are the requirements for the Luxembourg invention patent application documents?

OPI conducts only formality examination of invention patent applications. The applicant needs to file a search request within 18 months from the filing date, or submit a search report issued by any official search agency within 18 months from the priority date, and the judgment of novelty in the search report does not affect the Luxembourg patent granted.

OPI does not conduct substantive examination for utility models (short-term patents). If no search is carried out or search reports from other countries are provided, it will only be protected as a short-term patent.
