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.
Reinstatement of priority is accepted on grounds of "due care."
6 months before the filing date/priority date.
The novelty grace period is 12 months before the filing date/priority date.
- Licensing Fee: None.
- Annuity: Renewal fee is paid every 5 years (within 12 months before the validity period expires). The annual fee can be deferred up to 6 months after the due date, subject to a late fee of 50.00 EUR.
6 months before the filing date/priority date.
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.
