prominent positions within European mediation networks, including serving as the first president of the Slovenian Association of Mediators from 2006 to 2011. 1.3 Specific Procedural Issues The Ljubljana Local Division adheres to the pro - cedural framework established by the Unified Patent Court Agreement (UPCA) and its Rules of Procedure. As these procedures are stand - ardised across all UPC divisions, the Ljubljana Local Division follows the same general proce - dural rules as other divisions across participating EU member states. As of April 2025, no cases have been initiated before the Ljubljana Local Division. Consequent - ly, no division-specific procedural issues have been identified yet. Furthermore, the language of the proceedings before the Ljubljana Local Division can either be Slovenian (as the official language of the state hosting the UPC division) or English (as the additional language, designated by the UPC division).

As of April 2025 and mentioned in 1.3 Specif- ic Procedural Issues , no case has been initi - ated before the Ljubljana Local Division. This includes all types of actions, such as infringe - ment actions, revocation actions, actions for declaration of non-infringement, applications for preliminary injunctions, applications for pres - ervation or production of evidence, and merits hearings. Therefore, no statistics information is available as of April 2025. The current inactivity of the Ljubljana Local Division can be attributed to several factors, including litigants’ preference for other jurisdic - tions and the early stage of the UPC system in Slovenia. As awareness of the UPC’s frame - work increases and stakeholders become more acquainted with its procedures, it is expected 2. Statistical Information 2.1 Types of Actions
