Nice Classification NCL(13-2026) content is credited to the World Intellectual Property Organization (WIPO/OMPI). WIPO's current open-access policy generally licenses new online content under CC BY 4.0, subject to any specific exceptions and third-party rights.

IPI / Swissreg and examination records

The Swiss Federal Institute of Intellectual Property is the source of the WDL terminology, public Swissreg examples and examination-support extracts. The examination PDF contains IPI practice and references to selected TAF/TF decisions; it is not a complete court database. Official decisions and qualifying official collections fall within Article 5 of the Swiss Copyright Act. The IPI also publishes a general rights notice. This service does not claim ownership of source materials or grant a blanket redistribution license for them.

Corpus limitations

The snapshot includes 45 Nice headings, 41,539 WDL terms, 75,155 Swissreg goods/services rows covering 25,823 marks, 1,346 class examples and 549 examination entries. Only 83 examination entries have extracted TAF references; the parser reported 246 warnings. Swissreg representative metadata cannot be joined to every goods/services row. These are reference examples, not an exhaustive or current clearance search.

Source identifiers, dates and limitations accompany tool results. The original source snapshot and generated database are unchanged. Refer to official sources when a filing or legal conclusion depends on a result.
