Applicants for national or international IP protection are required to determine whether their creation is new or owned/claimed by someone else. To determine this, huge amounts of information must be searched. International classifications facilitate such searches by organizing information concerning inventions, trademarks and industrial designs into indexed, manageable structures for easy retrieval.
