Systematic searches for technical IP rights

Classifications allow the performance of language-independent, systematic searches.
More than 100 patent offices use the International Patent Classification (IPC) to achieve an internationally uniform classification of patent office publications. The IPC serves as a search tool for the retrieval of patent documents in order to establish novelty and evaluate the inventive step or non-obviousness including the assessment of technical advancements and possible exploitation or utility of technical disclosures in patent applications.
The International Patent Classification (IPC) serves as

  • an instrument for the orderly categorisation of patent documents in order to facilitate access to the technological and legal information contained therein
  • a basis for selective dissemination of information to all users of patent information
  • a basis for determining the state of the art for a patent
  • a basis for the preparation of industrial property statistics which in turn permit the assessment of technological development in various areas
