Subject search

A subject search provides you with an overview of the state of the art. It can help you:

  • avoid expensive duplicate developments
  • find solutions to technical problems
  • stay up-to-date with the latest developments in technology
  • obtain the needed basis for drafting a patent application.
Price: According to actual time spent carrying out the search plus database fees. We would be happy to provide you with an individual offer.
Delivery time: According to agreement - usually 5 working days


  • The Subject Search is also known as State-of-the-Art or Prior-Art Search.
  • The Validity Search delivers documents which could challenge the novelty or inventive step of an invention – for instance, for opposition proceedings or nullity actions.
  • While a Subject Search gives initial indications of whether a product or process could be infringing on a patent, it is not suitable for a definite determination of patent infringement. More in-depth analysis for this can be determined with an Freedom to Operate Search.
