Patent searches

If the inventions which are described in the patent publications have never resulted in a granted patent, or if the patent has since expired, it may be safe to use these inventions. However, if a given patent remain valid, your continuous use will place you at risk of patent infringement and further filing of patent application will make no sense. In such respect, it is critical for you to know this at the start of your product development. This may result your proper actions. You may, for example, try to obtain a licence for this patent or change the direction of your product development to avoid further problems from this patent.


Other reasons for patent searches:


  • to find knock-out prior art that will prevent a patent, or at the very least make any patent that is obtained extremely narrow.
  • to assess whether a product developed by you is eligible for patent protection.
  • to get an idea of the technical field you are embarking on
  • to monitor the rights of competitors
  • to prepare for a possible opposition against the patent.


KENFOX has access to a large number of databases and registers, so that our patent lawyers can carry out a thorough search for clients. For in-depth or specialist searches, our patent attorneys work together with a number of specialist search offices. We evaluate the technical and legal implications of the results of these searches.
