Validity search

For those who doubt the competitor's protection and want to check on what basis a patent was granted.

Are you uncertain whether your competitor really has the appropriate protection for their invention? Our experts can help you to search relevant prior art from far and wide, old and new, to help you find data that might challenge the validity of a patent.

What documents are required?

A validity search can be carried out for documents published in one of the Nordic languages (Swedish, Finnish, Danish or Norwegian) or in English, German or French. If you would like a validity search for a document published in another language, please contact our customer services for further information. Exceptions to this service are patent documents granted by PRV or patent documents that PRV has, in some respect, already searched for novelty.

The result

We present the results of the validity search in a report to you.

Our searches

PRV's patent engineers go through patent information and technical literature from around the world to help you find evidence that can question the validity. A validity search focuses on patent documentation filed before the priority date and Non-Patent Literature (NPL) published before the priority date of the document in question. Exceptions to this service are patent documents granted by PRV or patent documents that PRV has, in some respect, already searched for novelty.

The benefit of the service

You get clarity on how strong a patent is and if it has been granted on correct basis.

Complement with a written opinion

How well do the validity search references compare to the described invention? Use our experienced patent examiners whom with a problem-solution approach complement the validity search with a written opinion of the criterias of the patentability.

Additional service: Monitoring services

Please bear in mind that a result from a search reflects the situation of today. However, the patent documentation increases with 10 000’s of newly published patent documents every week, a fact which of course could have an effect on your search result. If you should be in need of continuous information – talk to us and we will prepare a monitoring profile.
