The invalidity search is done to invalidate a patent in question by finding out potentially similar patent and non-patent literature. Businesses opt for this type of search to invalidate the grant of a patent, access the strength of a patent, fix appropriate royalty/licensing mechanisms, decide on mergers and acquisitions, and to avoid infringement issues. 

We perform the following steps to perform invalidation/ validation searches:

1. Identifying the claims of the patent that are in the scope of the purpose of the search. 
2. Identifying the prior art of the claims that are challenged. 
3. Identifying relevant keywords and classification for the questioned claims.
4. Planning the search strategy.
5. Identifying relevant prior art.
6. Analyzing results.
