Additionally, patent classes, inventors, and applicants relevant to the field of the invention may be acknowledged and used in the search strings to refine the search strategy. Further, all the search results must be analyzed manually to shortlist the most relevant prior-arts. Therefore, only the abstract and the search results title should be read for the first level of screening.

After shortlisting the relevant prior-arts, their citations can be checked to ascertain more relevancy and results around the shortlisted ones.
