Examiner Searches Prior Art After Reading Specification and Claims
Note:
The examiner conducts a prior art search after thoroughly understanding the invention from the specification and claims.

The invention should be thoroughly understood before a search is undertaken. However, informal cases, or those which can only be imperfectly understood when they come up for action in their regular turn are also given a search, in order to avoid piecemeal prosecution.
