My seventh strategy…

As we discussed about the use of Derwent database as one of the search strategy, there is an efficient way to do it. I would recommended to first perform a search on general database (Delphion) before moving on to Derwent.

This provides the searcher a feel of the results (what already exist in the domaiin) and the various keywords to use, which inturn helps in making the query more efficient and most important complete.

My sixth search strategy…

I guess alomost everybody here must have used delphion..

Used keyword based search ….

Browsed through 1000s of patent publications to find out the relevant results…

We all know Derwent but very few of us have tried it…

My personal experience, in case of invalidation search, always try atleast two queries on Derwent…

It will always be beneficial..
