AssessmentPatBase Express
Primary System StrengthsQuick and easy to use interface for beginners; access to all commercial PatBase data, including non-Latin text; faceted "Optimise search" window can allow quick refining of results.
Weaknesses and AnnoyancesCannot save search queries beyond one session; aggregated family data can cause some false hits.
Overall AssessmentThe tool provides functionality that is easy for beginners to learn, and coverage is large for a system with such a simple interface. However, the tool purposely lacks functionality needed by advanced and commercial searchers.
Company StrengthPatBase (and the related PatBase Express) is the only search tool offered by partners Minesoft and RWS. Since its introduction in 2003, the tool has continued to add new data and features. The addition of full text Asian data in 2008 and a visual explorer option in 2011 shows that the company is forward-thinking.
