Primary System StrengthsUnique family based data structure; non-Latin language text content for JP, CN, KR, RU, TH, TW, and WO documents; non-Latin text search options; machine-translated English abstracts; versatile command line; excellent interface; heavy linking to free external data sources.
Weaknesses and AnnoyancesPossible although unlikely to lose current search history by accident (unchecking a box prior to log-in); aggregated family data can cause some false hits (same-publication field qualifiers may help with this problem) and long record display length.
Overall AssessmentThis unique tool takes advantage of many free on-line data sources such as links to legal status registers. The use of aggregated families promotes more efficient searching, and the user interface enables in-depth scrutiny of patent full text and drawings.
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.
