Stacking Queries
Queries can be stacked (or combined) in PatBase at any time via the command line. Queries are referred to by their assigned number, and Boolean operators AND, OR & NOT can be used to combine them.
In February of 2008, the system introduced the capability to combine a range of search queries using the terms “AND=” and “OR=”, with a colon operator to specify the range. For example, AND=1:4 will combine search strings 1, 2, 3, and 4 using AND operators between the searches, so that only results common to all four search sets will be found. Similarly, OR=1:4 will combine searches 1, 2, 3, and 4 so that the end result is additive, representing all unique hits from any of the four search strategies.
Editor's Note:The introduction of the AND= and OR= search terms will probably be a welcome time-saving device to many professional patent searchers, since a common search strategy is to search for one aspect of an invention at a time, and then to combine queries to narrow the search set.
