Often in PatSnap, you'll find a need to save your queries for another time, perhaps to continue work on them, or to use as a dynamic result set.
It's really easy to save a search, just look at the top of your search result list, and you'll see the age-old floppy disk icon. Once you click that, you'll get an option to name your search. Give it an appropriate name, and click "Save".
You can then find your saved search area in the tools menu which can be found by hovering over your initial in the top right-hand corner of the screen.
