Patent office refine search results option
From the document results page on Scopus (once you have conducted a search), you will have the option to click on “View XXXX patent results”. This will open a new screen that will show the patent results based on the search string.
The patent search results will have a side bar on the left side on the screen to refine the search results.
From the refine results facets on the left, there is now an option to refine the search results on Patent Offices.
