Frequently asked questions
What can Smart Search do, and how is it different from Keyword Expansion?
I entered a US application number for a patent search, but ended up with a different issue number from PAIR. Why?
Is there a way to use a query that screens out the "old" publication patent number with the same application number given it has been issued?
I used "quotation" to search for exact phrase, but why do some patents, without the phrase, are showing up?
Can I use figures of a design patent on PS directly to find similar-looking patents?
In a Classification Query, what's the difference between classification with "Hierarchy" and without?
What's Semantic Search? What can it do?
How Can I Print, Export, Download (Save or Add to Project) A Patent?
How to adjust the number of search results shown on a single page on PS?
How do I sort my search results on PS?
Why's there "no data" appearing on some patents' pages on Patent Search?
I want to highlight the synonyms of my queried keyword in the same color. How do I do this?
The keyword doesn't appear in the patents of the search results on PS
I want all words with the same root word to be highlighted on the patent page. Is this possible?
