Search within the title, abstract, claims, or full patent document : You can
restrict your search to a specific field using field names.
Use TI= to search in the title, AB= for the
abstract, CL= for the claims, or TAC= for
all three. For example, TI=(safety belt) .
Search by Cooperative Patent Classifications (CPCs) : These are commonly used to
represent ideas in place of keywords, and can also be entered in a search term box. If
you're searching for seat belts , you could also search for
B60R22/00 to retrieve documents that mention safety belts or body
harnesses. CPC=B60R22 will match documents with exactly this CPC,
CPC=B60R22/low matches documents with this CPC or a child
classification of this CPC.
Keywords and boolean syntax (USPTO or EPO format) :
seat belt searches these two words, or their plurals and close
synonyms. "seat belt" searches this exact phrase, in order.
-seat -belt searches for documents not containing either word.
For searches using boolean logic , the default operator is
AND with left associativity. Note: this means
safety OR seat belt is searched as (safety OR seat)
AND belt . Each word automatically includes plurals and close synonyms. Adjacent
words that are implicitly ANDed together, such as (safety belt) ,
are treated as a phrase when generating synonyms.
Chemistry searches match terms (trade names, IUPAC names, etc.
extracted from the entire document, and processed from .MOL files.)
Substructure (use SSS= ) and similarity (use
~ ) searches are limited to one per search at the top-level
AND condition. Exact searches can be used multiple times throughout
the search query.
Searching by SMILES or InChi key requires no special syntax. To search by SMARTS, use
SMARTS= .
To search for multiple molecules, select "Batch" in the "Type" menu. Enter multiple
molecules separated by whitespace or by comma.
Search specific patents by importing a CSV or list of patent publication or application numbers.
