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 forseat 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.
