Classification Codes

Once we have completed a free-text subject search, we may want to restrict our search to specific classes of inventions. Within the U.S. patent system similar subject matter is brought together in large groupings called classes. There are also international class codes.

Classification Codes are numbers that are assigned to patents by the patent issuing authority. U.S. class codes are searched with the prefix CL=; international class codes use the prefix IC=.

Dates

Dates can be an effective way to narrow a search. We can search on publication/patent year, publication/patent date, or application date and year.

The table below illustrates the different formats.

Field Format Example
Application Date s ad=YYYYMMDD
s ad=YYMMDD
s am=YYMM
s ay=YYYY
s ad=19980204
s ad=980204
s am=9210
s ay=1998
Publication/Patent Date s pd=YYMMDD s pd=990401
Publication/Patent Year s py=YYYY s py=1999

Note: You can also use a four-digit month: AM=YYYYMM.
