Workbook Title - FIZ Karlsruhe

Example: Search with the IPC code B60R 21/01 in the IPC field and limit to „Invention“ for new
IPC8 codes of 2006 or later:
=> S B60R0021-01/IPC
L1 14668 B60R0021-01/IPC
=> S B60R021-01/IPC(S)INVENTION/IPC.KW AND PY>=2006
14668 B60R021-01/IPC
(B60R0021-01/IPC)
46282035 INVENTION/IPC.KW
2836261 PY>=2006
L2 1922 L9 AND PY>=2006
A search in the IPC field retrieves the broadest answer set. By using the IPC.KW field limitation
to specific attributes (see table 1) is possible. IPC code and corresponding IPC attribute have to be
linked with the (S) proximity operator.
IPC codes can be entered with 7 or 8 digits before the hyphen (e.g., G02C0005-00/IPC or
G02C005-00/IPC) - reformatting is done automatically in STN.
