20.6.4.1 Notes
No Inventors are entered for utility models, only the Assignee is available. When using DISPLAY and SELECT the PA
field is used in place of the IN field.
It may happen that in some cases the first name of an Inventor is erroneously entered in /INA. First names should,
therefore, be searched additionally in /INA; the surname in /IN and the first name in /INA must be linked by (S)
proximity.
20.6.5 EPFULL
There are special SEARCH fields for the address details of the inventor, of the patent assignee, of the agent, of the
opponent and the agent of the opponent:
/INA, /PAA , /AGA, /OPA, /OPAGA: Address
/IN.CNY, /PA.CNY, /AG.CNY, /OP.CNY: Address, Country
/IN.CTY, /PA.CTY, /AG.CTY, /OP.CTY: Address, City
/IN.STR, /PA.STR, /AG.STR, /OP.STR: Address, Street
/PAN, /AGN, /OPN, /OPAGN: Number
/IN.COM: Comment on the Inventors
/PA.DS: Designated States
20.6.6 RUSSIAPAT
The difficulty of searching Russian names is discussed above.
In RUSSIAPAT the Patent Assignee field is divided into PA.AP (Patent Assignee/Applicant) and PA.AS (Patent
Assignee/Proprietor). In most cases only of these is filled. In addition these fields exist: /AG (Agent) with the name of
the agent (only partly filled) and /CA (Corporate Address, always filled) with the address and the name of the agent.

20.7.1 Inventor
The /IN (or /AU) field is phrase indexed. Therefore, it can only be searched by phrase. There is no implied proximity:
=> S ANDERA JOSEPH F/IN
L45 4 ANDERA JOSEPH F/IN
20.7.2 Patent assignee
The /PA (or /CS) field can be searched by name, country, and the assignee number either as a phrase or single words
(mixed index with interpretation of the query). (S) is implied proximity. If the name is to be searched as a phrase it
must be included in quotation marks, "..." (cf. DWPI).
20.7.3 CA, CAPLUS
In Chemical Abstracts there is a thesaurus on the /CO field with the most frequent name entries for large companies,
which can be used like this:
