IKOFAX mode

As an experienced user, you can conduct searches constructed directly in the IKOFAX Messenger query language - the internal search language of DEPATIS. You can access all fields in the DOCIDX database.

A list of searchable fields is available in the section "Searchable Fields" of the Help pages.


Syntax for search expressions

Search Terms

In this search system, search terms are individual words, not phrases or parts of sentences.
For this reason, only the following types of search terms are allowed in search expressions:

These are words consisting of letters and digits but not containing word separators.
Word separators are

Not being a word separator, the @ character is allowed in terms.

These are terms which additionally contain the following truncation characters as wildcards for one or several characters:
? for any number of characters or no characters
! for precisely one character
# for one character or no characters


Truncated terms are allowed in the following fields:


You may also use spaces if the term is enclosed in single quotes.
Example: 'A01B 3/16'/IC

Before performing the search, the system will transform the character string enclosed in single quotes into a standardised form without spaces. Field-specific standardisation rules are applied for this purpose.


Operators

Use the following operators in search expressions.
A list of examples on how to use operators is given below.

In DEPATISnet, some data fields - for example, title, abstract, publication number or publication date - are combined to field groups. Field groups are, for example, "Applicant/Owner" and "Inventor" (the only fields where names occur), all IPC symbols (IC) or Full text data (BI). The field operator allows to restrict the use of a search term to one field F or several fields F1, F2,...,Fn.

Examples:
< Schulte/PA > finds all publications of the applicant/owner "Schulte".
< Schulte/PA,IN > searches for "Schulte" in the field "Applicant/Owner" and in the field "Inventor" (IN).

< Motor/TI > finds all publications containing the word "Motor" in the title.
< Motor/TI,CL > finds all publications containing "Motor" in the title or in the claims.
< Motor/TI,DE > searches in the field "Title" and in the field "Description".
< Motor/TI,CL,AB > searches in the fields "Title", "Claims", "Abstract".
< Motor/BI > searches in the full text: title, claims, abstract, description.

Where, prior to executing the search in the system, search terms are converted into a standardised form not containing spaces or special characters by field-specific standardisation rules, only fields following the same standardisation rule may be specified in the field operator. Likewise, it is not allowed to specify fields belonging to different field groups.

Finds all documents containing both search terms.

Finds all documents containing at least one of the two search terms.

Finds all documents not containing the search term.

Finds all documents containing search term 1 directly followed by search term 2.

Finds all documents containing search term 1, not directly followed by search term 2.

Finds all documents where search term 2 occurs within a specified number (n) of words after search term 1.

Finds all documents where search term 2 directly follows search term 1 and vice versa, that means, in contrast to (W), regardless of their order.

Finds all documents in which the search terms occur within n words of each other, in either order.

Finds all documents containing both terms in the same paragraph.

Finds all documents containing both search terms in the same part of a data field (sub-component).
The L operator will cause the system to put your entered data in the desired relation to each other during the search.
Example:
Anna Meier of Lemgo and Bernd Huber of Olpe are joint applicants of the invention "XY".
An application for the invention "YZ" was jointly filed by Anna Huber of Kehl and Bernd Meier of Lahr.
If you search in the "Applicant" field for "Anna Huber"
< (Anna (L) Huber)/PA >
the search will return only the (correct) result regarding the invention "YZ".
The search will also return this result if you enter < (Kehl(L)Huber)/PA > or < (Anna(L)Kehl)/PA >.
It is true that the invention "XY" also contains the components "Anna" and "Huber" in the data field "Applicant", but these components are not contained in the same part (since here the first name "Anna" is allocated to the family name "Meier" ).

Further examples of sub-components are linked index classes (consisting of several IPC symbols) or priority data (consisting of date, country and number).

You can use comparison operators to restrict your search to a specific data pool - for example, to patents published after 1 January 2010.

Comparison operators always relate to one field F (specified by a field operator) and are used for numerical comparisons (for example, for dates which are mapped values). They can also be applied to all other fields. For fields with a standardisation rule, the lexicographical order of the standardised representation applies (for example, for DocIDs or IPC symbols). Although comparison operators may be used for full text fields, they are hardly suitable since it is not likely that they return the result you expect, because all words of the respective field are included in the comparison.

Locates all documents containing in field F at least one value which is less than the search term. The other comparison operators have corresponding effects.
Example: /pub < 10.01.2010 , the publication date (pub) is before 10 January 2010

Locates all documents containing in field F at least one value greater than the search term. The other comparison operators have corresponding effects.
Example: 10.01.2010 < /pub

Locates all documents containing in field F at least one value between the upper limit and the lower limit. Where, for the lower and upper limits, the same operators are used in conjunction with "=", for example ">=" the value may also be equal to the upper or lower limit, respectively.
Examples: 01.01.2010<=/pub<=30.01.2010
(Publication date from 1 January 2010 to 30 January 2010), F01C9/00<=/ic<=F01C11/00 (IPC search in the range from F01C9/00 to F01C11/00)
(Please enclose the IPC symbol in single quotes in the search for IPC areas, as in this example: 'F01C9/00'<=/ic<='F01C11/00?.)

If necessary, you can change the order of precedence by applying rounded brackets, for example (< search term 1 > OR < search term 2 >) AND < search term 3 > or (< search term 1 > OR < search term 2 >)/F.
