3. Search

Expert mode

The Expert mode may be the preferred search mode for experienced searchers, familiar with patent and utility model searches. This mode also allows to create complex search queries. In contrast to the Beginner's mode a large search query box is provided. Enter your search terms and the respective operators in this query box; the prescribed syntax must be followed exactly.

Choose from the drop-down menu the entry of the data field in which you want to search. Click on the chosen data field to transmit the corresponding field code to the search query box above. You can also directly enter the field code in the search query box.

Operators and wildcards can be transmitted in the same way.

Search examples are shown below.

Boolean operators
AND  logical AND 
OR  logical OR 
NOT  logical NOT 

Comparison Operators
greater than 
less than 
equal to 
>=  greater than or equal to 
<=  less than or equal to 

proximity operators
(W)  Finds documents containing the search terms in the specified order with no words between them.  
(NOTW)  Finds documents containing the search terms close to each other in the specified order, but not immediately next to each other.
Please note the search examples. 
(#W)  # defines the maximum number of words between the search terms. The order of the search terms corresponds to the order typed.  
(A)  Finds documents containing search terms in any order with no words between them.  
(#A)  # defines the number of words between the search terms. The order of the search terms is not relevant; # may be zero.  
(P)  Finds documents containing the search terms within the same paragraph.  
(L)  Finds documents containing the terms within the same subsection (segment) of a field. 
(D)  The search terms linked with this operator may consist of one word or of two consecutive words; this can be performed in one search query.
Please note the search examples! 

Truncation/ wildcards
no characters to any number of characters 
precisely one character 
zero or one character 

After a left truncation or setting of a placeholder at the left edge an input of further truncations/placeholders is not allowed
Allowed entries:

Invalid entries:

At the bottom of the search form one button is provided:

  Submit your request by clicking the "Start Search" button. The hits will be displayed in form of a result list.

Search in the abstract for terms "Jodlösung" or "Borlösung"
(exactly three characters preceding "...lösung")

(no or up to 3 characters preceding "...heizung")  
TI = ###heizung 
Search in the claims for terms "Fahrzeug" or "Kraftfahrzeug" or "Nutzfahrzeug"
(no or infinitely many characters preceding "...fahrzeug")  
CL = ?fahrzeug 
Search in the full text for terms "Programmabschnitt" or "Programmabschnitte" and "Administration"/"administrativ"/"administra..."  BI= (programmabschnitt# AND administra?) 
Search for the bibliographic IPC < F17D 5/00 >  ICB=F17D5/00
ICB='F17D 5/00'
ICB=F17D0005000000 (standardised) 
Search for the search file IPC < F17D 5/00 M >  ICP=F17D5/00M
ICP='F17D 5/00 M'
ICP=F17D000500000M (standardised) 
Search for the bibliographic IPC < F04D 13 > [with all subgroups]   ICB=F04D13/?
ICB='F04D 13/?'
ICB=F04D0013? (standardised) 

Search examples for the proximity operator (NOTW)

Expert mode:
Bi = (mechanische (NOTW) Regler))
The first query will only find documents where the first search term is included; the second search term may but does not need to be included.
However, if the second search term is included in the text, it must not directly follow the first search term.

Bi= (Regler und (mechanische (NOTW) Regler))
The second query will only find documents where both search terms are included.
However, the second search term must not directly follow the first search term.

Search examples for the proximity operator (D)

Expert mode: Bi= (multi(D)media)

Searches in the date fields "Publication date", "Application date", "Priority date":

For information on all admissible entry formats for date values please refer to Help chapters "Searchable fields" -> "Publication date "

Searches in the text fields "Title", "Abstract", "Description", "Claims", "Full text data":

The following should be noted for search queries with word separators (see list below):
Convert word separators into the proximity operator "W".
If a search request contains search terms with a word separator these will be treated like two separate terms following in a direct sequence. This has the advantage of returning also publications containing a search term with a word separator that differs from the word separator you used in your search request. For example the term 'DVB-T' (with a hyphen) will also return 'DVB T' (with a space).

Example in the "Title" field:
Search for documents with a title containing the term "DVB-T"
Search: << TI = ( DVB(W)T ) >>

You want to search for the word "Personalcomputer" in the title or full text. To find all occurrences of the term "Personalcomputer" as well as its spelling variations "Personal-Computer" (with a hyphen) or "Personal Computer" (in two words) at one time you should enter the below search request in the Expert mode.

Type in the following search query on the Expert search form:

Full text data: BI= (personalcomputer OR (personal(W)computer))

Titel: TI = (personalcomputer OR (personal(W)computer))

Word separators are

The @ character is not a word separator.

Searches in the fields "Applicant/Owner", "Inventor":

In case of several applicants or inventors, these data fields contain two or more data components each consisting of the respective first name + family name + town + country code (for companies: company name + town + country code). To separate them, enter a semicolon between the names of the applicants or inventors. Use the (L) operator for a search in these fields. This operator will prompt the system to put your entries in the desired relationship to each other during the search.

Anna Meier of Lemgo and Bernd Huber of Olpe are joint applicants of the invention "XY".

To search for one of the applicants, here "Anna Meier", in the field "Applicant/Owner? enter: PA = ( Anna(L)Meier )
Due to the (L) operator the search will return only the (correct) result regarding the invention "XY". The search will also return this result if you enter PA = ( Meier(L)Lemgo ) or if you enter PA = ( Anna(L)Lemgo ) .

If you want to search for both applicants, you must enter the following query:
PA=((Anna(L)Meier) and (Bernd(L)Huber))
A search for PA=(Meier(L)Huber) or PA=(Anna(L)Huber) will not return any result at all or an incorrect result, since the (L) operator only searches in a subsection (segment) of the data field, not over the entire field.
It is true that the invention "XY" also contains the components "Anna" and "Huber" in the data field "Applicant/Owner", but not in the same subsection (segment).

Configure result list

In the "Configure result lists" section you can customise your result list. Tick the check boxes provided which correspond to the columns to be displayed on the result list. You can choose the following columns: "Publication number", "Title", "Inventor", "Applicant/Owner", "Publication date", "Application date", "Search file IPC", "IPC main class" and "Abstract".

The drop-down menu for sorting the result list allows you to sort the result list by different criteria. Select the desired data field and choose (ascending/descending) order.

The drop-down menu labelled "Results/page" allows you to choose the number of results (10, 25, 50, 100, 250 or 1000) to be displayed per page. The default value is 50.
