Advanced search options

Add search operators to your search terms for a more targeted search or to search for terms with similar spellings. You can also restrict your search to individual fields. All search operators can be used in combination with each other.


Please note that some of the following examples of search results are from the trade mark database. The databases work in the same way, however.



Restrict your search with AND or NOT

If you search for several terms in the patent database, these will be connected by OR by default. Each result will contain at least one of these search terms.

james bond

James Bond 007, JAMES DEAN, Petro Bond.


The search operator AND

If you combine search terms by using AND (or and), you will find all IP rights that contain these terms. You can also place a plus sign (+) before compulsory search terms.


Search Results

pro AND vita
Or: pro and vita
Or: +pro +vita

PROVITA Gesundheitsversicherung AG, VITA pro, ProVita Medical


The search operator NOT

If you want to exclude search results containing specific terms, please combine the terms to be excluded by using NOT (or not) or by placing a minus sign in front of them.

Or: +emmi -AG

Emmi-Dental, Emmi Ultrasonic GmbH, Emmi-Nail, EMMI PUR


Search for exact word sequences with " "

If you want to search for exact word/character sequences, place them in double quotation marks (e.g. "for you"). You will only obtain search results in which the word sequences exactly match what you entered.


Search Results

"for life"

FOR LIFE, Wisdom for Life, RACE FOR LIFE

"quo vadis"

Quo vadis Drossapharm, Quo Vadis Reisen


Search for terms with variable characters with * and ?

You can use placeholders to search for terms with variable characters. For example, a word with various endings (table, tables, tablecloth) or words with different spellings (colour, color). You can position the placeholders at the start, the end, or the middle of a word or in several positions in a word.


The options are:

  • ? for exactly one character
  • * for any number of characters (including zero)

Sette Torri, Settore di formazione esame tessile, SETLINE, Never settle for less, Setelle


Search for similar terms with ~

Place a tilde symbol (~) at the end of a word to perform a fuzzy search, in other words, to search for similar terms. You will find character sequences that vary from your term by up to two operations (insertion, deletion or substitution of a letter).
Example: a search for spot~ will find spit (o is replaced by i – varies by one operation) and pet (s deleted and o is replaced by e – varies by two operations).  
Use ~1 to allow terms to only differ by one operation (insertion, deletion or substitution of a letter) – and thus to obtain fewer results.  
Keyboard shortcuts for the tilde symbol: for Windows: Alt Gr and ^, for Mac OS: Alt and N, for Linux: Alt Gr and +, each followed by a space.

Search within ranges with [TO]

You can use [TO] to search within a range, for example, within a number series.


Search Results

patentno:[CH713500 TO CH713600]

All patents with a patent number between CH713500 and CH713600


Search in specific fields

By default, various fields are searched, including all titles, patent and application numbers and the addresses of all owners, inventors and representatives. For example, if you search for motor, you will find all IP rights that contain motor in the title, as well as all IP rights belonging to the owner Ford Motor Company.
For a more targeted search, you can restrict it to single fields by using the advanced search. Alternatively, you can enter the names of the fields in the search box or refine the search via the results list.


The following fields are available:


Field Description

Title of the patent or patent application – e.g. Motor

Patent number

e.g. CH718012 or EP4006922

Application number

e.g. "CH000021/2022" (application numbers contain a forward slash (/) and therefore need to be put in double quotation marks when searching)


Person or company, e.g. "Peter Meyer" or Migros. The search function looks for the search term in all the owner addresses.


Person or company that represents the patent owner vis-à-vis the IPI – e.g. Müller.


Person – e.g. "Peter Meyer". The search function looks for the search term in all the inventor addresses.


International Patent Classification – e.g. "H01B 5/08" (Note: there must be a space in the middle)


Cooperative Patent Classification – e.g. "C01G 33/00"
(Note: there must be a space in the middle)

PCT application number

Application number of the international application – e.g. "PCT US1997 011708" will find the international application with the application number PCT/US1997/011708 (Note: the forward slashes (/) need to be replaced by spaces)

PCT publication number

Publication number of the international application – e.g. "WO1997 045178" will find the international application with the application number WO1997/045178 (Note: the forward slash (/) needs to be replaced by spaces)


Search a field via the results list

In the results list, you will see exactly where your search term has been found (only in the list view). By selecting one of these fields, you can restrict the search to the corresponding field.


For example, if you search for Novartis and click on the field Representative: Novartis in the search result, you will only be shown IP rights that contain Novartis in the representative’s address.



Search a field via the search box

You can also input the fields you want to search directly in the search box. To do so, add the field name as a prefix before the search term, e.g. patentno:CH694783, owner:"Peter Meyer" or title:motor.

The field search can also be combined with search operators such as placeholders or AND or NOT connectors.
