The INPI patent database offers access to the following content (domains):
- FR: French patent applications or utility certificate applications (FR) published since 1902.
- EP: European patent applications (EP) published by the European Patent Office (EPO) since the start (1978).
- WO: international applications (WO) published by the World Intellectual Property Organization (WIPO) since the start (1978).
- SPC: applications for Supplementary Protection Certificates published by the INPI since 1993.
- Documents of limitation requests
Note that according to the domain and the period in question, the information available for an application (bibliographic data, patent family, status, original documents, file inspection) may differ.
The data are taken from INPI, EPO and WIPO publications.
The Patent database was built based on the following sources: DOCDB database and OPS service from the EPO and INPI data.
The status information (also called Information Register) concerns events in the life of the patent or SPC, from publication to lapsing or expiration. This information includes the representatives, the owners and licensees for France.
It is available for:
- the published or granted French (FR) patent or utility certificate applications, European patents (EP) granted and designating France.
- in force in France
- no longer in force from 1999 if filed since 1989
- the Supplementary Protection Certificate (SPC) applications filed from 1993 (in accordance with the EC Regulations) and published.
The Patent database offers access to the following documents in PDF format:
- Application specifications
- Specifications of patents or utility certificates granted (starting in 1989 for FR)
- Specifications of French translations of European patents starting in 1995 (EP T)
- File inspection for FR applications filed since 2001 and SPC since 1993
- Documents of limitation requests
2. Update and deadlines ▲
The Patent database is updated at 0900 CET every Friday, publication day of the Patent Official Gazette (Bulletin officiel de la propriété industrielle - BOPI) by the INPI.
Friday updates include the following new publications:
- FR or SPC published by the INPI in the BOPI that day
- EP published by the EPO on the preceding Wednesday
- WO published by the WIPO on the preceding Thursday
The latest FR, EP, WO and SPC publication numbers available on the Patent database are displayed on the homepage.
Note that a weekly update does not forcibly contain new SPC publications.
Certain information is subject to specific update periods:
- abstracts of new EP applications published in English or German are translated into French by the INPI and uploaded to the database on average 3 weeks after the initial publication. Therefore, for a recent EP application published in English or German the abstract that is not translated into French is available.
- a paid renewal fee appears between 2 and 3 weeks after receipt by the INPI. Partial payment of renewal fees is not indicated.
- file inspection is made available according to their type, 15 days after registration by the INPI.
3. Search ▲
You can limit your search by selecting only the domains of interest to you.
- selecting just the FR domain offers additional search criteria: by representative or department of applicant.
- a greyed-out criterion indicates that the query is not applicable to the domain selected:
e.g. if the SPC domain is the only one selected, the Classification and Inventor criteria no longer apply
The basic search uses the following criteria: title in French, abstract in French, product INN for an SPC, IPC classification, applicants, inventors, publication number, application number or publication date.
If you enter several terms, for example lentille? ophtalmique? Essilor 2013, the results found include necessary all these terms and you get for example, the applications filed by Essilor, containing the terms lentille(s) et ophtalmique(s) in the title or abstract and published in 2013.
The advanced search function proposes further search criteria in addition to the normal search: CPC classification, application date, grant date, priority date, entrie numbers in the French patent register;
By selecting only the FR domain, you can also search for : representative and department of applicant.
Certain criteria do not apply to certain domains: e.g. for SPC queries, the Classification and Inventor criteria are not applicable.
Available wild cards are: ?, *, #. They can be used in front of or behind a character string.
? = 0 or 1 character: often used to search for a term in the singular or plural: friteuse? searches based on friteuse or friteuses.
* = 0 to multiple characters: used to search for terms
- starting with: hertz* returns hertz(s) or hertzien(s) or hertzienne(s)
- ending with: *mab retrouve obinutuzumab or pertuzumab or siltuximab
# = 1 character: organi#ation.
Use quotation marks to search for an identical expression: for example, the search "champs opératoires à fenêtre" in the abstract returns all applications containing this exact expression in the abstract.
Available operators are: ET, OU, SAUF (and, or, not)
|Search in abstract:||returns applications where the abstract contains:|
|air OU atmosphère||the word air or the word atmosphère|
|fixation? ET ski?||the word fixation(s) and the word ski(s)|
|grippe SAUF aviaire||the word grippe but not the word aviaire|
If you combine operators, use parentheses. For example: (fibre? OU transmission?) ET optique?
In basic search mode, the default operator between search terms is ET (and): if you input several terms: lentille ? ophtalmique ? Essilor 2013, the results include all these terms and for exemple, you will get the applications filed by Essilor, contaning lentille(s) et ophtalmique(s) in the title or abstract and published in 2013.
In advanced mode, the default operators are:
- for check boxes: OR: e.g. in the title OR in the abstract
- for criteria: title: AND; abstract: AND; Number OR; Classifications: AND; Applicants: AND; Inventors: AND; Rights holder: AND; Department: OR; Representative: AND; French patent register entries: OR
So a search for semelle thermoformée both in the title and abstract is transposed as follows:
(Title OU Abstract = semelle) ET (Title OU Abstract = thermoformée)
The basic search mode enables searches in French on the title, abstract or International Nonproprietary Name (INN), subject of an SPC application.
In advanced mode, you can search using French keywords in the patent title (including the INN, subject of a SPC application), in the abstract or both at once. The default operator used between search terms is ET(and).
So a search for fibre optique both in the title and abstract is transposed as follows:
(Title OU Abstract = fibre) ET (Title OU Abstract = optique).
Use wild cards, especially ? to manage singular and plural words: fibre? optique?.
The wildcard * can be used in front of or behind a character string :
- hertz* returns hertz(s) or hertzien(s) or hertzienne(s)
- *mab returns obinutuzumab or pertuzumab or siltuximab
Use SAUF(not) to exclude certain words, for example: fibre? SAUF câble? or the operator OU to add synonyms to your search terms. If you combine operators, use parentheses. For example: (fibre? OU transmission?) ET optique?
To search for an identical expression, use quotation marks: "fibre optique" only document where this exact expression appears in the title or the abstract will be returned.
Dashes and slashes are not recognized by the system, please use spaces instead.
The best results are obtained by combining keywords with IPC or CPC classifications.
- FR applications published prior to 1978 have no abstract in French
- EP applications published less than 4 weeks ago in English or German do not systematically have an abstract in French.
The application No. is that assigned to a patent application when it is filed. It includes the year of filing.
The publication No. is that assigned to a patent application when it was first published.
The basic search mode enables you to search using the publication No or the application No
In advanced mode, you can search using the publication No., the application No. or both (if you do not know the kind of No. you are searching for). The default operator between two search terms is OU(or):
The number formats are as follows:
|Application number|| FRAANNNNN
EP98938690 = EP98938690.9
|Publication number|| FRNNNNNNN
| EP1 à NNNNNNN
EP999999 = EP0999999
The EP application No is searchable with (EP98938690.9) or without the control digit (EP98938690)
Patent applications are classified technically by Patent Offices using the International Patent Classification (IPC) system managed by the WIPO. FR, EP and WO applications are also classified according to the Cooperative Patent Classification (CPC) which is an extension of the IPC and is managed jointly by the European Patent Office (EPO) and the American Patent Office (USPTO).
Patents stored in the database are classified according to the latest versions of these classifications. SPC are not subject to IPC or CPC technical classifications.
The basic search mode enables you to search using the IPC symbol.
In advanced mode you can search using the IPC, CPC or both at once. The default operator between two search terms is ET(and)
The following input formats are possible:
Wild cards or boolean operators can be used to refine your search. So the search query: A61K31/0* returns all patent applications with classification symbols starting with A61K31/0 (/00, /01 ,03 etc.).
The applicant is the party applying for the patent or SPC.
Search using applicant name is available in both basic and advanced modes. The default operator between two search terms is ET(and).
The search is applied to the name itself: use the significant terms and avoid legal forms.
You can adapt your query using boolean operators or wild cards or search for an identical expression using speech marks: "Dupont de Nemours »
Pay attention to the use of acronyms and abbreviations: to search for all variants, use the wild card and alternative spellings – e.g. CNRS OU (Cent* ET Nat* ET Rech* ET Scien*) ou encore Univ* ET Paris ET (cinq OU 5 OU V)
This criterion is available in both basic and advanced search modes.
The search is done on the surname and/or forename of inventors. The default operator between two search terms is ET(and).
This search does not apply to SPCs.
The search function by department, overseas communities or territories is available in advanced mode if only the FR domain is selected.
The search is done on the number of the French department for French patent applications published since 2002.
You can search by applicant department No for the FR applications published since 2002.
The default operator between two search terms is OU(or).
Department number: 54 (Meurthe et Moselle)
987 (French Polynesia)
Whole region: 54 55 57 88 becomes 54 OU 55 OU 57 OU 88, (departments in the Lorraine region).
Important: if you want to count patents, e.g. the number of French patents applied for in 2010 by an applicant based in department 54, ensure you disable the display option:
"Group results by patent family" in the advanced search form.
The search by representative function is available in advanced mode only if only the FR domain is selected. Note that the representative information is available for French applications since 1989.
The default operator between search terms is AND but your search can be refined using Boolean operators or wild cards or you can search for an identical expression using speech marks.
The publication date corresponds to the date of publication of the patent application or SPC application
The filing date is the date on which the application was received
The grant date corresponds to the date of publication of grant
The priority date is the initial filing date used for an application claiming priority from an earlier application.
The publication date is available in basic and advanced modes, the other dates are only available in advanced mode.
You can search by year, month or day in the following formats:
YYYY : 2014
YYYYMM : 201402
YYYYMMDD : 20140214
In advanced mode, you can use numerical operators or search within a time range.
Note: grant date is searchable for the FR applications, EP applications designating France filed since 1989 and SPC since 1993.
The French patent register (RNB) is used to record actions affecting the existence, validity or exploitation of a patent or patent application, utility certificate or utility certificate application, SPC or SPC application.
This search is available in advanced mode.
You can search using entry No. with or without 0: 199083 is the same as 0199083. You can also use the wildcards to retrieve a range of entrie No. 19908? returns entries published with No. from 199080 to° 199089. The default operator is OU(or).
|abstract||Since 1978||Recent applications published in English or German are not available in French||Not applicable|
|representative||FR for applications filed since 1989||Not available||Not available||Not available|
|department||FR for applications filed since 1989||Not available||Not available||Not available|
This is the default search option in both basic and advanced modes. It can be disabled in the advanced search mode.
This option relies on the notion of simple patent family which groups patent applications filed worldwide for the same technical content. In other words, a simple patent family contains patent applications with the same priority or combination of priorities. Grouping the results by patent family only displays a single member of the family in the results list. The other members of the family can be viewed in the record.
For example: a WO application and an EP application concerning un système d’arrosage (sprinkler system) were filed claiming priority from an earlier French application. These three FR, WO and EP applications have the same priority and are present in the Patent database.
For a keyword search using the search term: arrosage (sprinkler):
- if the "Group results by patent family" option is enabled, only the FR application is displayed in the results list and the EP and WO applications can be identified in the FR record
- if the option is disabled, the 3 applications (FR, EP and WO) will be present in the results list.
In the results list for an advanced search, the summary of search criteria specifies whether the "Group results by patent family" option is active or not.
Reminder: this option is active by default in basic search mode.
Important: the "Group results by patent family" option does not provide a precise count on a search criterion as the results are grouped by family. For example, if you want to know the number of French patent applications filed in 2010 by a person residing in department 54, disable the Grouping option.
For more information on patent families
This option serves to select the number of results returned by page: 10 (by default), 30 or 50.
4. Results list ▲
If your search results contain over 500 responses, only the first 500 will be displayed. To limit the number of results, you can modify the search by adding a date criterion, for example.
Results are displayed in descending order of date of publication. This option is selected by default in the " Sort by " menu.
By default, the list is sorted in descending order of date of publication. You can change this option and sort in descending order of publication number.
The "Filter by." option is enabled when the "Group results by patent family" option is disabled in the advanced search form.
The following filter criteria are available: IPC, Applicant, Domain (FR, EP, WO or SPC). You can filter the display according to the ten most frequent terms found in all results.
If you activate a filter, the option is shown at the top of the list in "Related searches".
