You can also view your results by images by selecting in the View just above the result list: Image for images only; Simple +image for information such as IPC, application and inventor names and publication date, title and application number and All +image to see also the abstract on top of all the information in the Simple + image.

You can send your questions to or use our Forum available in the Help menu under Feedback & contact

It will allow you to download up to 10,000 results, save your preferred settings and queries; as well as to use the chemical structure search. Creating a WIPO account is free of charge.


For the most up-to-date information on what data is included in PATENTSCOPE. A patent application, its successive publications, and the potential patent count as 1 document in PATENTSCOPE.

All published PCT applications as well as patent collections from participating national and regional offices are available in PATENTSCOPE. The up-to-date information is available in PATENTSCOPE.

Yes, a large number of documents are available in full-text format, including the IP5’s front file and backfile.

The bibliographic data and documents of PCT applications are updated daily. The publication of new applications takes place weekly on publication day, i.e., Thursday, unless WIPO is closed for a public holiday (in which case the data are published on Friday). National and regional patent collections are updated on an ad hoc basis.

No, bulk download is prohibited. The usage of automatic robot is all prohibited. PCT raw data products are available for sale.


For detailed instructions on how to use the PATENTSCOPE database, please refer to the PATENTSCOPE User’s Guide PDF, PATENTSCOPE User’s Guide, the online tutorials, the free of charge webinars. You can indicate in your WIPO account that you would like to be notified about upcoming webinars.

As a first step, using the advanced search option (found in the drop-down menu “search”), you can insert and combine the most relevant keywords (separated by a space) in the search fields for the technology you are interested in, e.g. hybrid, car , etc. (you can also use inverted commas “” to find an exact phrase). A complementary means of searching existing patents is to use the International Patent Classification (IPC), according to which patents have are divided into specific technical groups. All you need to do is enter a keyword to try the IPC search.

Whilst our online searches are helpful, we would always advise you to seek further information from your national patent or intellectual property office or from an intellectual property professional. Consult our list of intellectual property offices.

Also, please keep in mind that patent applications are generally not filed for a complete commercial product. Final products usually incorporate many separate innovations by different inventors. Indeed, the product may even contain technologies for which no patent application has ever been filed.

The default search field in the Advanced Search interface is EN_ALL. It is recommended to enter a field when using the Advanced Search interface either by typing the full name of the field of interest and PATENTSCOPE will transform it into a field code or by consulting the field code list.

Enter this query: ANID:PL* in the Advanced Search Interface

Yes, enter this query in the Advanced Search Interface: CTR:WO AND DP:2016 ANDNOT PI:[* TO *].

Search Results

There is a limit of 10,000 results when you are logged-in using your WIPO account.

Up to 25 results can be analyzed. By default, the top 10 applicants, IPC codes etc. will be shown but this number can be increased up to 25 in the Options menu.

No this functionality is not available. You can do a print screen and then save it as html.

Chemical Structure Search

You need to login using the WIPO account.

Both exact and substructure search are supported.

The chemical compounds are indexed in SOLR using InchIkeys. InchI stands for International Chemical Identifier and the InchIkey is a 28 characters string representing in a unique way a particular chemical structure.

Translation Assistance

CLIR stands for Cross-Lingual Information Retrieval: it first finds synonyms for search keywords you enter and then translates those and your original query into 13 languages. There are 2 modes to use CLIR: automatic in which you only have to enter your search or supervised in which after entering your search, you will have to select the technical domains your search is related to, the synonyms related to your search and the relevant translations. Using the supervised mode, you can also define the part of the document in which you would like to perform your search.

CLIR is available in 14 languages (English, Chinese, Danish, Dutch, French, German, Italian, Japanese, Korean, Spanish, Polish, Portuguese, Russian, and Swedish).

A neural machine translation tool developed in-house and trained exclusively on patent documents. It can translate any patent documents from and to 18 different language pairs.











A sequence listing is a part of a patent application that contains detailed description of the nucleotide and/or amino acid sequences in the application.

Sequence listings are available by clicking on Sequence listing in the “Browse” menu. Sequence listings are published in the format in which they are received.
