Welcome to the Latipat-Espacenet interface for patent document search in Spanish and Portuguese

What is the LATIPAT-Espacenet search interface: A free and public access point with Espacenet technology for the search of technical information in Spanish and Portuguese in patent documents of Latin American countries and Spain.

This interface and the data behind are the main result of the Latipat cooperation project launched in 2003 under the patronage of the World Intellectual Property Organization (WIPO), the European Patent Office (EPO) and the Spanish Patent and Trademark Office (OEPM), with participation of the national intellectual property offices of Argentina, Bolivia, Brazil, Chile, Colombia, Costa Rica, Cuba, Ecuador, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, Dominican Republic, Uruguay and Venezuela.

You are now in the "smart search" mode:

Here you can perform a simple search by entering query terms in the "smart search" box. If you want to perform a more detailed search, for example, using specific bibliographic data, select "Advanced search" in the left margin menu. If you select "Classification Search", you can browse and search the schemes in English of the CPC, the Cooperative Patent Classification, which is based in the International Classification IPC but more detailed. You can browse and search the IPC schemes in Spanish at .

The "smart search" is performed on the Latipat collection of patent documents. The keywords must be in Spanish and/or Portuguese. It does not matter if you use “tildes” (accents) or not. If you enter terms that are said the same way in Spanish and Portuguese (for example, bicicleta or plastico), the results will include documents published in both languages. If the terms are different in each language (eg. ventana / janela), the results will correspond only to documents published in the corresponding language. In this second case, if you want to retrieve all the documents in both languages, you must enter the keywords in the two languages between brackets and separated by the operator "or" (ventana or janela).

The patent documents are in PDF format. To display them you need Adobe Acrobat Reader or similar software.

In the "Advanced search" mode of Latipat Espacenet (by clicking on the menu in the left margin) you can search in five different collections of patent documents:

The first available collection for search is the aforementioned Latipat collection, which contains patent documents from 18 Latin American countries and Spain. The keyword search in the text fields of this collection has to be done in Spanish and/or Portuguese.

The second is the Worldwide collection, which contains patent documents from all the countries in the world which are included in Espacenet (the Latin American countries among them). The search by keywords must be done in English; the terms entered will be searched in the titles and abstracts.

The remaining three collections are Worldwide EN, Worldwide FR and Worldwide DE, which only contain documents published in English, French and German, respectively. The search by keywords must be done in the respective languages, and the terms will be searched in the titles, in the abstracts and also in the full text of the documents.
