April 2012

Four main improvements have been made to the PATENTSCOPE system, in addition to migration to the latest major version of the LUCENE search engine:[5]

  • Response time has been improved
  • The NEAR operator has been extended to allow combination with other Boolean operators, and proximity distance can now be specified.
  • Improved highlighting including hit maps, stemming, and fuzzy searching support.
  • A Display of Query trees function automatically executes subsections of search strings and generates a statistical breakdown.

"Searching by keyword in the descriptions and claims of patents written in Chinese, Korean, Russian or Portuguese is now possible in PATENTSCOPE without prior knowledge of these languages."[10]

"PATENTSCOPE Search Service now includes the national patent collection of the Dominican Republic."[11]

March 2011

"Around 30,000 applications in Chinese from 1994 to 2011 and around 170'000applications in Japanese from 1979 to June 2008 are now searchable in addition to already searchable JP full-text XML applications. Furthermore, searchable descriptions and claims of applications in Korean and Portuguese are also available."[12]

"In the framework of the integration of the LATIPAT collection in the PATENTSCOPE search service, data from the following countries are now available: Chile, Ecuador, Honduras, Nicaragua and El Salvador.[13]

A machine translation tool "developed in-house at WIPO uses Moses open-source technology" and "allows users to translate the titles and abstracts of inventions from English to French and Chinese and vice versa."[14]

February 2011

PATENTSCOPE now offers a search interface in Korean.[15]

"The European Patent Office (EPO) patent collection is now searchable in PATENTSCOPE ® search system. More specifically the bibliographic data from 1978 to mid 2010 and the full text from 1996 to mid 2010 of the EPO collection are now available for search."[16]

January 2011

PATENTSCOPE now offers search interfaces in Spanish.[17] and Russian.[18]

PATENTSCOPE "now includes the national patent collections of Colombia, Costa Rica, Guatemala, Panama, Peru and Uruguay."[19]

December 2010

WIPO announced that PATENTSCOPE now offers a Japanese-language interface for its “Search International and National Patent Collections” page. The interface language for this page can be changed by selecting a new language from the "options" menu. Other available languages include Chinese, English, French, and German. For the original source of this news see the press release here.

November 2010

WIPO announced that Brazilian patent data had been added to its national collections search. At the time of this collection's introduction, Brazilian bibliographic data was available from 1972, and abstracts from mid-1989. Almost 150,000 OCR full text records were also available in the collection, although an earliest date of coverage for full text records was not provided. A minimal number of records were available as PDF facsimile images.[20]

Collections for Argentina (AR), Morocco (MC), Spain (ES) and Singapore (SG) were also added to the system.

August 2010

WIPO announced a better integration of Google Translate into PATENTSCOPE, allowing users to produce machine translations of patent descriptions and claims on-the-fly. All supported language pairs normally in Google Translate are available.[21]

May 2010

WIPO introduced a new cross-lingual search query generating tool to the PATENTSCOPE interface, which they have termed the "Cross-Lingual Information Retrieval (CLIR) facility." The tool uses a number of cross-lingual dictionaries built in house by WIPO to generate keyword queries in other languages. The language dictionaries are built by using correlation methods between languages from WIPO's corpus of patent documents. The tool also uses a technology discipline filter to help ensure that the meaning of the desired synonym is clear to the system, disambiguating among polysemic meanings. To further ensure that only desired meanings of a word are searched, the tool also generates a basic set of main IPC classes to be included in the search string.

The tool generates cross-lingual search queries in English, French, German, Spanish, and Japanese. Two additional dictionaries are in development for Chinese and Portuguese searching, but the dictionaries for these languages are not yet based on a large enough document set to give them an acceptably low error rate.

The CLIR tool can be accessed here.

For more information about this tool, see the Intellogist blog post on the subject, here. Further resources are available from the WIPO website at this page, and a brief tutorial is available here.

Data Coverage

PATENTSCOPE National Collections

As of November 2010, PATENTSCOPE's searchable national patent collections include the African Regional Intellectual Property Organization (ARIPO), Argentina (AR), Brazil (BR), Cuba (CU), Israel (IL), Mexico (MX), Morocco (MC), Republic of Korea (KR), Singapore (SG), South Africa (ZA), Spain (ES) and Vietnam (VN). These collections were developed jointly by WIPO and the national patent offices, under a WIPO initiative to help countries with developing IP offices produce electronic collections.


National Phase Entry Data Coverage

PATENTSCOPE currently offers national phase coverage for 43 countries and authorities. The complete coverage list is available here. As of December 2009, the latest additions to PATENTSCOPE's coverage are the African Regional Intellectual Property Organization (ARIPO), Belarus, Hungary, Malaysia and the Eurasian Patent Organization (EAPO).[22]


The International Application Search Interface

The International Applications search service offers full text searching of its collection of Patent Cooperation treaty (WO/PCT) applications, and supports searching in both Latin and non-Latin text languages. The service currently supports full-text data search in the following languages: English, French, German, Japanese, Korean, Russian and Spanish.


The International Application Search Interface.


Some of the data in PATENTSCOPE may have been created electronically, while other information has been digitized to create searchable text. The following statement from the July 2009 PCT newsletter provides further information: "...in the case of those languages which use Latin characters (English, French, German and Spanish), where the original text is not in XML format, the searchable text format is obtained by applying Optical Character Recognition (OCR) procedures to the scanned images of the document."[23]


The National Patent Collections Search Interface

In September of 2009, a new patent search service was launched by WIPO for testing. This service allows users to perform free searches within national patent collections gathered by WIPO. A press release for the new service stated the following:

This new search tool, now available for public testing, allows you not only to search the PCT database of about 1.6 million International Applications but also the patent collections of ARIPO, Cuba, Israel, Korea, Mexico, Singapore, South Africa and Vietnam. This search facility features: flexible search syntax; automatic word stemming and relevance ranking; as well as graphical results.[24]

In September of 2009, a press release from WIPO stated that an agreement had been reached with the Kenyan government to digitize their patent documents, and disseminate them via PATENTSCOPE. However, a timetable for this project was not given. The article also stated that similar projects may be planned for Brazil, Peru, and Morocco, in addition to the collections already mentioned. [25] As of December 2009, PATENTSCOPE has added national phase information for the African Regional Intellectual Property Organization (ARIPO), Belarus, Hungary, Malaysia and the Eurasian Patent Organization (EAPO).[26]


The National Patent Collections Search Interface.


The service is notable for its extensive settings page, where users can control both the query input language and the interface language, in addition to a host of other display-related settings. There is even an option to control the "skin" or color scheme of the application.

After searching, it becomes apparent that one unique feature of the service is the way that results can be represented. A number of statistical measures are shown for the results sets, and these can be displayed as tables, bar graphs, or pie charts.
