Available Full Text Coverage
United States (US)
PatBase offers a comprehensive collection of full text US published applications, beginning on March 15, 2001.
Full text coverage of US granted patents is included from March 7, 1950 to date. It includes utility patents, plant patents, and re-issues. It also includes defensive publications and statutory invention registration (SIR) documents. Granted US design patents are covered from July 19, 1977 to present.
PatBase provides a unique interface feature for viewing full-text US patent claims. A “smart claims” option is available which will organize full-text claims into a claim map, showing the relationships between independent and dependent claims. The smart claims view is now also available for publications from all countries with full-text available. More is said about this feature in Viewing Full Text.
According to the latest full-text coverage chart on PatBase, the system now does contain full-text US patents from March 7, 1950 to the present. Test searches of granted patents prior to 1970 reveal that keyword searching is available within granted US patents from the 1950s and 1960s. The PatBase collection therefore now contains searchable electronic text for pre-1971 US patents. The ability to search in these older records is of special importance for mechanical searches, because mechanical concepts were being patented long before the advent of more recent technologies like computer science.
European Patent Office (EP)
Full text EP published applications (A kind codes) are provided from December 20, 1978, and full text granted EP patents (B kind codes) are provided from January 09, 1980.
In February of 2008, the system announced that their EP full text collection has been enhanced with in-line chemical structure images and other non-text data. In short, these chemical images, tables etc. will appear in the electronic text, at the same location they normally would have in the original patent copy.
Like other search engines, Patbase will not have full text records for EP applications representing those international PCT applications which enter into the EP regional phase (Euro-PCT transfer cases). However, PatBase is uniquely suited to remedy the Euro-PCT transfer problem: because PatBase hits are searched and represented by family, the PCT equivalents will always be included and searched in place of the EP document. (In other words, the way that PatBase is structured means that EP and WO collections will be searched together automatically.)
Patent Cooperation Treaty or PCT (WO)
Full text records of published PCT applications (WO documents) are included from October 19, 1978 to date for those documents published in a language that uses the Latin alphabet. Although the World Intellectual Property Organization (WIPO), which oversees the PCT application process, recognizes 10 official languages, in most electronic PCT collections only about 75% of the actual body of PCT documents were represented by electronic full text: the documents filed in English, French, German and Spanish (in 2007). This is because there has historically been more difficulty digitizing languages written in non-Latin alphabets via OCR. However, beginning in 2008, PatBase began adding non-Latin text data for some PCT documents originally published in non-Latin text.
As of November 2011, Russian-language PCT documents are covered from July 23, 1992 to date (with some gaps). Japanese-language PCT documents have some coverage from 1996 to date, but more complete coverage begins from July 2008. Chinese-language PCT documents have coverage from January 2011 to date, and Korean PCT documents have some coverage from June 2009 to date.
See the non-Latin text section for more information on searching the non-Latin data coverage in PatBase.
The addition of non-Latin text PCT records is a notable step forward for this collection, and may raise the bar on the coverage expectations for PCT collections in the future. This data also represents unique content for PatBase over other commercial systems. The free search system Patent Lens also offers some full-text searching for non-Latin PCT records in Chinese, Japanese, Korean, and Russian.
Like other search providers, PatBase’s PCT collection was produced by OCR software; some garbled characters may exist in the electronic text.
In 2008, PatBase released a collection of Japanese full text published applications, which has since been extended back to January 06, 1998. Some registered utility models are available in full-text from May 1, 1991 to December 17, 2009. The collection seems to be kept fairly current, about six-eight weeks behind the current date. It includes both "clipped" (representative) drawings and embedded images.(Clipped images are representative images taken from the patent drawing pages, while embedded images appear within the patent text. Embedded images appear in the PatBase electronic text in the same place as in the original patent.) A collection of Japanese-language Patent Cooperation Treaty (WO/PCT) applications has also been added.
In October 2008, the Japanese-language collections became searchable in PatBase (see the section on the Non-Latin Text Search Form for more information). Because the Japanese language is a “non-Latin” language, the text is accessed in PatBase via a slightly different route than text sections in Latin languages (see Viewing Non-Latin Text Records for more information). Finally, the Japanese full text sections can be translated into English using a machine translation feature within PatBase (See Machine Translations for Non-Latin Text for more information). According to the latest data coverage chart, searchable full-text machine translations for Japanese patent documents are available from January 1998 to September 2011, with some searchable full-text machine translations available from 1992.
Individual records of Japanese text may be machine translated into English "on-the-fly", although highlighting algorithms cannot be applied to it.
PatBase also includes F-I and F-term Japanese classification marks in its database. This classification data is updated in PatBase every two weeks.
PatBase is one of the first commercial search providers to begin making original text available for documents published in non-Latin languages. By extending its full text collection to Japanese, Chinese, Korean, Thai, Taiwanese, and Russian-language documents, PatBase is playing a valuable role in the patent search market. This is true especially because Asian countries are accounting for an ever-larger percentage of patent filings and are becoming increasingly more important sources of prior art.
An initial collection of partial-text original language Chinese documents was added to PatBase in early 2008. Coverage for CN patent applications is September 10, 1985 to present, and coverage for patents is January 5, 2005 to present (title, abstract and first claims are available). Utility model application coverage is April 4, 1985 to December 30, 1992, utility model coverage is January 6, 1993 to present, and designs coverage is September 10, 1985 to present. The most recently published documents in this collection are less than a week behind the current date, according to the latest full-text coverage chart. The patents do not contain the complete full text of the original language data: title, abstract, and first claims are included, while description sections are not included. Full-text, searchable machine translations are available for CN patent applications, utility model applications, and utility models.
In October 2008, this collection became searchable in PatBase (see the secton on the Non-Latin Text Search Form for more information). Because the Chinese language is a “non-Latin” language, the text is accessed in PatBase via a slightly different route than text sections in Latin languages (see Viewing Non-Latin Text Records for more information). Finally, the Chinese full text sections can be translated into English using a machine translation feature within PatBase (See Machine Translations for Non-Latin Text for more information).
In accordance with general PatBase practices, machine translated English abstracts are also included for those records without English-language family members. To learn more, see the Machine Translated Abstracts section of this article.
Full text French patent applications are available from January 2, 1981 to present, and utility model applications are available January 4, 1980 to present. Some full text patent applications are available from 1969 onwards.
The French text has been indexed without accents or diacritical marks and is often displayed in full text without these marks, which allows the advanced highlighting features to function correctly. For example, on a full-text search for “cable car” – PatBase retrieved FN = 30670898, a record with a French member originally containing the text “câble car.” However, the term “câble car” now appears as “cable car” in the French member of FN = 30670898, and the keyword highlighting function works correctly.
Full text German patent applications (DE-A) are provided from March 17, 1965 to date, and searchable full-text machine translations of the patent applications are available from January 1993 to present (the backfile is currently being loaded). German granted patents are available full-text from January 13, 1920 to present, and utility models are available full-text from August 31, 1961 to present.
The German text has been indexed without diacritical marks. The double “s” character, ß, should be searched as “ss”.
Unlike some competitors, PatBase does not have a full text collection of translations (DE-T).
A March 2007 newsletter asserts that PatBase also has a special agreement with the German Patent Office, allowing it to especially augment its German collection (it is implied that this will be done using OCR technology). In this regard, PatBase seems to be in direct competition with search provider Delphion, which previously boasted “the most comprehensive German collection available” because it provided bibliographic information, images and main claims for German from 1968 and full text from 1987. (It should be noted that Delphion is a legacy product, and the newest patent search product by Thomson Reuters is Thomson Innovation, which also has coverage of German granted patents and applications back to 1968.) Additionally, PatBase asserts that its German collection is updated with full text records the day after publication (more information about PatBase update schedules can be found on the Updates page).
Republic of Korea (KR)
In early 2008, PatBase added a collection of partial text Korean published applications. The published applications have been extended back to January 3, 1994, and some full-text applications are available from 1980 onwards. Granted patents are available from January 4, 1997 to present, and some full-text patents are available from 1980 onwards. Utility model applications are available from July 30, 1994 to present, and some full-text utility model applications are available from 1994 onwards. Utility models are available full-text from January 4, 1997 to January 5, 2011, and some full-text utility models are available from 1994 onwards. Design applications are available full text from January 21, 2010 to January 10, 2011.
Patent application, patents, and utility model applications are available within 1-3 weeks after the publication date, according to the latest coverage chart. Latest publication dates for utility models and design applications are both about 8-9 months behind the current date.
PatBase has announced the inclusion of "clipped" representative drawing images for these documents. (Clipped images are representative images taken from the patent drawing pages, while embedded images appear within the patent text. Embedded images appear in the PatBase electronic text in the same place as in the original patent.)
In October 2008 this collection became searchable in PatBase (see the secton on the Non-Latin Text Search Form for more information). Because the Korean alphabet is a “non-Latin” alphabet, the text is accessed in PatBase via a slightly different route than text sections in Latin-alphabet languages (see Viewing Non-Latin Text Records for more information). Finally, the Korean full text sections can be translated into English using a machine translation feature within PatBase (See Machine Translations for Non-Latin Text for more information).
In accordance with general PatBase practices, machine translated English abstracts are also included for some Korean records without English-language family members.
The additions of the Korean utility model collection in 2009 and designs in 2010 demonstrate PatBase's continuing commitment to expanding Asian full text data coverage.
United Kingdom (GB)
Full text patent applications from Great Britain are available from January 04, 1979 to date. A collection of granted patents is available from January 2, 1917 to March 12, 2003, and some full-text patents are are available from 1904 onwards.
This collection was at least partially produced by OCR technology. Some characters in the text may have been misinterpreted and garbled by the OCR process.
