Bibliographic Coverage

In addition to the full-text patent databases, Dialog also offers several partial-text or bibliographic patent databases including:

File 344 - Chinese Patent Abstracts in English

(UPDATE: Since March of 2010, this file has been replaced by file 325, Chinese Patents Fulltext.^[1] See the Major Recent Updates section of this report for more information.)

This information is sourced from the Dialog Bluesheet for File 344.

Chinese Patent Abstracts in English is produced by the European Patent Office in cooperation with the Patent Documentation Service Center of the People's Republic of China. The file includes all patents published in the People's Republic of China since the opening of the Chinese Patent Office April 1, 1985 to the present.

Records in File 344 contain bibliographic information as well as English-language titles and abstracts. English-language abstracts are produced by the Patent Documentation Service Center of the Patent Office of the People's Republic of China. Patent family information is provided by the European Patent Office based on data contained in their INPADOC database.

According to Dialog documentation, file 344 tends to be updated on an irregular basis.

File 345 - INPADOC/Family and Legal Status

This information is sourced from the Dialog Bluesheet for File 345.^[2]

The INPADOC/Family and Legal Status Database (File 345), is produced by the European Patent Office (EPO) and describes patents issued by 80 countries and patenting organizations. The International Patent Documentation Center (INPADOC) was formed in 1972 with the support of the World Intellectual Property Organization (WIPO) to provide a centralized bibliographic source for patent documents. INPADOC is now part of the European Patent Documentation System operated by the European Patent Office (EPO).

The DIALOG version of the INPADOC database is unique in that it brings together equivalent patents that share common priorities for a particular invention in a single family record. The 34 million patent family records contain information on over 62 million patents and 44 million legal status actions. The newly reloaded version of Inpadoc also includes abstracts and search reports (cited patents and cited literature references) from key patenting offices such as the EPO, WIPO and the United States. Starting with week 200816, EPO's simple families and IDs, and a representative English abstract, if provided, are also available for browsing.

An INPADOC patent family record typically contains several kinds of data: the patent table, bibliographic data for each patent, and legal status actions if applicable. The patent table provides an overview of the family members and includes patent country, number, kind and date for each patent in the family, its corresponding local application number and date, and the week in which the patent was originally added to the database. Family priorities contain the application country, number, kind and date.

The bibiliographic data consists of patent title, generally available in one or more languages, patent assignees and inventors, International Patent Classification (IPC) codes including the recent IPCR/8 reclassification, European Classification (ECLA) codes, and national classification codes such as those used in the United States. For European and PCT patents, designated states are also provided.

Legal status actions are provided for 39 countries and include the patent number, the gazette date announcing the action, the legal status code, the equivalent text description, and the week in which the action was added to the database.

File 347 - JAPIO–Patent Abstracts of Japan

This information is sourced from the Dialog Bluesheet for File 347.^[3]

The JAPIO database, provided by the Japan Patent Information Organization, represents the most offers users English-language access to Japanese unexamined patent applications (Kokai Tokkyo Koho in Japanese) published since October 1976. All technologies are covered in the JAPIO database. Application records include both Japanese and non-Japanese priorities. Abstracts are provided only for applications originating in Japan, but are available for most records. Images of front page drawings, when available for a given patent, are also included. This file is updated on a monthly basis.

File 351 - Derwent World Patents Index

This information is sourced from the Dialog Bluesheet for File 351.^[4] There are two other related Dialog files, 352, which is a copy of the DWPI file for Japanese users only, and 350, which is the Derwent World Patents Index Extension, which is available for Thomson Reuters subscribers who have purchased access to several special features of the file.

Derwent World Patents Index® (DWPI), produced by Thomson Reuters, provides access to information from more than 30 million patent documents, giving details of over 14.8 million inventions. Records from 41 separate patent-issuing authorities are included in DWPI.

Each record in the database describes a single "patent family" containing data from the first publication of an invention, known as the "basic patent", as well as any further published patents relating to that invention, known as "equivalents". The records contain bibliographic data, Thomson Reuters-assigned titles, abstracts, general indexing and in-depth chemical and polymer indexing. Additionally, electrical and engineering drawings are present in records dating back to 1988, and chemical structure drawings are present in records dating back to 1992.

Starting in 1999, additional abstracts and indexing features are provided. The alerting abstract (formerly "basic abstract") is organized into paragraphs with informative, searchable paragraph headings. The alerting abstract also contains a Novelty paragraph describing the non-obvious improvements over previous technology. A Technology Focus abstract contains separate paragraphs providing different technological viewpoints of the invention.

The records in DWPI have been further enhanced with original publication data such as full author name and address, document title, abstract, claims, and legal representative. The amount of this original publication data present in each record varies by publishing authority, patent kind, and time.

File 351 is updated approximately twice weekly.

File 331 - Derwent World Patents Index First View

(UPDATE: As of July 2010, this file has been discontinued. See the Major Recent Updates section of this report for more information.)

This information is sourced from the Dialog Bluesheet for File 331.

Derwent World Patents Index First ViewSM is a companion database to Derwent World Patents Index®, Files 351 and 352, and also to Derwent World Patents Index Extension, File 350. It has been designed to be searched in conjunction with DWPISM to give a complete view of all the published patent documents before their inclusion in DWPI.

DWPI First View content is created by: • Identification of all patent documents added to the DWPI production system that have not yet been released into DWPI • Extraction of bibliographic information for these work-in-progress patent documents immediately after the DWPI patent family equivalency search • Addition of author text data such as title, abstract, and main claim for some patent-issuing authorities • Addition of technical drawing images where available • Release of these work-in-progress records as DWPI First View updates

DWPI First View is a rolling file. New patent records remain in DWPI First View until all of the value-add has been created by Derwent editors. The completed record is then added to DWPI and the corresponding DWPI First View record is removed.

DWPI First View is a patents-based database, whereas DWPI is family based. Each patent record in DWPI First View is identified as a Basic or Equivalent patent. Most of the records in DWPI First View are new Basic patents, as the majority of Equivalent patents are added immediately to DWPI, without having been in DWPI First View. DWPI First View contains records for those Equivalent patents that cannot be added to DWPI until the corresponding Basic patent record has been added to DWPI. There may also be a small number of Equivalent patents in DWPI First View for which the Basic is already in DWPI because of the timing of the extraction process for each file. These equivalents are likely to be transferred to DWPI in the next update. Equivalent patent records in DWPI First View list the corresponding Basic patent number.

File 353 - Ei EnCompassPat

This information is sourced from the Dialog Bluesheet for File 353.^[5]

Ei EnCompassPatTM (Engineering Information Patent Abstracts) contains patent documents relating to the petroleum, petrochemicals, natural gas, and energy industries. Data is sourced from the following bulletins of Patent Abstracts available in electronic format: Petroleum Processes; Petroleum & Specialty Products; Chemical Products; Environment, Transport & Storage; Petroleum Substitutes; Catalysts/Zeolites; Tribology; Reformulated Fuels; and Oilfield Chemicals. Coverage is worldwide. Before 1982, coverage was limited to patents issued by the United States, Belgium, Canada, France, West Germany, Great Britain, the Netherlands, Japan, South Africa, the European Patent Office, and the World Intellectual Property Organization.

File 353 is updated on a weekly basis.

File 447 - IMS Patent Focus

This information is sourced from the Dialog Bluesheet for File 447.^[6]

The IMS Patent Focus file pertains exclusively to pharmaceutical compounds. File 447 provides details relating to the evaluated product patent position for more than 3,000 commercially significant pharmaceutical compounds, both marketed or in Phase III (or above) clinical trials. The estimated patent expiry dates and the possibility of extension are also provided. Chemical structure searching is possible in this file using DialogLink 5 and a chemical structure drawing package.

File 123 - CLAIMS/Current Patent Legal Status

This information is sourced from the Dialog Bluesheet for File 123.^[7]

The CLAIMS®/Current Patent Legal Status file, provided by IFI CLAIMS Patent Services, contains post-issuance legal status information for U.S. patents. The data is sourced from the U.S. Patent & Trademark Office and from the USPTO Official Gazette. Coverage includes: certificates of correction, reassignment, reexamination requests and certificates, extensions, expirations, reinstatements, reissue requests, adverse decisions on interference actions, and disclaimer/ dedication data.
