Report:Derwent World Patents Index/Major Recent Updates

Major Recent Updates

See the Intellogist update policies for more information.

January 2013

The full DWPI Coverage Summary chart (PDF) has been updated as of January 2013. About half of the individual country coverage charts (alphabetically up to Luxembourg) on the Country Coverage and Kind Codes homepage also appear to have been updated as of January 2013.

Thomson Reuters has posted a Cooperative Patent Classification (CPC) – FAQ sheet (PDF) which includes the following information about the main features of the CPC implementation in Thomson Reuter’s products:^[1]

The CPC Backfile, which includes the pre -1920 US data (to the extent it has been supplied by the EPO and USPTO), will be loaded in 2013 Q1 for most of the products. In addition to the CPC new symbols the Backfile will also include the most up to date version of the IPC and ECLA (to the end of 2012). DWPI Backfile will be updated to include the second version of the Backfile supplied by the EPO at the end of January 2013 to include the CPC position indicator, a late addition to the CPC data. Therefore the DWPI Backfile with the position indicator will be available at the end of April 2013.

The ongoing CPC data from 2013 will be accessible in Thomson Reuters products in separate fields corresponding to its status: original for data issued at the time of publication (usually data extracted from the direct weekly data feed from the patent office and the CPC allocated by the national patent offices, CPCNO) and current for the most up to date version of the CPC for that record (usually data extracted from main exchange bibliographic file from the EPO or US reclassification feed).

According to the January 2013 issue of the Dialog Chronolog:^[2]

• Latest Manual Code revision goes live on Derwent World Patents Index (DWPI) - The Derwent World Patents Index® (DWPI) manual coding system annual revision for 2013 is now complete and is being used by the editorial teams to code records appearing in the database from DWPI Update 201301 onward. The editorial team consistently applies DWPI manual codes to new inventions across all 47 authorities (soon to be increasing) covered in the database. [...] In total, 235 changes have been made to the manual coding system and scope notes. Among them are 101 new codes.
• DWPI Country Update — Malaysia, Thailand, Indonesia - Derwent World Patents Index® (DWPI) has provided the following country enhancements:

  Additional Malaysia backfile

  DWPI began coverage of Malaysian granted patents (MY-A documents) at the end of 2010 starting with documents published in January 2010. The data now goes back to the beginning of 2005, and this data has now started appearing in DWPI as of update 201277. It will take several weeks before the backfile data is complete.

  Enhanced coverage of Thailand

  Coverage of Thailand is being enhanced to include registration numbers. These numbers are a five-digit serial number and will be indicated with the patent kind code TH-R0. They will begin to appear in DWPI in early 2013.

  As part of this enhancement, the date that is currently used for TH applications in DWPI will be the actual application date rather than the date of publication of the registration number as at present. The application dates can be over 10 years old and these are now starting to appear in DWPI.

  New coverage of Indonesia — the 50th data source in DWPI

  In early 2013, coverage of Indonesian applications (national and PCT transfers) and Simple Patents from 2010 to date will begin. This marks the 50th data source in DWPI (48 patenting authorities, Research Disclosures and International Technology Disclosures). Coverage will include DWPI titles and/or abstracts with CPI/EPI manual coding and chemical indexing for new basics.

• Start using the new Cooperative Patent Classification on Dialog - The CPC classes will begin appearing in INPADOC (File 345) and Chinese Patents Fulltext (File 325) in January 2013, but will be delayed in DWPI (Files 350, 351 and 352) until mid-March 2013. The search prefix for CPC codes is CP=. The accompanying attributes are searchable using CA= and can be linked to a particular CPC code using the (S) operator, e.g, S CP= A01F-0015/0833(S)CA=I.

According to an announcement on the DWPI users LinkedIn group:^[3]

As a result of the USPTO’s decision to delay the publication of the first patent applications with CPC classes on until March 17th 2013 there will now be a delay in the appearance of the first CPC information within the DWPI database. This will now not appear until the first quarterly update of INPADOC data which is expected in early March. The first US data will appear towards the end of March assuming this publication schedule is followed.

Thomson Reuters is now offering live online training entitled "CPC - The New Patent Classification System and Its Effects on Thomson Innovation and DWPI." Users can view the schedule of available courses and register here.

December 2012

This system has been updated since our last review. During our next scheduled update, this article will be revised to include a description of the newly added content and features.

The following updates to resolved issues involving DWPI were listed for Thomson Innovation Release 3.6 on December 16, 2012:^[4]

• Alerts - The DWPI Family and INPADOC Family fields display properly when editing alerts.
• Patent Record View - DWPI-First Claim displays properly for DWPI users without entitlements to Asian data.
• Patent Result Set - The Retrieve INPADOC/DWPI Family function works properly on results sets generated by Publication Number searches.

The following update was listed in the December 2012 Issue of STNewsline:^[5]

• Latest Manual Code Revision goes live on Derwent World Patents Index (DWPI) - The DWPI manual coding system annual revision has now been completed and is being used by the editorial teams to code records appearing in the database from DWPI Update 201301 onward. The editorial team consistently applies DWPI manual codes to new inventions across all 47 authorities (soon to be increasing) covered in the database. Since the coding highlights the novel technical aspects of the invention as well as the application(s), it is extremely useful to improve the precision and recall of searches and the subsequent analysis of result sets. [...] In total, 235 changes have been made to the manual coding system and scope notes. Among them are 101 new codes.

According to the December 2012 issue of the Dialog Chronolog:^[6]

• DWPI country coverage update — Changes to Gulf Cooperation Council (GCC) Kind Codes - As a result of customer feedback, the kind code for Gulf Cooperation Council patents in Derwent World Patents Index® (DWPI) has been changed from B to A to reflect that this is the first stage of publication for records filed through this patent office. From update 201260 onward, all new GCC patents have the kind code A, with back-file corrections subsequently appearing to change the kind code of records already in DWPI. DWPI users are encouraged to review any current Alerts or search strategies to ensure the correct patent kind is being searched.

November 2012

According to an announcement about the Cooperative Patent Classification (CPC) in the Thomson Innovation helpfiles:^[7]

CPC will be made available in most Thomson Reuters patent products and services and will be represented by new fields containing both backfile and frontfile CPC data. The old ECLA and USPC fields, while no longer updated, will be retained in Thomson Reuters products to allow reference to historical data.

Thomson Innovation will fully embrace this latest classification advancement with flexible and versatile features to allow searching, display, analysis, export, and alerting using CPC with their main defining characteristics (attributes). “Current CPC” fields will capture the latest status of the CPC for records and “Original CPC” fields will capture the classification information available at the time of publication.

DWPI users will also see and benefit from these classification changes including the refinements of the CPC data in the backfile as well as in the ongoing patent data. Technical documentation and data samples detailing the specific implementation in the DWPI feeds have already been sent to those users (and can also be obtained from our Technical Support team).

The CPC frontfile classification data will be available in January 2013 and the backfile data will be loaded in the first quarter of 2013.

Browsing tools and help files, as well as our training and product specialists, will provide assistance during the transition period so our customers can take full advantage of the benefits of this new classification system.

October 2012

This update has occurred since our last review. During our next scheduled update, this article will be revised to include a description of the newly added content and features.

The full DWPI Coverage Summary chart (PDF) has been updated as of October 2012. All individual country coverage charts on the Country Coverage and Kind Codes homepage also appear to have been updated as of October 2012 (except for Argentina, which was last updated in April 2012).

Thomson Reuters has released the latest coverage information for the Derwent World Patents Index. All individual authority coverage sheets are updated as of April 2012.

According to the CAS website:^[8]

The Numerical Property Search feature in the Derwent World Patent Index (WPINDEX, WPIDS and WPIX) on STN enables numerical searches to be performed for a specific set of physical property data identified within the English text fields.

Search field codes and related text for all physical properties available for numerical property searches have been indexed in the /PHP search field. Details on the newly available search fields and units are listed under HELP NPS.

For further information, please contact your local STN Help Desk.

The following announcement was released on the Delphion website:^[9]

In 2007, we launched Thomson Innovation® as our next-generation IP product with the goal of providing a solution that better serves the IP research and analysis needs of our customers. With its far superior patent coverage, best-of-breed search and analysis features, and enterprise collaboration capabilities, Thomson Innovation has enjoyed tremendous success in the market. Most of our former Derwent World Patents Index® (DWPI) on Delphion® customers have completed their migration to Thomson Innovation, and we are now announcing that DWPI on Delphion will no longer be available after March 31, 2012.

For more information, see this announcement on the Delphion website.

March 2012

This update has occurred since our last review. During our next scheduled update, this article will be revised to include a description of the newly added content and features.

According to a publication on the STN International website:^[10]

US application numbers consist of a two-digit series designation, corresponding to a range of filing years (i.e. series 08/ was used for filing years 1993 through 1997), plus a six-digit serial number (for example 635776).

In DWPI and DPCI, the format for US application numbers, for series up to and including series 12, excludes the two-digit series designation and comprises the application date along with the six-digit application serial,which starts again from000001 with each new series.

Series 13 Documents

The USPTO has now started publishing application numbers for series 13 with the first application in this series being filed on 17 December 2010. As an improvement to DWPI and DPCI, the series code element will now be included in the application numbers from series 13 onwards. There will be no change to the formats for any of the previous series.

See this publication on the STN International website for an example.

According to a publication on the STN International website:^[11]

Since the DWPI reload in 2006 on STN individual publication information has been covered. Customers requested that a display format be provided selectively displaying the individual publication data having given rise to the retrieval. This format has now become available as the HITMEMBer display format for the DWPI database (files WPINDEX, WPIDS and WPIX). This display format comprises all data from theMEMB format for all individual publications where HIT terms occur. An example may illustrate a possible user interaction.

See this publication on the STN International website for an example.

February 2012

Thomson Reuters has released the latest coverage information for the Derwent World Patents Index. According to the website,^[12] "Thomson Reuters sources patent data from 47 patent-issuing authorities and 2 journal sources to create Derwent World Patents Index® (DWPI)." The PDF documents listing the coverage data for each patent authority or journal source include the following information:^[12]

• The patent practices of 47 patent-issuing authorities (and two journal sources) worldwide — including their application and examination processes.
• The extent to which Thomson Reuters covers patents from each patent-issuing authority.
• Patent number and application number formats for Thomson Innovation and the key online hosts: Dialog, Questel and STN.

January 2012

According to the Thomson Reuters website, the 2012 revisions for the Electrical Patents Index (EPI) Codes and Chemical Patents Index (CPI) Manual Codes and Fragmentation Codes are now available.^[13] The website also states that:^[13]

As part of the 2012 DWPI Manual Code Revision process Thomson Reuters will be expanding the coverage of our manual codes to primarily enable mechanical aspects of packaging to be highlighted. From 2012 this new coding section will include manual codes covering novel features and applications of packaging and bottling equipment as well as novel packages and containers per se, that were previously only covered at the class level (classes Q31-Q39). The first Q3 code hierarchy is now available to download.

September 2011

According to the September 2011 issue of Dialog Chronolog:^[14]

The country coverage in Derwent World Patents Index® (File 351/352,350) has been further enhanced with the inclusion of records published by the patent office in Hong Kong. This latest addition increases the number of authorities covered in DWPI to 47, with 45.2 million patent documents, further extending the global coverage of editorially enhanced content in the file. Coverage will start from DWPISM update 201142. The new coverage is as follows:

• All Patent Applications, Granted Patents and Short-Term patents published from January 2011 ongoing.
• Records identified as basics will have DWPI titles and/or abstracts and manual coding, where applicable.

For more information, view this article in the September 2011 issue of Dialog Chronolog.

March 2011

According to a press release from Thomson Reuters:^[15]

The IP Solutions business of Thomson Reuters today announced that its Derwent World Patents Index® (DWPISM) database registered its 20 millionth invention, a patent record from Malaysia. [...] Thomson Reuters recently added the following content to DWPI, including English-language abstracts and titles:

• Granted patents from Malaysia
• Granted patents from Thailand
• Granted patents and utility models from the Philippines
• Patent applications and granted patents from Vietnam
• Patent applications and utility models from Russia

The 20 millionth invention in DWPI, filed as MY 140727A, is from IEV Group, a Malaysian oil and marine industry services company headquartered in Selangor on the outskirts of Kuala Lumpur. It describes a band-saw system for cutting pipes, such as oil pipelines, underwater, supporting Malaysia’s petroleum production and refining industry.

July 2010

Thomson Reuters announced that the Derwent DWPI First View file will be discontinued as of July 30, 2010. A Thomson Reuters press release explains that the First View file is no longer needed to provide access to newly issued patent documents, because the timeliness of the original DWPI file has improved. As of July 2010, records are added to the DWPI file within an average of 15 days after publication.

The First View file is described in the Derwent Families section of this article.

For more information, see Database News for May and June 2010 and The June 2010 issue of the Dialog Chronolog

June 2010

In June of 2010, Thomson Reuters representatives announced that Derwent assignee codes will now be used for any patenting entity with over 1,000 published patent documents.

Spring 2010

French Patent Coverage

Beginning in May 2010, the DWPI file will be enhanced with French granted patents (FR-B documents), which will be added to the existing collection of French applications on an ongoing basis. These FR-B's are expected to be mostly equivalents to basic family records already contained within the collection.

For more information see the May 2010 issue of STN Newsline.

Chinese Patent Coverage

The coverage of Chinese utility models in the DWPI file (file numbers 351, 350/352 on Dialog) is being extended to cover all published records from January 2007 to May 2007. Each record will have a full DWPI title and abstract and associated manual coding. As with the existing Chinese coverage in DWPI (which includes both applications and utility models), human translations of all the claims will be available at the DWPI member record level.

For more information see the May 2010 issue of the Dialog Chronolog

Swiss Patent Coverage

In response to a change in Swiss law, the DWPI coverage has been expanded to include Swiss patent applications (in addition to granted patents) back to January 2010. The file also includes other patent kind changes introduced by the Swiss patent office in July 2008.

For more information see the March 2010 issue of the Dialog Chronolog, and the March 2010 issue of STN Newsline.

Brazil and Spain Patent Coverage

In March 2010 it was announced that the DWPI producers were designating Brazil and Spain as "major" countries for the purposes of indexing, meaning documents from these countries would be treated by deep indexing procedures. The following excerpt from the March 2010 Dialog Chronolog details these enhancements:

Enhancements implemented to the coverage of Brazil and Spain are as follows:

-New coverage of utility models starting with records published in November 2009

-New coverage of granted patents starting with records published from January 2010

-The coverage of applications will be substantially improved with the introduction of enhanced DWPI documentation and alerting abstracts, and deep indexing of records with chemistry content. The enhanced coverage starts with records published from January 2010, and the same detailed level of coverage will also apply to Utility Models.

For more information see the March 2010 issue of the Dialog Chronolog and the March 2010 issue of STN Newsline.

2009

A Derwent Manual Code revision was slated for release in 2009. More about the recent manual code revisions can be found on the Thomson Reuters website.

October 2009

In October 2009, Chinese coverage in DWPI was significantly enhanced with hand-translated text content. English language abstracts and claims were added for Chinese (CN) applications and utility models on the member-level. Below is the text from the news announcement from STN:

From DWPI Update 200966 all the claims will be available in English at the DWPI member level for Chinese Utility Models published from June 2007 to date and for Chinese Applications (CN A) from January 2007 to date.

More information about this enhancement can be found on the STN International news bulletin page

September 2009

In September 2009, an announcement in the Dialog Chronolog stated that Indian Granted Patents coverage in Derwent World Patents Index is being extended by five years, back to January 2000. The processing of the backfile is underway, beginning with the records published in November 2004, and these records started appearing in DWPI update 200959.

The announcement further stated that records being loaded in the backfile are fully indexed to include Derwent Classes, Derwent Manual Codes, chemical indexing and enhanced polymer indexing, with chemical structures also covered in the Derwent Chemistry Resource.^[16]

January 2009

In January of 2009, the Derwent WPI files were enhanced to include Japanese classification codes, including both File Index (or F-Index) and F-Term codes. According to the announcement, "more than 5.25 million Japanese patents in about 4.5 million DWPI documents [were] enhanced with current Japanese classification data for 1966-2008."^[17] This data will be included for new records in the database from February 2009 forward.

October 2008

In October of 2008, the Chemical Abstracts Service (CAS) announced that PCT Applications entering the national phase from the Canadian Intellectual Property Office (CIPO) are now available in DWPI on the STN search platform from July 24, 2008 to the present. Coverage is based on the "Canadian Patent Applications" disks published by CIPO, starting with Volume 2008/001.^[18]

For more information about the document kind codes available for each patent authority collection in DWPI, see "Publication Kind Codes in STN Patent Databases," a manual produced by STN for the comparison of three STN databases: INPADOCDB (an STN version of the INPADOC database produced by the EPO), Derwent World Patents Index (called WPINDEX on STN), and CAplus (a proprietary chemical patent and literature database produced by CAS). The PDF version of the document is available at http://www.stn-international.de/training_center/patents/pkcodes.pdf.

September 2008

In September of 2008, the Chemical Abstracts Service (CAS) announced that DWPI on the STN search service now includes utility model registration documents from the Chinese patent office (SIPO), beginning with documents published on October 3, 2007. ^[19]

In addition, CAS announced that DWPI on STN would also include utility models from the Korean Intellectual Property Office (KIPO) beginning with documents published in January 2008. The news release stated that these Korean utility model records would include full DWPI value-added indexing, including DWPI titles, abstracts, manual coding, and deep indexing for records with significant chemistry content.^[19]

February 2008

In February of 2008, US national classification codes and ECLA classification codes (including in-computer-only or ICO codes) were retroactively added to DWPI.^[20]

The 2006 Reload

In 2006, major changes were made to the structure of the Derwent World Patents Index, and lots of new backfile data was added to extend the database coverage. Most notably, the reload marked the beginning of the new division of Derwent records into Invention (family) and Member (publication) data levels. This new structure was implemented to accommodate more data about individual family member documents. New "member level" data, added during the reload, included original titles, full inventor name and address, original assignee name and address, patent agent information, and US patent main claims. This data was added retrospectively, in some cases back to the earliest records in the database.

Before the 2006 reload, Derwent did not contain US, ECLA, or Japanese F-term classification data. After the reload, the system adapted to accommodate classifications that would be regularly revised and updated. Derwent began by adding original US classifications at time of publication in 2006, with the aim to add subsequent re-classifications of US, ECLA and F-term codes.

In addition, the reload added new application and priority numbers for patent family members (previous to the reload, this data was limited to only 10 priorities, and applications were captured from a limited number of document kinds and authorities). This extension of priority and application data makes date searching in the database more reliable.

The reload also saw the DCR structure searching capabilities, discussed below, extend throughout the database backfile. Before the re-load, the capability only extended back to the service’s introduction in 1999.

Finally, one improvement to database functionality was implemented with the reload: "stop words" restrictions were removed from the database, and common words became searchable. This improvement enables phrase searching where phrases contain common words – e.g. the phrase "Vitamin A" is now searchable in the database.
