The Intellectual Property (IP) & Science business of Thomson Reuters has announced the 50th anniversary of Derwent World Patents Index (DWPI), its flagship, proprietary database that is the world's most trusted source of patent information. This announcement marks the start of a year long celebration in honour of DWPI, as well as the inclusion of the 50th data source in DWPI: Indonesia. On this milestone anniversary, DWPI continues to provide professionals with authoritative, editorially enhanced patent data from 48 worldwide patent authorities and two literature sources.
The Thomson Reuters DWPI database enables professionals to more easily research and understand the world's innovations through editorially curated, English-language abstracting and indexing of patent documents. Today, DWPI covers more than 23 million inventions (basic records/patent families) detailed in over 50 million patent documents and is used by more than 40 patent offices worldwide.
DWPI's reliable and enhanced patent data contains many key features that distinguish it as the most trusted source of patent research information available. Patent records contain descriptive titles, abstracts summarising an invention's novelty using industry terminology, and corrections to important bibliographic information, including misspelled assignee and inventor names, erroneous priority data, missing classification codes and more. An expertly trained staff of several hundred editors applies over 5,000 rules to normalise, standardise, correct and enhance patent records resulting in approximately 6,000 corrections each week.
DWPI also features unique coding and indexing systems that are intellectually and consistently applied across all patent authorities and technologies allowing for precise, relevant and accurate retrieval of information. The intensive editorial process and quality checks result in authoritative and accurate patent data giving users insights that might otherwise be missed.
Derwent World Patents Index provides a complete view of activity in emerging and growing markets with global patent coverage in English, including the Asia-Pacific region. The country coverage was recently enhanced with the inclusion of records published by the Indonesian patent office. The latest addition brings the coverage in DWPI to 50, further extending the global footprint of its editorially enhanced content. The new Indonesian coverage includes all patent applications and short-term patents published from January 2011 to present.
