Thomson Reuters Derwent World Patents Index celebrates 50!

Thomson Reuters announces a year-long celebration to mark the 50th anniversary of Derwent World Patents Index^® (DWPI^SM), a leading source of patent information, as well as the inclusion of the 50^th data source in DWPI: Indonesia. Originating in 1963, 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 contains many key features that distinguish it—descriptive titles, abstracts summarizing an invention's novelty, corrections to important bibliographic information, and unique coding and indexing systems, allowing for precise, relevant and accurate retrieval of information. An expertly trained staff of several hundred editors normalizes, standardizes, corrects and enhances patent records, resulting in approximately 6,000 corrections each week.
