The global standard in curated patent data.
Derwent’s editorial team comprised of domain experts spanning various technologies, provide clear titles and abstracts summarizing the novelty of the invention as well as correct errors in bibliographic data. Unique coding and indexing is also applied to every DWPI record.
More than 40 patent offices around the world provide us with their raw patent data and then purchase it back further enriched as a DWPI record to examine patent applications.
DWPI provides the most extensive view of patent activity in emerging and growing markets by providing the world’s most comprehensive collection of global patent data in English – more than 62 authorities covering over 30 languages. Nearly 86% of abstracted records in DWPI originate from non-English patent records.
Searching patents from many authorities can create massive data overload. DWPI patent families ensure you don’t encounter duplicate inventions. Our invention-based records allow you to see the full global protection for a single invention, instead of one record per patent – saving you valuable research time.
DWPI uses unbiased coding and indexing systems, which are intellectually and consistently applied across all patent authorities and technologies. Our unique coding and indexing system applies 20+ sections of Derwent classification and over 25K active manual codes to every record, providing unsurpassed searchability.
Within DWPI, users can easily conduct targeted searches of chemical patent data in the Chemical Patent Index (CPI). This data is also available through DWPI on STN.
DPCI provides an invention-level view of patent and literature citations, forward and backward and allows you to obtain all citations relevant to inventions or patent families. This unique lens on patent data allows you to gather comprehensive patent lists faster, freeing time and resources.
