Derwent World Patents Index™ (DWPI) is the world’s most comprehensive database of enhanced patent information. Subject experts from Derwent’s editorial team analyze, abstract and manually index every patent record, making it easier for you to quickly find the information you need to make informed decisions. In DWPI, the use and advantage of a patent are clearly stated – not buried within an original patent document.
The Derwent World Patents Index is used every day around the world by patent professionals – from examiners to innovators and the attorneys who support them.
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 – 61 sources 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 consists of 20+ sections and over 25K manual codes, making it easy to locate the most relevant patent documents from the global patent corpus.
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.

Reducing the risk of missing relevant patents when searching for genetically engineered sequences.
Watch this webinar to learn how new biological therapeutic approaches such as CAR-T cell therapies present challenges for patent searchers. We will illustrate how new tools, such as GENESEQ™ on SequenceBase and Derwent Innovation™ can be used to reduce the margin for error during the patent search process, greatly increasing the speed and accuracy of your search for engineered sequences and the assessment of freedom to operate and actual infringement risk.
