Index (abbreviated as DII) consists of DWPI and Patent Science Index (PCI).
Full text of patent! The full-text electronic version of this patent can be obtained directly from DII. Click the "Original" button next to the patent number in the record to obtain the PDF version of the full text of the patent. Thomson
PatentsStore provides more than 90% full-text patents in the world, supplemented by the index of DII patent family, which basically solves the problem of obtaining full-text patents.
Patent family! Derwent merged the same invention patent applied in different countries into one record, which prevented researchers from reading the same technological invention repeatedly after searching for patents, and saved valuable time for R&D personnel.
Collection scope! DII
More than180,000 basic invention patents and more than 38.9 million patent information from 4 1 patent institutions around the world (covering more than 100 countries, including China); The data goes back to 1963.
Quote information! Provide the most comprehensive patent citation information in the world. In addition to us, PCI also incluDEs WO, EP, JP, de,
GB patent citation data.
Accurate retrieval! The biggest difficulty in the utilization of patent information lies in retrieval. According to the full text of the patent, especially the patent claims, technical experts in various fields in derwent have rewritten the titles and abstracts with commonly used technical words to reflect the contents, applications, novelty and other information of the patent in detail, so as to help researchers search the patented technology quickly, accurately and effectively.
Readable! Through the titles and abstracts rewritten by derwent, researchers can know the details of patent technology in a short time, and avoid spending a lot of time reading and screening obscure patent full texts.
Flexible retrieval! Derwent's unique data deep processing indexing field provides researchers with accurate and fast retrieval ways, such as patentee code, derwent classification, derwent manual code, compound name, cited patent retrieval, etc.
Analysis function! The powerful analysis function of DII allows you to analyze as many as 100000 records in various ways, and analyze the development trend of technology, the distribution of patents and the distribution of patent technical details from different angles.
Language advantage: patent documents are published in dozens of different languages, which leads to a large number of missed inspections in single language retrieval and difficulties in subsequent reading; Through high value-added indexing, derwent has transformed dozens of different languages into readable and unified English, so as to avoid missing inspection and reading difficulties.
