Why can derwent patent overcome the difficulties in patent retrieval in the past?

Personally, the most outstanding thing is that derwent patent database contains patent information rewritten by technical experts in various industries, such as descriptive title and abstract, novelty, technical key and advantages, etc. It avoids the missed detection caused by improper summarization and spelling mistakes in the original patent abstract of the patent itself. In addition, English abstracts of the latest patents in small languages (German, Japanese, French, Spanish, Arabic, etc.). ) provide it in time. Talk too much, such as advertising for free. ...

DWPI's deep processing data has many important characteristics, and it is the most reliable patent research information source in the industry today. Patent records include descriptive titles, summarizing the novelty of the invention in industrial terms, and correcting the information of important records, including correcting spelling errors, priority errors and missing classification codes of the names of patentees and inventors. Hundreds of professionally trained experts in various fields process 6,000 pieces of data every week according to more than 5,000 rules, including data standardization, normalization and correction.

DWPI also adopts a unique classification coding and indexing system. Technical experts use this method to manually classify and index the patents of major patent licensing agencies and all technical fields in the world, and follow the consistent classification principle to realize accurate and relevant information retrieval. In-depth and meticulous editing process and quality control ensure the authority and accuracy of patent data. If you don't use DWPI, you may miss some holes.
