Description

As a part of the Web of Science search system, Derwent Innovations Index provides in-depth indexing of patents from 40 issuing authorities for the years 2008 to the present. Nearly all scientific and technical areas are covered including chemistry, electrical technologies, electronics, engineering, and other applied technologies. The database can be used to discover the latest technological advances, monitor competitors' progress, formulate fresh ideas for research, or get an overview of inventions in the global marketplace.

Powerful search features include left and right hand word stemming (truncation), e.g., ‘*degrad*’ that would pick up all words with that character string embedded therein (biodegradation, photodegradable, degradations, etc.) One can also build complex searching using Boolean logic use ‘OR’ to search for many synonyms/variant terms and ‘AND’ to combine any number of concepts.

For six major patent offices (U.S., Europe, PCT, Germany, Great Britain, and Japan), patents and articles cited by a given patent can be viewed, but not searched. Using the Advanced Search feature, citing patents can be viewed and searched by number, assignee, and inventor.

The Compound Search screen permits true substructure searching of chemical compounds via a drawing screen. Advanced searchers should make use of the detailed indexing provided in the International Patent Classification, Derwent Class Codes, and Derwent Manual Codes. For any result set, the most frequently appearing codes are displayed in the left-hand Refine Results column and can be used to further limit one's results. These codes can also be independently searched using the Search query screen. Careful use of the patent classes and special Derwent coding can greatly enhance the comprehensiveness of search results.

For more information, see the training videos and the Quick Reference Card provided by the database producer. More detailed information is available at Database Help Index. A useful, though dated, guide to the patent procedures and numbering systems used by different countries is the 2001 edition of the Derwent Global Patent Sources: An Overview of International Patents located in the Lockwood Library Science & Engineering Reference Collection, call number T210 .D47 2001.

Please refer to the University Libraries Patent Databases Research Guide for a detailed overview of searching both free and UB subscription patent databases.
