Scirus indexes patent data of 13 million patents

Scirus reinforces position as most comprehensive science-specific search engine.

Amsterdam, 22 March 2005 – Elsevier today announced that its free science-specific search engine, Scirus, has now indexed 13 million patents. Patents indexed in Scirus include those from the United States Patent and Trademark Office (USPTO), the European Patent Office (EPO), the Japanese Patent Office (JPO) and the Patent Cooperation Treaty (PCT) of the World Intellectual Property Organization (WIPO). By making patents available through its index, Scirus has expanded its service to include new and valuable information sources.

Scirus has a strong history of being the best tool for finding relevant scientific and academic information on the Web. The Scirus team recognizes the value of patent information to the scientific community as they provide insight into new technology trends and links to existing scientific information, enabling the community to build upon previous research and technology.

The patent index data included in Scirus is obtained via a unique alliance with LexisNexis, a Reed Elsevier company and leader in comprehensive and authoritative legal, news and business information. Patents are loaded in Scirus in close cooperation with LexisNexis, using Scirus’ up-to-date technology for indexing scientific information.

Scirus’ users can search for patents with the same fielded search capabilities as they have grown accustomed to when searching on Scirus. This includes the ability to search the index by title, abstract, author, date and affiliation. Users who require more in-depth patent searches are directed to specialized patent search tools offered through LexisNexis®.

The patents indexed in Scirus have been selected on the criteria of being either scientific in nature or relevant to the scientific community based upon categorization used by patent offices. Every patent search result found on Scirus provides a link to the full text at the appropriate patent office or to EPO's Esp@cenet (

“Scirus puts great effort into making sure deep Web sources, such as patents, which are not easily found in general search engines, are properly indexed and displayed,” said Ammy Vogtlander, General Manager of Scirus. “By making this important information searchable, Scirus remains the most comprehensive search engine for relevant and trustworthy scientific information on the Web.”

Patent searching, powered by Scirus, has also been added to Scopus, Elsevier's recently launched single Abstract and Indexing (A&I) database.
