Examples of Sequence Search Databases

GenomeQuest - "The first intranet sequence search engine with percent identity and biological searching. GenomeQuest works similar to premier web search engines, rapidly bubbling relevant records to the top. The software automates the reporting of the most important and relevant matches, minimizing tedious research, while providing advanced search algorithms so no relevant sequences are ever missed.”

Summary : Key points

No search service or database exists that comprehensively covers all patent information (yet)

Search services and databases differ in the search and analysis features they offer
