Minesoft, founded in 1996, develops patent information services and solutions, linking technical, legal, bibliographic and full text patent information for patent professionals and research specialists. Minesoft's products and services are used by leading corporations, national Patent Offices, patent attorneys and law firms globally. Minesoft develops fast, effective document delivery solutions, a range of competitive intelligence services including patent alerting and monitoring tools, a patent family & legal status portal delivering the latest data for over 40 countries, a searchable patent database of over 48 million records, patent archiving, advanced viewing tools and more. In May 2003, Minesoft and RWS announced their agreement to develop PatBase, a new searchable patent database designed by experts in the complex art of search and retrieval of patent information. The first public demonstrations of PatBase in November 2003 received critical acclaim from expert patent searchers for the intuitive and feature-rich interface. PatBase is a comprehensive new search resource for patent and R&D specialists worldwide, covering 100 countries. Organised into extended patent families, each invention is represented by one individual record, making it easy to see in which countries a filing for patent protection has been made. PatBase is an ideal resource for conducting daily patent & technology searches. Rapid delivery of competitive intelligence, integrated searchable full text, PDF delivery and legal status reports bring PatBase to the forefront of today's searchable patent information tools. PatBase is regularly updated with new data and new search features and is now established as a leading patent resource. PatBase Express, developed in partnership with RWS and released March 2006, provides an easy-to-use end-user corporate-wide solution. PatBase Express allows the most up-to-date scientific research and competitor information contained in patent documents to be accessed throughout an organisation. Minesoft products can be customised to individual corporate requirements.
