In a very welcome move, IP Australia is upgrading its patent searching tool, known as AusPat. Apparently it will be capable of delivering up to "180 unique pieces" of information on each patent and patent application.
Full text searching is to made available by the end of 2010. A tool called "EDossier" will provide electronic access to a suite of documents relating to the prosecution of patent applications.
This new functionality will be a boon to the profession, particularly the smaller firms and sole proprietorships (yours truly).
