SumoBrain Offers Free Registration

SumoBrain, the patent search system from the creators of FreePatentsOnline, is now offering free accounts. SumoBrain features full-text cross-collection searching of US patents and applications, EP patents and applications, PCT documents and Japanese abstracts, portfolios, alerts, and PDF download capabilities (for a fee). SumoBrain's content and search engine are very similar to FPO. And like FPO, registered users can save up to 1000 documents in 1-5 portfolios, and download bibliographic data from up to 250 records (at a time) in spreadsheet format.
