Boliven, a New York-based company, has launched a free patent database called Boliven Patents Beta.
The database contains data and images for US patents from 1976 to present, EP documents from 1978 forward, WO applications from 1989 forward and JP abstracts from 1976 forward. Search options include Basic, Advanced, Expert and Patent Number.
Search results can be filtered by source, assignee, date, and document type and sorted by relevance or date. A "QuickFlip" display option allows searchers to flip through displays of front pages very quickly.
Users who register for personal accounts (by invitation only) can take advantage of analytical tools, search histories, alerts and lists. For more information, see the press release.
