Why Search for Patents?
• Determine whether your invention is original or has already been patented
• Access information about the latest technologies which may not have been published in scholarly journals
• Access detailed descriptions and diagrams for millions of inventions
• Research patents registered by specific companies (for businesses, this could mean competitors)
• Manufacturers can search for licensing opportunities
