Looking for feedback on my patent search engine/marketplace

I Recently launched a pretty interesting tool. ipcypris.com It's a search engine and marketplace for patents. Search engine is specialized for investigating a company's or inventor's patents. Patent owners can claim their patents and convert them to listings to offer the technology for sale or license. The search/filter combination is pretty valuable for drilling down a company's patents. Try 'Amazon' then filter into 'Aircraft & aviation.'. Would love to hear some feedback. Thanks! ipcypris.com
