I have tried this site now for the past 1 yr and its not really bringing any adequate revenue, hence I propose the following changes in terms of the business model.
1. To remove the registration for buyers
2. Remove the internal messaging option
3. Patent sellers will have to pay to list their invention and their contact details will be displayed
4. The free option is to be removed
5. Redesign of home page
Please also find attached snippets to the changes and I welcome your feedback and proposal also.
