Abstract: A subscription social networking platform for the purchase and sale of IP assets between two subscribers includes an e-commerce platform, content analysis engine and database for storing vendible IP assets loaded by the subscribers. The content analysis engine determines the category of IP asset being loaded into the database. Any subsequent dialogue between any two subscribers about a particular category of IP asset will cause a search engine to search the database for relevant IP assets in that category for placement on a negotiation list. The two subscribers can thereafter negotiate the sale and purchase of the IP asset in a secure manner.
