In order to create this open content ecosystem, RPX will play a role in the success – it’s what is used to incentivize independent content producers to contribute to there site, ultimately building a great community of contributors and people with similar interests and objectives.
 
They are initially focusing on China’s capital markets because that’s what they specialize in currently, but having RPX to entice people to use our platform can help it expand much faster into a much larger and broader ecosystem.
 
They could do a traditional open content platform, such as Seeking Alpha or Xueqiu, but there’s the disconnect between what somebody produces on those websites and what compensation they receive. Those sites also run on advertising revenue. They are looking to RPX to disrupt that business model, and allow for higher quality producers to be paid for that content.
