This past summer, one of those Fools, All-Star BuffettJunior1, succinctly summed up the RPX bull case for our community:

RPX is a fast growing company in a niche industry: patent defense. The company provides a subscription-based patent risk management solution that facilitates more efficient exchanges of value between owners and users of patents compared to transactions driven by actual or threatened litigation.

The company's fundamentals are outstanding, which is surprising for such a young company (founded in 2008 and went public in May of 2011). ...

I also believe that RPX is developing somewhat of a competitive advantage or "economic moat." RPX's business model has a "network effect," because as the company adds new clients it generates new subscription fees that can be used to fund additional acquisitions of patent assets. These acquisitions enable RPX to add new clients and to deliver greater value to the company's existing clients. ...

Overall, I believe RPX is an outstanding business with lots of growth potential and currently selling (trading) at a very low valuation. Those who are patient will be greatly rewarded by investing in this stock.

If you want market-topping returns, you need to put together the best portfolio you can. Owning exceptional stocks is a surefire way to secure your financial future. Of course, despite its five-star rating, RPX may not be your top choice.
