On CAPS, 98% of the 53 members who have rated RPX believe the stock will outperform the S&P 500 going forward. These bulls include TMFTypeoh and TMFIPO2011.

This past summer, TMFTypeoh tapped RPX as a particularly potent opportunity:

Hang [on] to your hat, this one could get crazy! Business model looks solid, financials look solid. Should be a crazy trader in the short term due to the IPO, but I'm putting real money behind this Gem.

RPX even boasts a robust trailing-12-month operating margin of 33%. That's higher than that of other business service stocks like ADP (NYSE: ADP) (18%), Thomson Reuters (NYSE: TRI) (16%), and Fiserv (Nasdaq: FISV) (24%).

CAPS member TMFIPO2011 elaborates on the RPX bull case:

**An industry-disruptive business model that brings order and efficiency to the exciting world of patent litigation and assertion.
**A rapid growth engine, mixed with sticky customers and the recurring revenue they provide.
**A network effect is being born -- client growth means RPX collects more subscription fees, which leads to additional patents purchased, making … its services incrementally more valuable for each new client.
