On CAPS, all 68 members who have rated RPX believe the stock will outperform the S&P 500 going forward.

Earlier this month, one of those bulls, All-Star DaddioResources, tapped RPX (short for Rational Patent Exchange) as a particularly timely opportunity:

Rational patent is ultimately a response to the growing trend of patent litigation. ... Companies with patent concerns can manage this risk by buying a membership in Rational Patent.

RPX holds a portfolio of some 1,600 patents -- nearly all of them from marquee names from the high-tech sector -- and clients pay RPXC $60,000 to $6.6 million a year to license all of the patents and thus avoid trampling on anyone else's proprietary technology.

Rational Patent then uses its revenue to buy more patents, which attracts more members, and so it goes.

There are about 2,500 companies that could benefit from a membership, which gives RPX a huge amount of growth potential.
