Shares of InterDigital (Nasdaq: IDCC) hit a 52-week low last week. Let's take a look at how the company got there to find out whether cloudy skies remain on the horizon.

How it got here
InterDigital's been the very picture of a company that lives and dies by the buyout rumor over the last year. About a year ago, the patent-portfolio player got swept up in a frenzy whipped by major mobile players. For a while, it looked like Google (Nasdaq: GOOG) might sweep in and be the company's white knight, but InterDigital never recovered after Big G set its sights on Motorola Mobility instead. Two consecutive disappointing earnings reports in 2012 kept the pressure on InterDigital's stock, and it's been almost entirely downhill for months:

Of the major patent-portfolio players, only VirnetX (NYSE: VHC) can truly claim to have done well in the past year, and that gain's been almost entirely built on anticipation. The company hasn't generated any real revenue for a long time, but the faint possibility exists that VirnetX might win a windfall from Apple (Nasdaq: AAPL) if the House of Jobs is found to have used VirnetX's patented VPN technology.

What you need to know
InterDigital isn't the worst-performing, patent-portfolio company, but it does have the lowest expectations. Analysts have predicted that the company's earnings will reverse course over the coming years, while others' are projected to grow:

Company

TTM Revenue

Projected 5-Year Growth Rate (annualized)

Net Margin (TTM)

InterDigital $292.6 million (23.2%) 26.3%
VirnetX $3,000 15.0% NM
Rambus (Nasdaq: RMBS) $312.7 million 10.0% (21.3%)

Despite being the only one of three with positive earnings, as well as a decent 1.8% yield, InterDigital has been left for dead by market pros. The company's plans to sell off its patents haven't convinced the market that it's anything other than a value trap. There may be hope ahead for InterDigital if it can wrangle royalties out of companies building the "Internet of Things". But if Rambus' long and frustrating court fights to defend its intellectual property are any indication, smaller patent players might just wind up against a classic delay defense from the tech sector's big boys until their options run out.

What's next?
Where does InterDigital go from here? That may depend more on companies like Apple and Google than on anything InterDigital itself can come up with. My fellow fool Anders Bylund feels like the patent gold rush is over, which would spell doom for investors hoping for a future buyout or monster licensing deal.
