SDG,
I generally stay away from the highly speculative stocks because those long shots with the most potential usually have the highest risk. So I keep my personal exposure to spec stocks very limited and stick to proven winners with strong earnings histories.
In the IP sector, these are the spec plays I either own currently or am following that I think have the highest potential investment return. Also, keep in mind these are all moving targets and new info changes things (as well as my analysis and opinions) swiftly. Not that I expect to sour on any of these, just take this with a grain of salt.
In no particular order...
MARA - owning this is like owning IPNav.com, some call it a junior version of Intellectual Ventures, the world's most hated patent troll company. MARA is making money actually and doesn't rely on high stakes patent litigation
DSS - strong patent portfolio in web 3.0/4.0 technology (think Facebook, Salesforce, etc) with lawsuits -- diverse practicing operations and small market cap. This one is litigation sensitive with several existing lawsuits ongoing
VHC - big opportunity to capture 4G LTE-Advanced royalties and secure domain services revenues starting in 2014-2015. Big lawsuit vs Apple already won for $368+ million, now waiting on judge to rule on ongoing royalty
BKYI - very risky, but I see potential here. Looks to be consolidating in the .20s... could be a long term winner
SPEX - I took a small position today. I'm optimistic this news today (with Rockstar) will have legs. Fundamentally, I am concerned there will be too many shares outstanding after the merger completes so I plan to either be a short-term owner or to sell enough to recoup my costs and free-roll the remaining shares
As always, I encourage those who want a long term investment in the IP sector to look at QCOM and ACTG - both proven winners. ACTG has far more upside, but also the riskier of the two. It reports earnings in a day or two so most might want to wait and see those numbers before jumping in.
