'067 is legally defensible, or at least strong enough to seek a settlement. The clauses are specific enough, especially compared to many other software and method patents (some by names as big as Apple) as well as arguably novel and non-obvious. The "inventor" has defined clear instances of applications which, although potentially broad, fit the specific terms of the patent.
The patent is clearly being asserted most aggressively against defendants who could easily have independently arrived at similar solutions. Having filed in 2001, it strains credulity that the patent could apply to smartphone apps (Android and the iPhone arrived in 2007). Given the vast number of accused infringements versus the actual R&D or tangible output of Uniloc, the company may fully deserve the epithet of "patent troll."
