Google: The First Lemming Into The Nortel Patent Canyon

A patent cliff refers to a sudden, massive and potentially catastrophic series of patent expirations that negatively affects pharmaceutical companies.  A patent canyon, on the other hand, is something different, albeit similar (in geological terms) to a cliff (don’t bother googling it, I just made up), and it applies to the fabled Nortel portfolio. The Nortel patent canyon promises that if you fill up the canyon with enough cash, you can safely cross to the other side where you’re sure to find invaluable licensing opportunities, freedom to operate, a land flowing with milk and honey, and other valuable riches.
