I'm guessing that they evaluated the patents before Motorola got preliminary injunction against Apple.
IIRC, fewer than 2-3% of all patents actually survive and are upheld in patent trials, so they are not probably wrong when they say 48% of Moto's patents are worthless, but that isn't saying much. Take for instance, Apple's design and utility patents asserted against Samsung in Germany. All, 100%, of their patent and claims were invalidated, and declared worthless. I guess Moto's 48% is far better than 100% worthless. The key questions re: Moto's patents were their applicability, not their validity. Moto had filed lawsuits against Apple and Microsoft before Google bought it -- the court had to address Moto's appropriate FRAND licensing fee for SEPs (802 wireless standards and H.264 video encoding standards) and proper court jurisdiction.
IMHO, there is no reason to believe that Moto acquisition was a waste of money and, considering Android's popularity and success of Android today, despite threats from Apple's patent trolling (and even Microsoft), Google's strategy patent strategy worked well.
Wrong. Apple also sued Samsung for Android core features, but no infringement was found.
Microsoft was a tiny iceberg and exemplified what could have happened to Android. Samsung was reportedly paying close to $1B for a couple of years, until MS bought Nokia.
Google effectively neutered Apple's patent trolling operation by threatening to expose the troll's true motive, and prevented potential threat from Moto patent portfolio by preemptively purchasing it -- on the cheap.
