In the current legal environment, my guess is that a technology with patent licenses is nearly worthless compared to a technology with patents. Note that if someone wants to license webOS, naturally they license the patents. But who would want to buy the business but not the IP? That’s like licensing the operating system, being responsible for maintaining it, and paying a massive fee for the license up front. Such a business would be hard to run and hard to sell since you aren’t buying the IP and therefore can’t resell it.
