The Supreme Court unanimously decided a case the other day, overturning patents for something obvious. I've not read the patent, but it would seem that this fits into the "Obvious" category. That the patented idea might also be a good one, and offer benefits may not justify the patent. I also don't know whether it matters - it will depend upon whether the vendors who compete need this functionality and what the licensing will be. If it gives competitive advantage, but doesn't pay to fight, it will stand. If someone wants to fight, I suspect the patent will fall due to the court decision.
