The thermal conduction thru the steam would be the biggest heat loss and a simple lif would serve you much better than a fancy mug.  Milk foam also works well.

+Paul Gray Yeah, it's more the idea is interesting than something anyone would want.

This may be a successful project. There are at least two similar ideas on the market in the form of stainless steel widgets containing a material with a phase change around 140 degrees F. The material is "frozen" at room temperature and is melted by the hot coffee then refreezes as the coffee cools. My wife bought some of these gadgets at "Bed, Bath, and Beyond". It is quite likely that these mugs use a similar material as the "active" insulation.

I think this project is a scam. If they were using a phase-change material, they would be giving us details about its characteristics. Water has a very high specific heat, so you need a very effective phase-change material if you want the cup to make a noticeable difference.

You could make an unpowered self-balancing robot on the same idea: when dropped on a surface it winds up two flywheels and then releases their energy as needed to gain rotational momentum one way or the other if a damped pendulum swings off-center.
