When was this product launched? Looks like these two are the first set of products launched by this company? Might be worth waiting for a while before putting this into an industrial embedded e;ectronics system?
Ambiq is actually a spin-off from the University of Michigan, though you are right that low voltage circuit design is a key area of expertise and IP at Ambiq. Ambiq's IP was developed by a group of leading low power researchers over the last 8 years and is wide ranging.

If I remember correctly, this is the spinoff from UIUC group working on subthreshold circuits. Any circuit with modifications to make sure, it works in the sub threshold region can be patentable. Meets the patentability criteria on novelty and non obviousness.
This will put the RTCs from the list of power hungry interface's list in the embedded systems, and designers will be able to make use of it efficiently, it will also help a lot in biomedical applications of embedded systems.
They seem to claim to have patented the RC oscillator, and also using a N channel MOSFET as a Power Switch ?
Amazing. Underlines why Patent reform is LONG overdue.
That aside, the numbers are impressive, but it seems they consider waving the patent banner, more important than telling anyone the price.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
