What are the vertical-edge plates called? I'm assuming asking this question is ok since questions about kitchen equipment and cutlery are permitted.  

So far I've only found steel plates that have a vertical edge. Do these vertical-edged plates have a specific name that I could search for, to check if they are available as a microwavable plates?
  

Most plates are pretty flat, which causes food to annoyingly go off the edge and onto the table.
With Duarte's help, I found the plates are:  


Raised edge plate
The divided scoop plates.
Dignity plates.
High sided plates.
Hi Lo plates.
Manoy plates.
Inner lip plates.


There are also lipped edge plates, but it doesn't always satisfy the requirement of food not going off the edge.
