ABET = Accreditation Board for Engineering and Technology
ABET accreditation for CS or engineering majors indicates that a program meets a fairly high minimum standard. However, it is considered optional for CS for most purposes (it is more important in engineering, particularly civil engineering), although a non-ABET-accredited CS major needs to be checked more carefully for its offerings of upper level CS courses and that it is a more technical CS major, rather than a less technical IT major in disguise.
But if you want to take the patent exam as a CS major, you either want an ABET accredited CS major, or you should follow the course selection guidelines in the patent exam requirements document linked in reply #6. Note that either case requires some course work in non-CS science that is often not required for non-ABET-accredited CS majors.
Emory’s CS department is small and has fairly limited upper level CS offerings compared to some other schools, although it is probably adequate.
