Is it worth putting an extra year or two in your MBA to get a JD?
absultely especailly if you want to go into corp law or business law or patents for corprations.
If you want to go into business its a good idea. However, if you can do your JD full-time and the rest of the degree part-time, would be even better.
It is good not just from an IP persepective. IF you do that at a reputable place, you can come out and basically pick your job at any M&A shop in the country. Also, you could alernatively go for Corp strategy jobs in industry.
