Despite problems with the voting procedure, it is clear that every program on this list has an excellent IP program. And, although the list is not a “patent law program” list, all of the listed law schools employ at least one full-time faculty member whose primary teaching and research interest is patent law. Likewise, although you may quibble about individual rankings, there is no question that Berkeley’s program deserves to be very highly ranked.
