To deal with increasingly complex intellectual property questions, Congress established a specialized court and required that all statutorily defined "intellectual property" cases be filed there exclusively. Appeals are taken to a special intellectual property court of appeals and may, from there, be appealed to the U.S. Supreme Court. Is such an arrangement constitutional?
a) Yes, as Congress has the power to establish specialized courts
b) No, as it violates the separation of powers
c) Yes, as long as the Supreme Court retains appellate review
d) No, as it interferes with the judiciary's independence
