摘要：The US patent system has been the subject of three recent, generally critical studies. One, particularly uncomplimentary, primarily faults a changed source of funds for patent examination and creation of a court that, aside from the Supreme Court, has exclusive jurisdiction to consider patent appeals, both administrative and judicial. This paper explains why neither criticism is well taken. It also analyses reactions of the US Congress and Supreme Court to allegedly new problems caused by so-called patent thickets and patent trolls.
