问题 Business-method patents have recently aroused concern because of ______.
We learn from the last two paragraphs that business-method patents ______.
选项 A、are immune to legal challenges.
B、are often unnecessarily issued.
C、lower the esteem for patent holders.
D、increase the incidence of risks.
答案B
解析 本题是事实细节题。定位点在尾段第二句：Last April, for example, the justices signaled that too many patents were being upheld for "inventions" that are obvious．即：去年4月，该法院表明太多的专利都授予了一些极其明显的“发明”。就是说这种商业模式专利通常没有批准的必要性。
