问题 Text 2 Over the past decade,thousands of patents have been granted for what are called business methods.Amazon.com received one for its"one-click"online payment system.Merrill Lynch got legal protection for an asset allocation strategy.One inventor patented a technique for lifting a box.Now the nation's top patent court appears completely ready to scale back on business-method patents,which have been controversial ever since they were first authorized 10 years ago.In a move that has intellectual-property lawyers abuzz the U.S.court of Appeals for the federal circuit said it would use a particular case to conduct a broad review of business-method patents.In re Bilski,as the case is known,is"a very big deal",says DennisD.Crouch of the University of Missouri School of law.It"has the potential to eliminate an entire class of patents."Curbs on business-method claims would be a dramatic about-face,because it was the federal circuit itself that introduced such patents with its 1998 decision in the so-called state Street Bank case,approving a patent on a way of pooling mutual-fund assets.That ruling produced an explosion in business-method patent filings,initially by emerging internet companies trying to stake out exclusive rights to specific types of online transactions.Later,more established companies raced to add such patents to their files,if only as a defensive move against rivals that might beat them to the punch.In 2005,IBM noted in a court filing that it had been issued more than 300 business-method patents despite the fact that it questioned the legal basis for granting them.Similarly,some Wall Street investment films armed themselves with patents for financial products,even as they took positions in court cases opposing the practice.The Bilski case involves a claimed patent on a method for hedging risk in the energy market.The Federal circuit issued an unusual order stating that the case would be heard by all 12 of the court's judges,rather than a typical panel of three,and that one issue it wants to evaluate is whether it should"reconsider"its state street Bank ruling.The Federal Circuit's action comes in the wake of a series of recent decisions by the supreme Court that has narrowed the scope of protections for patent holders.Last April,for example the justices signaled that too many patents were being upheld for"inventions"that are obvious.The judges on the Federal circuit are"reacting to the anti-patent trend at the Supreme Court",says HaroldC.Wegner,a patent attorney and professor at George Washington University Law School.29.We learn from the last two paragraphs that business-method patentsA.are immune to legal challengesB.are often unnecessarily issuedC.lower the esteem for patent holdersD.increase the incidence of risks
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 本题考查对后两段中关于business-method patents相关信息的理解。在末段二句的例证中指出“法官们传递出太多的专利被授予了那些明显的发明”，可见B项是对此句的同义置换，为正确答案。A项是就四段二句设置的干扰选项，属篡改文意；C项是对末段首句设置的干扰项，用esteem偷换了原文中的protection；D项是就四段首句中的risk编撰的无中生有选项。
