题目信息

The system of patent-granting, which confers temporary monopolies for the exploitation of new technologies, was originally established as an incentive to the pursuit of risky new ideas. Yet studies of the most patent-conscious business of all-the semi-conductor industry-suggest that firms do not necessarily become more innovative as they increase their patenting activity. Ziedonis and Hall, for example, found that investment in research and development (a reasonable proxy for innovation) did not substantially increase between 1982 and 1992, the industry's most feverish period of patenting. Instead, semiconductor firms simply squeezed more patents out of existing research and development expenditures. Moreover, Ziedonis and Hall found that as patenting activity at semiconductor firms increased in the 1980's, the consensus among industry employees was that the average quality of their firms' patents declined. Though patent quality is a difficult notion to measure, the number of times a patent is cited in the technical literature is a reasonable yardstick, and citations per semiconductor patent did decline during the 1980's. This decline in quality may be related to changes in the way semi-conductor firms managed their patenting process: rather than patenting to win exclusive rights to a valuable new technology, patents were filed more for strategic purposes, to be used as bargaining chips to ward off infringement suites or as a means to block competitors' products.

A:a study suggesting that the semiconductor industry's approach to patenting during the period from 1982 to 1992 yielded unanticipated results

B:a study of the semiconductor industry during the period from 1982 to 1992 that advocates certain changes in the industry's management of the patenting process

C:the connection between patenting and innovation in the semiconductor industry during the period from 1982 to 1992

D:reasons that investment in research and development in the semiconductor industry did not increase significantly during the period from 1982 to 1992

E:certain factors that made the period from 1982 to 1992 a time of intense patenting activity in the semiconductor industry

主旨题
文章主要先提出了专利一开始是用来干嘛的（用来鼓励创新的），但是studies suggest 并不是这样的（申请专利活跃了之后，并没有变的innovative），然后举了个例子（Z and H) 整篇文章在讨论patent的影响，和innovation的一个关系
选项A the (semiconductor industry’s) approach yielded unanticipated results 讲的主要不是这个行业yielded unanticipated results，重点在patent和innovation上面
选项B a study that advocates certain changes in the industry’s management与文章主要内容不符
选项C 正确
选项D reasons that investment did not increase significantly 与文章主要内容不符
选项E certain factors that made the period a time of intense patenting activity 讲的主要不是这个事情专利申请活跃的因素，与文章主要内容不符
