  GWD-8-Q7-Q10

The system of patent-

granting, which confers

temporary monopolies for

Line  the exploitation of new tech-

(5)   nologies, was originally

established as an incentive

to the pursuit of risky new

ideas. Yet studies of the

most patent-conscious

(10)           business of all—the semi-

conductor industry—suggest

that firms do not necessarily

become more innovative as

they increase their patenting

(15)  activity. Ziedonis and Hall,

for example, found that

investment in research and

development (a reasonable

proxy for innovation) did

(20)  not substantially increase

between 1982 and 1992,

the industry’s most feverish

period of patenting. Instead,

semiconductor firms simply

(25)  squeezed more patents out

of existing research and

development expenditures.

Moreover, Ziedonis and

Hall found that as patenting

(30)  activity at semiconductor

firms increased in the

1980’s, the consensus

among industry employees

was that the average quality

(35)  of their firms’ patents

declined. Though patent

quality is a difficult notion

to measure, the number of

times a patent is cited in

(40)  the technical literature is

a reasonable yardstick, and

citations per semiconductor

patent did decline during

the 1980’s. This decline in

(45)  quality may be related to

changes in the way semi-

conductor firms managed

their patenting process:

rather than patenting to win

(50)  exclusive rights to a valuable

new technology, patents

were filed more for strategic

purposes, to be used as

bargaining chips to ward

(55)  off infringement suites or

as a means to block

competitors’ products.

GWD-8-Q7 :

The passage is primarily concerned with discussing

1. a study suggesting that the semiconductor industry’s approach to patenting during the period from 1982 to 1992 yielded unanticipated results

2. 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

3. the connection between patenting and innovation in the semiconductor industry during the period from 1982 to 1992

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

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

前人就在AC纠结。我就不问了。

不明白的是B,其实全文都在说Ziedonis and hall的对这个industry的study, mgt towards patenting process也算说得过去，不同的策略安排。为什么就错了呢，请各位力求一针见血指出问题！

多谢啦！！
