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 semiconductor industries-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 semiconductor 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.

The passage makes which of the following claims about patent quality in the semiconductor industry?

A. It was higher in the early 1980's than it was a decade later.

B. It is largely independent of the number of patents granted.

C. It changed between 1982 and 1992 in ways that were linked to changes in research and development expenditures.

D. It is not adequately discussed in the industry's technical literature.

E. It was measured by inappropriate means during the period from 1982 to 1992.

------------------------------------------------------------

The OA is A I chose B.

In the given passage, a study that the auther mentioned analyzes two relation : one between R&D expenditures, the reasonable proxy of innovation, and the number of filed patent. Another is between R&D expenditures and the quality of the patent which can be measured by the number of times a patent is cited in the technical literature. And the study said, even a number of patent were filed in the given time, 1982 to 1992, the quality of the patents were not good. So I chose B.

Admittedly, the answer a is not fully wrong because early 1980's can be mentioned as 1980 or 1981, the time which is not metioned as the typical period in the passage.

Your opinion?

If you chose B then u must hv been very objective in reading the passage.

Although there are some specific lines which indicate that quality of the patents fell. The entire paragraph seems to suggest the same.

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

B - patent quality is independent of the number of patents granted.

"Yet studies of the most patent-conscious business of all-the semiconductor industries-suggest that firms do not necessarily become more innovative as they increase their patenting activity. "

this line suggests the reverse.. hence B is incorrect.

@arora007,

Your explanation gives me a new understanding about the topic.
I thought that the term "independent" is same with a term "irrelevant" because the quality and quantity of the patent can be manageable by mgt's strategy. But I guess i went so far as your saying.

Thanks a lot!
