Question

patent laws create a dilemma. the idea behind patent protection is to provide inventors, entrepreneurs, and firms an incentive to innovate and develop new products and ideas. however, the incentive provided is to reward the innovator with the temporary ability to earn monopoly profits, which creates deadweight losses.
which policy is most likely to preserve socially desirable incentives to innovate while also reducing inefficiencies?
introducing a system of patent buyouts. the government would purchase most patents from inventors and then
ip up\ the patents so that others could immediately use the ideas; thus, prices would fall.
reducing the duration of patent law protection. this would allow firms to recover the costs associated with developing a new product but prevent firms from earning outlandish profits.
eliminating patent protection altogether. many existing firms make profits without the benefit of patent law protection, implying that firms would be able to discover other ways to profit from their innovations.
varying patent protection according to the significance of the good. for products associated with public health, like potentially life - saving medications, patents would not be enforced as strictly. patents for products with only commercial uses would be enforced as usual.

Explanation:

• 专利保护旨在激励创新，但会产生垄断利润和无谓损失。
• 减少专利保护期限，既能让企业收回研发成本（保留创新激励），又能防止企业获取过高利润（减少低效）。
• 专利买断系统中政府购买和废除专利，可能打击创新积极性；完全取消专利保护，企业创新动力不足；按产品重要性差异化专利保护，执行复杂且可能不公平。

Answer:

Reducing the duration of patent law protection. This would allow firms to recover the costs associated with developing a new product but prevent firms from earning outlandish profits.
