Final answer:
The 20-year patent period may be appropriate for a simple invention like a can opener, but may not be sufficient for complex inventions like a brain cancer cure.
Step-by-step explanation:
While patents provide an incentive to innovate by protecting the innovator, the length of the patent period is a topic of debate. The 20-year time period is somewhat arbitrary.
For Jack, who invented a new can opener, a 20-year patent may be appropriate. Can openers are relatively simple and can easily be replicated or improved upon by other inventors within a relatively short period of time. Therefore, a 20-year patent allows Jack to earn a good return on his invention without creating a monopoly.
On the other hand, for Jill, who invented a pharmaceutical that cures brain cancer, a 20-year patent may not be appropriate. Brain cancer is a serious and complex medical condition, and it may take a significant amount of time and resources to develop and bring a cure to market. A 20-year patent may not provide enough time for Jill to fully recoup her investment and earn a profit. In addition, a 20-year patent may limit access to this life-saving medication for those who need it.
