Searching for ideas and thoughts to this part of my essay.You lean that a competitor has made an important discovery. It will substantially reduce, but not eliminate your profit for about a year. There is a possibility of hiring one of the competitor's employees who knows the details of the discovery. Would you hire this person or not hire this person?

No.

It's probably unethical to hire this person. Most companies have employees sign non-disclosure agreements that prohibits them from working for a competitor for at least a year after they leave.

If you have faith in your own engineers, then give them the task of finding new discoveries that would benefit your company.
Another thought --

Do you want an employee who would sell out his/her company to a competitor? Might this person do the same to you?
