an invention
The inventor invented an invention.
"Theft" is not a challenge for an inventor any more than it is for anyone else. Theft is taking something with the intention of permanently depriving its owner of it. Copying an invention is not theft because the inventor has not been deprived of the invention after it has been copied: the inventor still knows what the invention is. On the other hand, the risk of someone copying his or her invention is a challenge for an inventor. The person who copied the invention can get the benefit of the invention without any of the cost and effort that the inventor had to go to to make the invention. That might make the inventor worse off. The patent system exists to allow inventors to protect their inventions.
To provide an accurate answer, please specify the inventor and invention you have in mind. Without that information, I can't match them correctly.

The starting salary for an inventor is always zero. In fact inventors consume money for years and usually require a sponsor to invest in the invention. If you want to invent things with a salary, you become an engineer, working for a company, and the company owns the inventions.
