Final answer:
Patent litigation serves to enforce patent rights and resolve disputes, thereby ensuring that inventors can benefit from their innovations for a limited time, which is typically 20 years. So, the correct answer is option b.
Step-by-step explanation:
Historically speaking, patent litigation has primarily served to enforce patent rights and resolve disputes between parties. The purpose of the patent system is to provide innovators with a temporary monopoly over their creations, which serves as an incentive for innovation by protecting their work from being exploited by others without permission.
The exclusivity granted by a patent—usually 20 years in the United States—allows the inventor to potentially earn monopoly profits from their invention, thereby recouping the investment made in research and development (R&D). This period of protection promotes further innovation by ensuring that the creators can benefit financially from their inventions, though the patent system's imperfect nature means that inventors may only receive a fraction of the total economic value generated by their inventions.
So, the correct answer is option b.
