What does USPTO stand for?

The correct answer is the United States Patent and Trademark Office. This name accurately reflects the official government agency responsible for managing trademark registrations, as well as issuing patents. The office plays a crucial role in protecting intellectual property rights in the United States, overseeing the trademark application process, maintaining the official register of trademarks, and ensuring compliance with trademark laws and regulations.

The other choices provided do not correctly represent the agency's name or functions. For example, "United States Patent and Trademark Organization" misstates the official title by using "Organization" instead of "Office." Similarly, "United Safety Patent and Trademark Office" incorrectly introduces the term "Safety," which is not relevant to the office's duties. Lastly, "United States Protection of Trademark Office" misses the correct terminology and structure by omitting the word "Patent," which is also a key focus of the agency. Thus, choice C is the only answer that correctly identifies the official agency involved in patent and trademark matters.
