What represents a company's strategy to protect its unique products or services through legal means?

The correct answer is Patent, as it specifically pertains to a company's strategy for legally protecting its unique inventions, designs, or processes. A patent grants the holder exclusive rights to manufacture, use, or sell the invention for a limited period of time, usually up to 20 years. This legal protection encourages innovation by allowing the inventor to potentially recoup their investment and benefit financially from their invention without competition from others using the same product.

Other options predominantly relate to different aspects of intellectual property: a copyright protects original works of authorship, like books and music; a trademark safeguards brand names and logos that distinguish goods or services; and a franchise involves a legal agreement to operate a business under a franchisor's brand or business model, not necessarily linked to protecting a unique product or service itself. Thus, while each of these legal mechanisms plays a role in protecting various aspects of business, a patent is the most relevant when it comes to uniquely protecting a company's products or services invented by them.
