What right is associated with McDonald's slogan "I'm lovin' it"?

The association of McDonald's slogan "I'm lovin' it" falls under intellectual property rights, specifically trademark law. Intellectual property rights protect creations of the mind, which include slogans, logos, designs, and other branding elements that distinguish a company's goods or services from those of others.

In this case, McDonald's has successfully registered "I'm lovin' it" as a trademark, allowing them to exclusively use this catchphrase in their advertising and branding efforts. This exclusivity helps protect the brand’s identity and prevents other entities from using a similar slogan that could confuse consumers. The distinctive nature of the slogan is integral to McDonald's marketing strategy and contributes significantly to brand recognition and consumer loyalty.

The other options, like tort law and the doctrine of the proper law, deal with different legal principles that do not specifically relate to the protection and enforcement of trademarks or branding. Similarly, the Restatement conflict of law pertains to regional laws regarding jurisdiction and does not relate to intellectual property rights. Thus, the connection of McDonald's slogan to intellectual property rights is the most accurate and relevant choice.
