Questions: Now that the manufacture of PruBerry Bombe Tarts with less than 5 grams of psilocybin is legal, they are even more popular than ever. In order to increase the production of the tarts, Pru has invented a machine that will quickly and efficiently fill the tarts with the chocolate custard filling. A diagram of the machine is provided in Photo Exhibit 3. If Pru Berry believes the recipe for the PruBerry Bombe Tart is equivalent to a work of literature or artistic production, then Pru could attempt to protect the rights to that recipe through a: - Copyright - Trademark - Trade dress - Patent

The answer is: Patent

Explanation for each option:

1. Copyright: Copyright protects original works of authorship, such as literature, music, and art, but it does not extend to recipes. While the written description of a recipe can be copyrighted, the actual method of making the recipe cannot be protected by copyright law.

2. Trademark: A trademark protects brand names, slogans, and logos that distinguish goods or services. It does not protect the recipe itself but could protect the name "PruBerry Bombe Tart" if it is used to identify the source of the product.

3. Trade dress: Trade dress refers to the visual appearance of a product or its packaging that signifies the source of the product to consumers. This could include the design and appearance of the tarts, but it does not protect the recipe or the method of making the tarts.

4. Patent: A patent protects new inventions or discoveries. Since Pru has invented a machine to fill the tarts with chocolate custard efficiently, she could seek a patent for this machine. Additionally, if the recipe involves a novel and non-obvious process, it might also be eligible for a patent.

Therefore, the most appropriate form of protection for the recipe and the machine would be a patent.
