Which of the following best describes a "patentable process"?

A patentable process refers to a method of doing something that involves a specific sequence of steps or actions that lead to a novel and useful result. This definition aligns with the criteria established by patent law, which requires that the process be new (not previously known or used) and non-obvious (not easily deduced by someone skilled in the relevant field).

In this context, the notion of a specific set of actions is critical because it emphasizes the structured approach required for a process to be considered for patent protection. This process must not only lead to a result but also establish a clear method that can be repeated and follows the necessary statutory requirements of being useful and innovative.

While a method that results in a predictable outcome could describe many processes, it does not inherently encompass the novelty and specificity required for a patentable process. The combination of existing technologies may yield new applications, but this does not explicitly define the structured steps needed to qualify as a process. Lastly, an innovative marketing campaign does not meet the criteria for a patentable process under patent law, as it typically relates to business methods rather than a scientific or engineering method that produces a tangible result.
