Final answer:
Patent rights can be obtained through inventing, demonstrating utility, and proving novelty. Natural phenomena and abstract ideas cannot be patented.
Step-by-step explanation:
a) The following are three activities that can lead to the creation of patent rights:
- Inventing: Coming up with a new and useful process, machine, composition of matter, or design.
- Utility: Demonstrating that the invention has a practical and useful purpose.
- Novelty: Showing that the invention is new and unique, not something that has been done before.
b) Two items that cannot be patented are:
- Natural Phenomena: Natural phenomena, such as laws of nature or scientific principles, cannot be patented because they are considered to be discoveries rather than inventions.
- Abstract Ideas: Abstract ideas, theories, mental processes, or mathematical formulas cannot be patented as they are considered to be fundamental concepts that are not eligible for patent protection.
