Canadian law

Scenario:

Alice Silva worked at an egg grading station while completing her degree in business administration. The summer position piqued her interest in courses like statistics, operations management, and management science. When she graduated, she went back to work for the egg producer. This time, she was on the management side and put her education to use thinking about how some of the firm's processes might be improved. In particular, she was interested in how advancements in artificial intelligence and robotics might be used to enhance the grading and sorting processes. Silva's work ultimately led to the development of "Eddy," an egg grading robot. She remembered from her commercial law course that she should explore the opportunity to patent her invention.

Question: What are three things in the area of patent law that Silva may want to explore?
