- right to exclude others from making/using the invention without the consent of the patentee for a limited time
- Applies over a limited time period
- 20 years from the date of filing
Types of Intellectual Property:
- Industrial Design
- Trade Secrets
Where can I file?
- Patents granted jurisdictionally
- File in the jurisdiction in which protection is sought
- Regional patents
- International PCT system
- Patents issued by CIPO
- Patent examiners, under the Commissioner of Patents, analyze patent applications
- Granting of patents governed by the federal Patent Act (RSC 1985, c P-4)
Note: request for examination does not need to happen at same time as filing
The court must first determine:
- The state of the art as at the date of invention and the date of invention
The knowledge possessed by a person skilled in the art at the date of invention.
- Asserts that the idea expressed in the invention was already disclosed to persons skilled in that art
An alleged invention may fail the test of novelty on the following grounds:
- Anticipation by verbal disclosure or description;
- Anticipation by public show or exhibition;
- Anticipation by the existence of a prior patent or publication.
- A subjective test
- Must embody ingenuity
Indicators for ingenuity may include:
- A new “technical effect”
- “Surprise” the skilled but unimaginative technician
- Widely used in preference to alternative devices
- Have competitors or experts in the field ever thought of anything like it?
- Commercial success
- Industrial applicability
- Whether the invention performs as described or predicted by the inventor
- Tied to what the applicant claims in the specification.
Doctrine of sound prediction
- Utility as well as legal rights may be founded on the basis of logically predictive areas of the invention
- Art; knowledge, technology
- Composition of matter
- Scientific principles and abstract theorems;
- Ideas and Concepts; not embodied in an invention
- Methods of Medical Practice;
- Products of Nature;
- Substances intended for food;
- Accounting principles;
- Mathematical formulae;
- Rules of a game.
