The correct answer is D. All the above.
Novelty means that the invention must be new. It must not have been disclosed to the public anywhere in the world, in any way, before the filing date of the patent application.
Inventive step means that the invention must be inventive. It must not be obvious to a person skilled in the art, having regard to what was known or used in the art before the filing date of the patent application.
Capable of industrial application means that the invention must be capable of being made or used in any kind of industry.
These are the three main criteria that must be met for an invention to be patentable. If an invention does not meet all three criteria, it will not be granted a patent.
Here are some additional details about each of the criteria:
- Novelty: The novelty requirement is designed to prevent inventors from obtaining patents on inventions that are already known to the public. To be novel, an invention must not have been disclosed to the public anywhere in the world, in any way, before the filing date of the patent application. This includes disclosures made in publications, oral presentations, or even through the use of the invention itself.
- Inventive step: The inventive step requirement is designed to prevent inventors from obtaining patents on inventions that are obvious to a person skilled in the art. To have inventive step, an invention must not be obvious to a person skilled in the art, having regard to what was known or used in the art before the filing date of the patent application.
- Capable of industrial application: The industrial application requirement is designed to prevent inventors from obtaining patents on inventions that are not useful or practical. To be capable of industrial application, an invention must be capable of being made or used in any kind of industry. This includes inventions that are useful for a commercial purpose, as well as inventions that are useful for a scientific or educational purpose.
