Commercial success is not a requirement for patentability. An invention can be patented even if it has not been commercially successful.

The utility requirement for patentability is that the invention must be useful. This means that the invention must have a practical application.

The novelty requirement for patentability is that the invention must be new. This means that the invention must not have been previously known or used.

The non-obviousness requirement for patentability is that the invention must be non-obvious. This means that the invention must not be obvious to a person having ordinary skill in the art.

The grace period for filing a patent application is 1 year. This means that an inventor has 1 year from the date of public disclosure or use of the invention to file a patent application.

The term of a patent is 20 years from the date of filing the patent application.
