A patent is an industrial property certificate that certifies a technical invention as new, involving an inventive step, and being industrially applicable.
A patent grants the inventor exclusive rights over the invention for a specific period (generally 20 years).
These rights include preventing the unauthorized manufacture, sale, use, or import of the invention.
For an invention to be granted a patent, it must meet three main criteria:

| Inventive Step | Must be a technical solution not obvious to a person skilled in the field |
| Industrial Applicability | Must be producible or applicable in industry |
| Feature | Patent | Utility Model |
|---|---|---|
| Protection Period | 20 years | 10 years |
| Examination Requirement | Yes (Search + Examination) | No (Search only) |
| Scope | Includes product, process, chemical composition | Excludes process/chemical composition |
| Cost and Duration | Higher and longer | Lower and shorter |
