Biopatents are exlusive right granted by a government to inventors or their assignee for a limited period of time in exchange for a public disclosure of an invention. Patents should satisfy the following criteria, except:

Options

A. novelty
B. utility
C. unpatented traditional knowladge
D. non-obviousness

Answer

To answer the question regarding the criteria that patents should satisfy, we will analyze each option provided and determine which one does not fit the criteria for obtaining a patent.

### Step-by-Step Solution:

1. **Understanding Biopatents**:
- Biopatents are exclusive rights granted by a government to inventors or their assignees for a limited time in exchange for public disclosure of an invention.

2. **Criteria for Patents**:
- Patents must generally satisfy three main criteria: novelty, utility, and non-obviousness.

3. **Evaluating the Options**:
- **Option 1: Novelty**:
- This means the invention must be new and not previously known or used by others. Since novelty is a fundamental requirement for patents, this option cannot be the answer.

- **Option 2: Utility**:
- This refers to the usefulness of the invention. The invention must have some practical utility. Since utility is also a fundamental requirement, this option cannot be the answer.

- **Option 3: Non-obviousness**:
- This means that the invention should not be obvious to someone skilled in the relevant field. This is another essential criterion for patentability, so this option cannot be the answer.

- **Option 4: Unpatented Traditional Knowledge**:
- This refers to knowledge that has not been patented. While traditional knowledge can be relevant in the context of biopatents, it is not a requirement for obtaining a patent. In fact, traditional knowledge is often not patentable itself, and thus, this option does not fit the criteria for patentability.

4. **Conclusion**:
- The correct answer is **unpatented traditional knowledge**. It is the only option that does not satisfy the criteria for obtaining a patent.

### Final Answer:
The criteria that patents should satisfy, except for **unpatented traditional knowledge**.
