What is the role of “sound scientific principle” in patent obviousness rejections?
Sound scientific principles play a crucial role in supporting patent obviousness rejections. According to MPEP 2144.02:
“The rationale to support a rejection under 35 U.S.C. 103 may rely on logic and sound scientific principle.”
This means that patent examiners can use well-established scientific principles to argue that a claimed invention is obvious. The use of sound scientific principles provides a logical foundation for the examiner’s reasoning. For example:
- If an invention is a straightforward application of a known scientific law or theory, it may be considered obvious.
- Examiners can use scientific principles to explain why certain modifications to prior art would have been obvious to try.
- Sound scientific principles can help predict the likelihood of success for combining prior art elements.
However, it’s important to note that the examiner must clearly explain how the scientific principle applies to the specific invention and why it leads to a conclusion of obviousness. Applicants can challenge such rejections by demonstrating that the application of the scientific principle is not as straightforward as the examiner suggests or by showing unexpected results that go beyond what the scientific principle would predict.
