How does the reasonable expectation of success requirement apply in unpredictable arts?

The reasonable expectation of success requirement applies to all fields of invention, but it can be more challenging to establish in unpredictable arts, such as biotechnology or pharmaceuticals. In these fields, the level of predictability is generally lower, which can affect the analysis of obviousness. The MPEP 2143.02 provides guidance on this issue, citing relevant…

What is the relationship between prior art teachings and reasonable expectation of success?

The relationship between prior art teachings and reasonable expectation of success is crucial in patent examination. According to MPEP 2143.02, the teachings of the prior art and their specificity play a significant role in determining whether there is a reasonable expectation of success in combining or modifying references. The MPEP provides guidance on this relationship:…
