What factors are considered to determine the "level of ordinary skill" in the art?

The determination of the "level of ordinary skill" in a particular art is a critical aspect in patent law, particularly for assessing the obviousness of an invention under 35 USC 103. This level of ordinary skill is evaluated based on several key factors that provide insight into the understanding and capabilities of a person having ordinary skill in that particular field.

Considering the educational background of the inventor helps to contextualize the level of skill that is typically associated with practitioners in that area. For instance, if the field generally requires a specific degree or training, this background can inform how a skilled person would approach solving problems within that art.

Prior art solutions are also pivotal. The existing knowledge and solutions available in the field of the invention set a baseline for what is considered common knowledge among skilled individuals. This helps to benchmark the inventive step against what has already been disclosed, indicating what would have been obvious to someone with ordinary skill at the time of the invention.

Additionally, the type of problems encountered in the field plays a significant role. A skilled person in the art would typically be familiar with the challenges and technical problems that arise within that domain. Understanding these issues allows for a better assessment of what would have been within the reach of ordinary skill.
