How does the level of ordinary skill in the art affect obviousness determinations?

How does the level of ordinary skill in the art affect obviousness determinations?

The level of ordinary skill in the art is a critical factor in obviousness determinations under 35 U.S.C. 103. According to MPEP 2141:

“The person of ordinary skill in the art is a hypothetical person who is presumed to have known the relevant art at the time of the invention.”

Key considerations regarding the level of ordinary skill include:

  • It affects how the prior art is interpreted and whether a combination of references would have been obvious
  • The hypothetical person is not an automaton, but possesses ordinary creativity
  • Factors that may be considered in determining the level of ordinary skill include:
    • Type of problems encountered in the art
    • Prior art solutions to those problems
    • Rapidity with which innovations are made
    • Sophistication of the technology
    • Educational level of active workers in the field

Examiners must consider the level of ordinary skill when assessing whether a claimed invention would have been obvious to a person having ordinary skill in the art at the time the invention was made. This assessment helps ensure that the obviousness determination is based on a realistic understanding of the knowledge and capabilities in the relevant field.
