What role do structural similarities play in determining obviousness of species claims?
Structural similarities between the prior art genus or species and the claimed species play a significant role in obviousness determinations. As stated in MPEP 2144.08: “If such a prior art species or subgenus is structurally similar to that claimed, its disclosure may provide a reason for one of ordinary skill in the art to choose…
Read MoreHow do teachings of similar properties or uses affect obviousness determinations?
Teachings of similar properties or uses between the prior art and the claimed invention can significantly impact obviousness determinations. According to MPEP 2144.08: “Consider the properties and utilities of the structurally similar prior art species or subgenus. It is the properties and utilities that provide real world motivation for a person of ordinary skill to…
Read MoreHow does the size of a prior art genus affect obviousness analysis?
The size of a prior art genus is a factor to consider in obviousness analysis, but it’s not determinative on its own. As stated in MPEP 2144.08: “Consider the size of the prior art genus, bearing in mind that size alone cannot support an obviousness rejection. There is no absolute correlation between the size of…
Read MoreHow does the predictability of the technology affect obviousness analysis for species claims?
The predictability of the technology is an important factor in obviousness analysis for species claims. As stated in MPEP 2144.08: “Consider the predictability of the technology. If the technology is unpredictable, it is less likely that structurally similar species will render a claimed species obvious because it may not be reasonable to infer that they…
Read MoreWhat is the key consideration when analyzing obviousness of species claims?
The key consideration is whether the claimed species or subgenus would have been obvious to one of ordinary skill in the pertinent art at the relevant time. As stated in MPEP 2144.08: “The patentability of a claim to a specific compound, species, or subgenus embraced by a prior art genus should be analyzed no differently…
