How do genus and species claims interact in interference proceedings?

In interference proceedings, the interaction between genus and species claims can be complex. The MPEP 2301.03 provides several examples to illustrate this interaction:

1. When one party claims a genus and another claims a species within that genus, the species claim would typically anticipate the genus claim, but the genus claim would not anticipate the species claim without additional explanation.
2. In cases where one party has both genus and species claims, multiple counts might be declared in the interference – one for the genus and one for the species.

For instance, the MPEP states:

“The species claim would correspond to the species count because the count would have anticipated the claimed subject matter. The genus count would not ordinarily have anticipated the species claim, however, so the species claim would only correspond to the genus count if there was a showing that the genus count would have rendered the claimed species obvious.”

This demonstrates that the relationship between genus and species claims in interference proceedings depends on the specific circumstances and requires careful analysis.
