Inside a plant, the herbicide glyphosate binds to a specific enzyme inside a plant chloroplast, known as EPSPS (enolpyruvylphosphoshikimate synthase enzyme), which then cannot carry out its typical crucial function in the biosynthesis of aromatic acids, and the plant dies. When the CaroA gene is expressed in transgenic plants, the bacterial EPSPS enzyme encoded by thiene fulfills the aromatic amino

The claim at challenge was directed to a nucleic acid sequence that encoded an EPSPS with two Ntermil chloroplast transit peptide sequences. The closest prior art taught exactly the same enzyme with only one particular Ntermil chloroplast transit sequence. Citing In re Dillon, DeKalb argued that the prior art publication alone rendered the claim obvious, asserting that “the structural variation among the two, i.e the second transit peptide, is an irrelevant variation, and consequently the claim is obvious.” The court stated that to draw the Dillon alogy, “DeKalb need to demonstrate that inside the relevant field of art, plant molecular biology, it was expected that constructs imparting glyphosate tolerance would have related properties with and without the need of a second transit peptide.” Two components went against DeKalb: DeKalb did not point to evidence that demonstrates any expectation within the relevant field of art with regards to the impact of a second transit peptide on glyphosate tolerance constructs (or any constructs); and substantial evidence was presented at trial demonstrating that the second transit peptide, far from being a “useless structural variation” as claimed by DeKalb, serves an important objective. The Synaptamide initial aspect demonstrates that in the time of invention, it was not known inside the art no matter if a second transit peptide would impact intracellular localization. For that reason, although the invention comprised the prior art sequence and only added an identical, second Ntermil targeting sequence, the invention was not apparent due to the fact there was a helpful effect in the second Ntermil targeting sequence that was not identified at the time of the invention. The second aspect demonstrates that even when DeKalb had succeeded in ^ producing a prima facie case, RhonePoulenc submitted adequate postfiling rebuttal proof that the second transit peptide did offer a functiol advantage more than the prior art. As a result, the claim was held to be nonobvious. In re Kubin A further exception in which an unknown, inherent feature can invalidate a claim limitation as apparent is when the limitation is claimed functiolly, as an alternative to structurally, and know-how in the functiol limitation is just not needed to combine references. In In re Kubin, the Federal Circuit decided a case of obviousness based in portion upon an inherent element that was claimed functiolly. The BPAI had found obvious claims drawn to D molecules encoding a protein called tural killer cell activationinducing ligand (IL).
