Fortunately, they have the “Fly over” population to keep things in a dextrorotatory lean.
Oil from the wild roots of North India is said to be highly levorotatory (rotates the plane of polarized light to the left), whereas that from the cultivated roots from South India is dextrorotatory (rotates polarized light to the right).
It was found chemically that cane sugar absorbs the elements of water and changes into a mixture of two different sugars, one being weakly dextrorotatory and the other strongly laevorotatory, hence the resultant is a rotation to the left.
The '265 patent discusses the unusual stereoselectivity of the biological properties as between the dextrorotatory and the levorotatory enantiomers.
This appeal is focused on the question of patentability of this dextrorotatory isomer in view of its known racemate described in earlier Sanofi patents, specifically, Sanofi's
In this case the district court said the references 'general statements that these compounds consist of enantiomers didn't make an anticipating disclosure of the separated dextrorotatory enantiomer of PCR 4099.
Clopidogrel is the common name of the dextrorotatory isomer of the chemical compound named methyl alpha-5 (4,5,6,7-tetrahydro (3,2-c) thienopyridyl) (2-chlorophenyl) - acetate.
Apotex argued that the recognition in the prior art that PCR 4099 is composed of enantiomers outweighs the effect of any unexpected or unpredictable properties of the separated dextrorotatory enantiomer.
The district court did not clearly err in finding that the statements in the '596 patent and its Canadian counterpart that the products therein consist of enantiomers are not a description of the specific dextrorotatory enantiomer clopidogrel or a suggestion of its unusual stereospecific properties.
As if that were not enough to ensure the longevity of refreshingly ordinary words like clockwise, further along the avenues of science we come across the adjectives dextrorotatory or dextrorotatary, dextrogyrous, dextrogyrate and dextrogyre.
