Mobilisable vectors – Patent Application filed by University of Leiden
Specific Patent Information
|Patent Number||Title, Independent Claims and Summary of Claims||Assignee|
|US 2003/87439 A1
||Title – Transformation of eukaryotic cells by mobilizable plasmids
The independent claims of the present patent application recite:
If the claims are granted as submitted, the resulting patent would provide protection for a broad spectrum of plasmids used for transformation via Agrobacterium. Binary and co-integrated vectors are based on the Ti-plasmid of Agrobacterium and the DNA transferred is always surrounded by T-DNA borders, while the plasmids of the present invention are derived from other bacterial sources, mainly bacteria from the family Enterobacteriaceae and do not use T-DNA borders for DNA transfer. Notice that the invention as filed is not limited to plants; all eukaryotic organisms may be encompassed by the claims in case of being granted as filed.
The structural and functional constraints on vir-like proteins are not disclosed- e.g., how much sequence difference/functional difference is tolerated for a protein to still be considered vir-like? The application merely repeats the claim language in the disclosure. The disclosure is also vague about the nature of gene products that would have activities “similar” to that of a functional virB operon though it indicates that homologues from other species are contemplated.
