IBio Obtains European Patent Allowances For Protein Expression Technology

(RTTNews) - iBio Inc. (BIO) said that it received notices of intention to grant for two European patent applications claiming novel protein expression technologies.

The first newly allowed patent application entitled "Systems and Methods for Clonal Expression in Plants," includes claims to a system for generating transgenic hairy root cells containing a viral vector expressing a gene of interest. The system is used to generate a clonal root line, clonal root cell line, clonal plant cell line, or clonal plant having a self-replicating, episomal, extrachromosomal viral RNA vector that carries a polynucleotide of interest.

The second allowed patent application entitled "System for Expression of Genes in Plants," includes claims to methods for expressing one or more polynucleotides of interest using a set of plant viral vectors that function together. The polynucleotides of interest can include, for example, those encoding therapeutic proteins, one or more antibody chains, nutritionally relevant proteins, and polynucleotides that provide a template for transcription of an active RNA species.
