DEFINITION

Classification: 435/235.1

VIRUS OR BACTERIOPHAGE, EXCEPT FOR VIRAL VECTOR OR BACTERIOPHAGE VECTOR; COMPOSITION THEREOF; PREPARATION OR PURIFICATION THEREOF; PRODUCTION OF VIRAL SUBUNITS; MEDIA FOR PROPAGATING:

(under the class definition) Subject matter excluding viral and bacteria-phage vectors, but including a virus or bacteriophage which is a microorganism that (a) consists of a protein shell around a nucleic acid core of either ribonucleic acid or deoxyribonucleic acid, and (b) is capable of independently entering a host microorganism, and (c) requires a host microorganism, having both ribonucleic acid and deoxyribonucleic acid, to replicate, compositions thereof under the class definition not elsewhere provided for, processes of preparation or propagation, media for propagating, processes of purifying the microorganism and processes of producing viral subunits.

(1) Note. Propagation is limited to processes concerned with the multiplication of viruses and not with processes concerned with the artificial alteration of genetic material involving changes in the genotype of the virus. Such processes of artificial alteration of genetic material are intended for this class, subclasses 440+.

(2) Note. This subclass provides for processes involving viruses of all types, i.e., animal, plant, etc.

SEE OR SEARCH THIS CLASS, SUBCLASS:

1, for process of maintaining tissue in a viable state or

media therefor.

2, for process of maintaining blood or sperm in a physiologically active state.

284+, for tissue or virus culture apparatus. 320.1, for vector, e.g., viral, phage, etc., where vector is intended to encompass a virus or phage which is used in the transformation or transfection of a cell. Transformation is the acquisition of new genetic material by incorporation of exogenous DNA and transfection is the transfer of genetic information to a cell using isolated DNA or RNA.

325+, for animal cells, per se, and culture processes therefore.

440+, for processes in which the genetic material of a microorganism is altered.

424, Drug, Bio-Affecting and Body Treating Compositions,

159.1+, for a process involving the step of immunizing an animal with a virus to produce a protective antiserum, followed by the step of obtaining the protective antiserum from the animal. See subclasses 199.1, 201.1, 202.1, and 204.1+ for an immunogenic composition that contains a virus, which composition induces protective immunity. Where there is doubt as to whether or not virus propagation takes place in preparing a vaccine, the process should be classified in Class 424 in the subclass providing for the corresponding viral vaccine. The mere use of the word vaccine is insufficient basis for placement in Class 424. See subclass 93.6, for compositions under the class definition containing a whole live virus.

930, Peptide or Protein Sequence,

220, 224 for sequence of peptides or protein homologous to a virus.

935, Cross-Reference Art Collection, Genetic Engineering: Recombinant DNA Technology, Hybrid or Fused Cell Technology, and Related Manipulations of Nucleic Acids,

25, and 32 for plant and animal virus vectors and subclass 31 for bacteriophage vectors.
