.~ Modification of viruses (e.g., attenuation, etc.)
DEFINITION
Classification: 435/173.3
Modification of viruses (e.g., attenuation, etc.):
(under subclass 173.1) Processes in which viruses are modified utilizing electrical or wave energy.
SEE OR SEARCH THIS CLASS, SUBCLASS:
5, for subject matter of measuring and testing utilizing a virus or bacteriophage.
235.1+, for subject matter involving a virus or bacteriophage, particularly subclass 236 which involves other processes of inactivation or attenuation.
440+, for processes wherein the genetic material is altered.

250, Radiant Energy, particularly
492.1, for processes of irradiation of objects or materials. 424, Drug, Bio-Affecting, and Body Treating Compositions,
particularly
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; subclasses 199.1, 201.1, 202.1, and 204.1 for an immunologic composition containing a virus (e.g., vaccines, etc.); subclass 93.6 for compositions or products under the class definition which contain nongenetically modified whole, live viruses. The mere use of the word vaccine, etc., is insufficient for placement in Class 424.
