The difference between software classified in Class 9 and in Class 42 is that Class 9 software is downloadable – i.e. storable and retrievable in and from one’s own system like when the software is on a CD, although nowadays it is simply downloaded from the internet, but it must remain in the computer hard drive (or an external memory device). Software in Class 42 is “nondownloadable” software, e.g. “software as a service” or application software generally only available for use when the user accesses a particular website but not stored in their own system retrievable at will. This nondownloadable software is considered to be like a computer service which is why it is classified in Class 42.
