Technically yes, but it is neither common nor advisable for most businesses. Registering in all 45 classes is very expensive, significantly increases the risk of opposition, and creates extensive non-use vulnerability; a trademark must be put to genuine use in each registered class within five years or become vulnerable to cancellation in the unused classes.

Well-known global brands sometimes hold registrations across many classes as a defensive strategy, but this is a resource-intensive approach suited to large enterprises with significant brand management infrastructure. For most businesses, registering in the classes that reflect actual commercial activity is the practical approach.
