Difference between class scope and object scope design patterns

Apparently design patterns have a ton of classifications. One I am struggling with is whether or not the pattern is a class scoped pattern or an object scoped pattern. Of course no documentation exists on the differences between the two, so I'm asking your opinion.

The GoF book defines it as:

"Class patterns deal with relationships between classes and their subclasses. These relationships are established through inheritance, so they are static-fixed at compile-time. Object patterns deal with object relationships, which can be changed at run-time and are more dynamic. Almost all patterns use inheritance to some extent. So the only patterns labelled "class patterns" are those that focus on class relationships. Note that most patterns are in the object scope."

Problem is, there are only class relationships as an object is nothing without its class. I've never heard of "object relationships" outside of this book.
