I'd like to draw your attention to the recently published judgement from the 
High Court of Australia, in a case which most certainly involved how much 
copying is "substantial".
Many of the cases referenced are from the UK.

Substantial part

 
 So as to indicate that the time and title information alleged to have been 
reproduced did not form a large part of a Weekly Schedule, the primary judge 
referred to the copying of "slivers of information"[29]. However, in order to 
assess whether material copied is a substantial part of an original literary 
work, it is necessary to consider not only the extent of what is copied: the 
quality of what is copied is critical[30]. 
 
 This principle has a long provenance[31] and it is particularly apposite when 
considering a compilation. Some compilations are no more than a selection or 
arrangement of facts or information already in the public domain. When the 
particular form of expression contains facts and information, it is not 
helpful to refer to "the rough practical test that what is worth copying is 
prima facie worth protecting"[32]. To take an example, facts are obviously 
worth copying for purposes such as a narrative work of history which depends 
on secondary sources[33]. It is equally unhelpful to refer to the "commercial 
value" of the information, because that directs attention to the information 
itself rather than to the particular form of expression.
 
 It is often said that questions of whether a substantial part has been copied 
are questions of fact and degree[34]. However, a factor critical to the 
assessment of the quality of what is copied is the "originality" of the part 
which is copied[35].
