I don't know of any studies, but there is an interesting anecdote at  While
aviation provides a striking example, it is not isolated.  It seems
that in several areas of technology progress was impeded by patents
until companies formally or informally called a patent truce.

Many commentators have noted that software is (notable exceptions
notwithstanding) mostly in a truce of this form.  Googling about this
topic I ran across references to people in biotech wishing that they
had a patent pool because they are hitting this issue.
