  A Sleeping Beauty in Science is a publication that goes unnoticed (sleeps)
for a long time and then, almost suddenly, attracts a lot of attention (is
awakened by a prince). In our foregoing study we found that roughly half of the
Sleeping Beauties are application-oriented and thus are potential Sleeping
Innovations. In this paper we investigate a new topic: Sleeping Beauties that
are cited in patents. In this way we explore the existence of a dormitory of
inventions. We find that patent citation may occur before or after the
awakening and that the depth of the sleep, i.e., citation rate during the
sleeping period, is no predictor for later scientific or technological impact
of the Sleeping Beauty. Inventor-author self-citations occur only in a small
minority of the Sleeping Beauties that are cited in patents, but other types of
inventor-author links occur more frequently. We analyze whether they deal with
new topics by measuring the time-dependent evolution in the entire scientific
literature of the number of papers related to both the precisely defined topics
as well as the broader research theme of the Sleeping Beauty during and after
the sleeping time. We focus on the awakening by analyzing the first group of
papers that cites the Sleeping Beauty. Next, we create concept maps of the
topic-related and the citing papers for a time period immediately following the
awakening and for the most recent period. Finally, we make an extensive
assessment of the cited and citing relations of the Sleeping Beauty. We find
that tunable co-citation analysis is a powerful tool to discover the prince and
other important application-oriented work directly related to the Sleeping
Beauty, for instance papers written by authors who cite Sleeping Beauties in
both the patents of which they are the inventors, as well as in their
scientific papers.
