In addition to granting Apple the summary judgment for the one patent, Koh also invalidated U.S. Patent No. 7,577,757. This belonged to Samsung and covered the syncing of content across multiple devices. Samsung acquired the patent in 2011 just for the express purpose of using it to take Apple to court.
The first patent suit between the the two firms resulted in a jury award of $1.05 billion for Apple. After noticing some inconsistencies between the amount the jury awarded Apple on some patents, Koh vacated $450 million of the judgment, and a damages retrial was held. Apple was awarded $290 million after seeking $380 million.
