During his tenure on the federal bench, Davis presided over 1,700 patent cases[8] and more than 250 Markman hearings (or claim construction hearings).[9]
Among the significant patent decisions Davis ruled on during his tenure on the bench included the case of i4i v.

Apple, the jury rendered a $368 million verdict which was later overturned on appeal to the Federal Circuit.[8] In the Eolas v.
