As Petitioner and its expert explain, a person of ordinary skill in the art would have been motivated to modify Figure 5 of Alie into a BSI device because BSI devices allow more incident light to reach the semiconductor layer, resulting in more light being absorbed, an increase in the quantum efficiency, and an improvement in the signal to noise ratio.

These factors are: 1. whether the court granted a stay or evidence exists that one may be granted if a proceeding is instituted; 2. proximity of the court’s trial date to the Board’s projected statutory deadline for a final written decision; 3. investment in the parallel proceeding by the court and the parties; 4. overlap between issues raised in the petition and in the parallel proceeding; 5. whether the petitioner and the defendant in the parallel proceeding are the same party; and 6. other circumstances that impact the Board’s exercise of discretion, including the merits.
