772 F.3d 723
Fed. Cir.2014Background
- e.Digital appealed a district court judgment of non-infringement regarding the '774 and '108 patents after collateral estoppel rulings.
- Colorado court construction of the '774 sole memory limitation indicated RAM was not required where flash memory could be directly addressed.
- The USPTO cancelled claims 1 and 19 of the '774 patent after ex parte reexamination; reexamined claim 33 recited the same sole memory limitation but added a microprocessor.
- District court adopted the Colorado construction for the '774 sole memory limitation and extended collateral estoppel to the '108 patent due to relatedness.
- GoPro, Pantech, Huawei, and Apple cases were consolidated for discovery and construction; partial judgments were entered and converted under Rule 54(b).
- Opinion concludes collateral estoppel applies to the '774 patent but not to the unrelated '108 patent; Rule 54(b) conversion was not an abuse of discretion.
