Marvell Semiconductor Inc. v. Monterey Research, LLC

Background

Monterey Research sued Marvell Semiconductor in the District of Delaware for patent infringement. Several months later, Marvell filed a similar action in the Northern District of California seeking declaratory relief. The parties disputed whether the California action should be dismissed or stayed while the Delaware court considered Marvell’s motion to dismiss or transfer the Delaware case to California.

Analysis

The court held that the first-to-file rule applied because of the sequence in which the two lawsuits were filed and their similarity. The court noted that Marvell argued venue was improper in the Delaware case, but said that was not immediately apparent. It also found that the California action did not need to remain on file to protect against a statute-of-limitations problem if the Delaware case were dismissed.

The court relied on the reasoning in a prior Northern District of California decision and concluded that dismissal without prejudice was warranted. Although the court said Marvell could not be blamed for filing the duplicative action because existing case law appeared to allow the practice, it criticized the practice as wasteful. The court stated that a party who believes venue is improper or that the first patent case should be transferred can file a motion in that case and await the ruling, rather than start a second lawsuit elsewhere.

Disposition

The order granted Monterey’s motion to dismiss. The court dismissed Marvell’s duplicative California action without prejudice. The opinion did not decide whether venue was proper in the Delaware case or whether that case should be dismissed or transferred.
