OPINION
We must decide whether the owners of mobile multimedia messaging networks can be held hable for copyright infringement that allegedly occurs on their networks.
I
Plaintiffs Luvdarts LLC and Davis-Reuss, Inc. (“Luvdarts”) are Califоrnia corporations that produce, publish, distribute and sell mobile multimedia content. AT & T Mobility, LLC and the other co-defendants are mobile wireless carriers (“Carriers”) who own Multimedia Messaging Service networks (“MMS networks”). Mobile phones use MMS networks to send and receive messages that include multimedia content.
Luvdarts alleges that it is in the business of selling commercial multimedia-messaging content designed to be transmitted over the MMS networks to and from mobile devices. According to its complaint, Luvdarts creates “greeting card style messages” as well as “MMS advertising campaigns, MMS news, MMS coupons, [and] MMS games.” Most of Luvdarts’s business involves selling these “greeting cards” to users who can then forward them to friends.
Attached to the content Luvdarts sells is a notice that it may be sharеd only once. But there is no technical impediment to a recipient forwarding a purchased message
Luvdarts sued the Carriers for copyright infringement. Thе First Amended Complaint alleges that the Carriers vicariously infringed, that they induced infringement, and that they violated California’s unfair competition laws. The Carriers filed a motion to dismiss the complаint for failure to state a claim on which relief can be granted. Fed.R.Civ.P. 12(b)(6). Luvdarts waived the state law claim, and the district court granted the motion as to the remaining infringement claims, dismissing the casе with prejudice.
II
Luvdarts’s principal argument is that the Carriers are liable for the infringement committed by third parties over their networks under either vicarious or contributory copyright liability. As the Suprеme Court has observed, the Copyright Act does not explicitly render a third person liable for another person’s infringement. Sony Corp. of Am. v. Universal City Studios,
A
Luvdarts first contends that the Carriers arе vicariously liable for infringement committed on their networks. Vicarious copyright liability is an “outgrowth” of respondeat superior. A & M Records, Inc. v. Napster Inc.,
Luvdarts fails to cite any authority to support this proposition, which runs contrary to our precedent. In Napster, this court held that “right and ability to supervise” should be еvaluated in the context of a system’s “current architecture.” Napster Inc.,
Even if the doctrine of vicarious liability imposed some affirmative duty to acquire supervisory capacity, Luvdarts has failed to allege facts that plausibly show that the Carriers could implement an effective system. Luvdarts’s complaint states only that the Carriers should “establish[ ] a me-tadata system of digital rights management.” Nowhere does Luvdarts explain what that system is, how it would function, or how much implementing such a system would cost. As a result, Luvdarts has not given us any facts that tend to make plausible the assertion that the Carriers could implement a system in the first place, much less that the Carriers could plausibly implement a system at a low-enough cost to justify imposition of vicarious liability.
Because Luvdarts has failed to allеge adequately that the Carriers had the necessary right and ability to supervise the infringing conduct, the district court properly determined that they cannot prevail on their claim of vicаrious copyright infringement.
B
Luvdarts’s second contention is that the Carriers are contributorily liable for the infringement committed on their networks. Liability for contributory copyright infringement attaches if thе Carriers (1) knew of the direct infringement; and (2) they either induced, caused, or materially contributed to the infringing conduct. See Napster,
To establish liability, the first prong requires more than a generalized knowledge by the Carriers of the possibility of infringement. It is undisputed that the Carriers engage in “the equivocal conduct of selling an item with substantial lawful as well as unlawful uses.” Grokster
Luvdarts fails to allege that the Carriers had the requisite specific knowledge of infringement. Luvdarts’s conclu-sory allegations that the Carriers had the required knowledge of infringement are plainly insufficient. See Ashcroft v. Iqbal,
In the alternative, Luvdarts argues that the “notices” it sent to the Carriers, referenced in the complaint, sufficed to establish actual knowledge of infringement. However, these notices failed to notify the Carriers of any meaningful fact.
Luvdarts also argues that the Carriers were “willfully blind” to the infringement that wаs occurring. Willful blindness of specific facts would establish knowledge for contributory liability. In re Aimster Copyright Litig.,
Because Luvdarts has failed to allege adequately that the Carriers had the necessary specific knowledge of infringement, it cаnnot prevail on its claim of contributory copyright infringement.
Ill
We conclude, in light of the foregoing, that Luvdarts has failed to state a claim on which relief could be granted. The district court thеrefore properly dismissed its complaint with prejudice.
AFFIRMED.
Notes
. Because Luvdarts has failed to allege adequately the first prong of vicarious liability, we have no cause to decidе whether the Carriers have a direct financial interest in the infringement.
. Because Luvdarts has failed to allege adequately the first prong of contributory liability, we have no cause to decide if Luvdarts has sufficiently alleged whether the Carriers induced or materially contributed to the infringement.
. We deny Luvdarts’s motions for judicial notice as moot.
