SUMMARY JUDGMENT ORDER

VINCE CHHABRIA, United States District Judge

I. Introduction

Unwired Planet has sued Apple for patent infringement. Unwiréd asserts claims from four different patents: U.S. Patent No. 6,317,831 ('831 patent), U.S. Patent No. 6,532,446 ('446 patent), U.S. Patent No. 6,646,260 ('260 patent), and U.S. Patent No. 6,321,092 ('092 patent). The parties have cross-moved for summary judgment on various issues.

Apple’s motion for summary judgment of noninfringement is granted with respect to the '831 patent, the '446 patent, and the '260 patent. This means several of the parties’ summary judgment arguments on those patent's are moot. Further, Apple has informed the Court that in the event the Court grants Apple’s motions for summary judgment of noninfringement, Apple will no longer pursue its invalidity counterclaims with respect to those patents at the upcoming trial, provided that it can still pursue them if the case is remanded on appeal. Therefore, the only remaining patent-in-suit will be the '092 patent.

And on the '092 patent, Apple’s motion for summary judgment of noninfringement is denied with respect to literal infringement, but is granted with respect to induced and contributory infringement. Unwired’s motion for summary judgment on Apple’s invalidity defense based on anticipatory prior art is granted. And both parties’ motions for summary judgment on Apple’s on-sale bar defense are denied.

II. '831 Patent

The '831 Patent describes a technique for more efficiently enabling secure data transactions using a narrowband channel. Each of the asserted claims— claims 17, 23, and 25 — requires a wideband channel to first exchange security informa[1088]*1088tion, and a narrowband channel to then transmit the relevant data over the secure connection. The primary difference between the two types of channels is the rate at which they transfer data. At claim construction, the' parties agreed to the Court’s proposed construction of narrow-band channel as “channel with a meaningfully lower data transfer rate or bandwidth than the wideband channel.”

Uriwired Planet alleges that the Apple Push Notification System (APNS) infringes the asserted claims of the '831 patent. APNS is an Apple feature that allows app providers to send push messages to an iOS device via APNS servers. Rather than connecting with multiple app provider servers, an iOS device need only connect to the APNS servers, because the app provider servers send messages to the APNS servers, which then send messages on to the iOS device. It is undisputed that APNS servers send push notifications to iOS devices using TCP/I? protocols, which are the standard communication protocols for transmitting data over the Internet.

When an APNS server sends a push notification to an iOS device, the message includes both a “payload” and a “header.” The payload is the portion of the message that contains the information to be presented to the user (if the push notification is from StubHub, for instance, the payload might say “Tickets for tonight’s Golden State Warriors game”). The header includes information related to accurate delivery of the message, such as the identity of the iOS device that should receive the message.

Apple contends that APNS does not meet the “narrowband channel” claim limitation as a matter of law. Unwired responds that the channel used to send push notification messages from the APNS servers to an iOS device is a narrowband channel, and it contends that APNS uses a wideband channel when APNS exchanges security information with an iOS device that later allows the APNS servers to send the push notification to the correct device.

As a threshold matter, to prevail on this infringement claim Unwired must be able to prove that APNS uses two separate channels, as required by the '831 patent. It’s debatable whether Unwired has provided sufficient evidence of this. There is no dispute that the exchange of both the security information (performed by the alleged wideband channel) and the push notification message (performed by the alleged narrowband channel) occur over a single Internet connection using TCP/IP protocols, which seems to belie the suggestion that they occur over different channels.

Unwired contends these APNS channels are different because they have different endpoints. Unwired’s expert, Dr. Mark Jones, claims the security information channel (alleged wideband channel) runs only from the iOS device to the APNS servers, whereas the push notification channel (alleged narrowband channel) extends back to the application provider servers. And he contends this makes them different channels. But as Apple correctly points out, “the asserted claims require both channels to connect to the same ‘server’ with the same ‘client,’ and Unwired contends that the ‘server’ is the APNS server and the ‘client’ is the iOS device.” Therefore, all that matters is the channel between the APNS servers and the iOS device; the communication that extends from the APNS servers to the application provider servers is not part of the accused system. And Unwired has given no real explanation (or evidence) of how the back- and-forth communication between the APNS servers and the iOS device occurs over different channels.

But even assuming for the sake of argument that APNS does use two separate [1089]*1089channels, these channels cannot be distinguished based on meaningfully different data transfer rates, which is the fundamental difference between a narrowband and wideband channel in the '831 patent. Dr. Jones asserts that push notification messages are sent at a lower data transfer rate than the security information, but his analysis is based on a faulty premise, and once this is recognized it becomes clear that there is no genuine issue of material fact.

Dr. Jones’ analysis is as follows: Apple limits the size of push notification messages to 256 bytes, a limitation that is not present when the APNS servers exchange security information with an iOS device. This size limitation results in a higher percentage of header information than is typically present in TCP/IP data transmissions. Further, header information should not be considered “data”; rather, only the payload — the portion of the push notification that includes the actual message to the user — should be considered data. Therefore, because the push notification contains significant overhead in the form of header information, and because header is not data, the payload (or data) reaches the iOS device at a slower rate than it otherwise would in a message with a lower percentage of header information, and thus the data transfer rate is meaningfully lower.1

At oral argument, counsel for Unwired analogized its infringement theory to coal trucks transporting coal from Point A to Point B. If the road between the two points only allows three coal trucks to travel at one time, and if each of those trucks includes a large engine that takes up space that could otherwise be filled with coal, then the overall amount of coal reaches Point B more slowly than if the road allowed ten trucks to travel at a time, or if the trucks had smaller engines and thus more space for coal. Accordingly, under this theory, the transfer rate of coal is meaningfully lower due to the overhead of the large engines and the restrictions on the number of trucks.

Rather than supporting Unwired’s infringement theory, this analogy shows why APNS does not infringe.
