3:12-cv-00355
Apple Inc v. Motorola Mobility Inc
I. Executive Summary and Procedural Information
- Parties & Counsel:
- Plaintiff: Apple Inc. and Apple Sales International (California and Ireland)
- Defendant: Motorola Mobility LLC (Delaware)
- Plaintiff’s Counsel: Covington & Burling LLP
- Case Identification: 3:12-cv-00355, S.D. Cal., 08/03/2012
- Venue Allegations: The complaint's specific allegations for venue in the Southern District of California have been redacted.
- Core Dispute: Plaintiff seeks declaratory judgment that it is shielded from patent infringement claims by Defendant concerning cellular standards-essential patents, based on its status as a third-party beneficiary to a license agreement between Defendant and Plaintiff's chip supplier, Qualcomm.
- Technical Context: The dispute centers on patents related to foundational methods for managing data transmission and radio resources in packet-based cellular communication standards, such as GPRS.
- Key Procedural History: The complaint alleges that Defendant Motorola declared its patents, including U.S. Patent 6,359,898, as essential to the GPRS cellular standard, committing to license them on Fair, Reasonable, and Non-Discriminatory (FRAND) terms. The action follows extensive litigation between the parties in Germany over the European equivalent patent and in U.S. district courts, where Defendant has asserted infringement against Apple products. This case seeks to establish that a pre-existing license between Motorola and Qualcomm, the supplier of baseband processors for Apple's products, exhausts Motorola's patent rights and prevents it from suing Apple.

II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 6,359,898 - Method for performing a countdown function during a mobile-originated transfer for a packet radio system
Issued 03/19/2002 (’898 Patent)
The Invention Explained
- Problem Addressed: In packet-based mobile communication systems, a network allocates radio resources (like time slots) to a mobile device for the duration of a data transmission. The patent’s background section notes that due to channel and processing delays, the network often does not learn that a device has sent its final data packet until several "block frames" later. During this delay, the network continues to allocate valuable resources to a device that no longer needs them, resulting in wasted system bandwidth and reduced capacity (’898 Patent, col. 1:28-46).
- The Patented Solution: The invention proposes a method for the mobile device to provide an earlier warning that its transmission is nearing completion. Instead of simply counting down the last few data blocks, the device calculates a "Countdown Value" (CV). This CV is an estimate of the number of remaining transmission frames (groups of time slots), not just individual data blocks. It is calculated by dividing the total number of remaining data blocks by the number of time slots currently allocated to the device. This CV is then inserted into the header of data blocks and transmitted, allowing the network to anticipate the transmission's end much sooner and reassign resources more efficiently (’898 Patent, col. 2:3-15, 31-34).
- Technical Importance: This method for predictive resource de-allocation was designed to increase the overall efficiency and capacity of packet radio networks by minimizing the waste of shared radio spectrum (’898 Patent, col. 1:41-46).
Key Claims at a Glance
- The complaint does not identify specific claims, as it seeks a broad declaration of non-liability. Independent claim 1 is representative of the mobile device-side method.
- Independent Claim 1 Elements:
- transmitting the plurality of units of information via a predetermined number of channel resources;
- determining a number of the plurality of units remaining in at least a portion of the communication signal;
- based on the predetermined number of channel resources, adjusting the number of the plurality of units remaining to produce an adjusted number of units remaining; and
- transmitting the adjusted number of units remaining to the wireless communication system.
III. The Accused Instrumentality
Product Identification
The complaint identifies Apple's iPhone 4S and "new iPad" products that incorporate Qualcomm's MDM6610 baseband processor (Compl. ¶22, ¶41).
Functionality and Market Context
- The MDM6610 baseband processor is a component that enables the iPhone 4S and other Apple devices to connect to and communicate over cellular networks (Compl. ¶23).
- The complaint alleges that infringement is based on the devices being compliant with the GPRS (General Packet Radio Service) cellular standard, issued by the European Telecommunications Standards Institute (ETSI) (Compl. ¶41). Motorola has allegedly declared the ’898 Patent as essential to practicing the GPRS standard, meaning compliance with the standard purportedly necessitates use of the patented technology (Compl. ¶26, ¶36). No probative visual evidence provided in complaint.
IV. Analysis of Infringement Allegations
The complaint, a declaratory judgment action, does not contain a formal claim chart. Instead, it describes Motorola's theory of infringement, which is based on the ’898 Patent's alleged status as a standard-essential patent (SEP) for the GPRS standard. The core of Motorola's alleged position is that because the Apple iPhone 4S uses a Qualcomm MDM6610 chip that is compliant with the GPRS standard, the device necessarily infringes the ’898 Patent (Compl. ¶36, ¶41).
'898 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| transmitting the plurality of units of information via a predetermined number of channel resources; | The iPhone 4S, via the MDM6610 chip, transmits packet data over a cellular network using one or more allocated channel resources (time slots) as specified by the GPRS standard. | ¶23, ¶41 | col. 1:19-21 |
| determining a number of the plurality of units remaining in at least a portion of the communication signal; | The device's software determines the number of remaining Radio Link Control (RLC) data blocks that have yet to be transmitted for a given data packet. | ¶41 | col. 2:3-5 |
| based on the predetermined number of channel resources, adjusting the number of the plurality of units remaining to produce an adjusted number of units remaining; and | To comply with the GPRS standard, the device's software adjusts the remaining block count by dividing it by the number of allocated time slots to generate a "Countdown Value" (CV). | ¶41 | col. 2:4-7 |
| transmitting the adjusted number of units remaining to the wireless communication system. | The device inserts the calculated CV into the header of the RLC data blocks and transmits them to the network, as required for GPRS-compliant communication. | ¶41 | col. 2:31-34 |
Identified Points of Contention
- Legal Question (License/Exhaustion): The central dispute is not over the technical operation of the iPhone, but whether Motorola's patent rights were exhausted by the licensed sale of the Qualcomm MDM6610 chip. A primary question for the court is whether the Motorola-Qualcomm license agreement shields downstream customers like Apple from infringement liability (Compl. ¶57; Count Five).
- Legal Question (FRAND Obligations): A related question is whether Motorola's declaration of the patent as essential to the GPRS standard and its corresponding FRAND licensing commitment legally constrain its ability to sue and seek injunctions against standard implementers like Apple (Compl. ¶26, ¶30).
- Technical Question (Essentiality): Underlying the legal arguments is the question of whether the ’898 Patent is truly essential to the GPRS standard. The litigation may explore whether it is technically possible to create a GPRS-compliant device without practicing the specific steps recited in the patent's claims.
V. Key Claim Terms for Construction
- The Term: "adjusting"
- Context and Importance: This term in claim 1 ("adjusting the number of the plurality of units remaining") describes the core calculation step of the invention. The scope of this term will be critical to determining whether the specific method for generating a countdown value in the GPRS standard falls within the claim. Practitioners may focus on this term because the specification appears to disclose only one specific mathematical operation (division) for performing the "adjusting."
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: Dependent claim 2 recites that the step of adjusting comprises "dividing." The doctrine of claim differentiation may suggest that the term "adjusting" in independent claim 1 is broader than merely "dividing" and could encompass other mathematical modifications.
- Evidence for a Narrower Interpretation: The detailed description of the preferred embodiment explicitly and repeatedly defines the calculation as a division: "the CV is calculated by dividing the remaining block count by the number of time slots being utilized" (’898 Patent, col. 2:4-7). This may be used to argue that the claim scope is limited to the only embodiment disclosed.
VI. Analyst’s Conclusion: Key Questions for the Case
This case appears less likely to turn on a technical infringement analysis and more on significant legal questions at the intersection of contract law, patent exhaustion, and standards-essential patents. The central questions for the court are:
- A core issue will be one of contractual rights and patent exhaustion: Does the existing license agreement between Motorola and Qualcomm shield Apple, as a downstream purchaser of licensed Qualcomm chips, from infringement liability, either as a third-party beneficiary or under the doctrine of patent exhaustion?
- A key secondary issue will be the enforceability of FRAND commitments: To what extent do Motorola's prior commitments to license its standards-essential patents on FRAND terms prevent it from pursuing infringement litigation and seeking injunctive relief against a willing licensee and implementer of the standard?
- A potential underlying issue is one of factual essentiality: Is the ’898 patent, as a matter of technical evidence, actually essential to implementing the GPRS standard in the accused Apple products, or can compliance be achieved without infringing the patent's claims?
