II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 9,608,472 - METHOD AND APPARATUS FOR WIRELESSLY TRANSFERRING POWER AND COMMUNICATING WITH ONE OR MORE SLAVE DEVICES
- Patent Identification: U.S. Patent No. 9,608,472, METHOD AND APPARATUS FOR WIRELESSLY TRANSFERRING POWER AND COMMUNICATING WITH ONE OR MORE SLAVE DEVICES, issued March 28, 2017.
The Invention Explained
- Problem Addressed: The patent describes the limitations of conventional wireless power technologies, such as the very short distances required for magnetic induction and the potential for human exposure to non-directional energy fields ('472 Patent, col. 1:25-41). It also notes that existing high-frequency wireless communication standards (e.g., WirelessHD, WiGig) generally assume that a device already has a power source and do not address methods for charging the device first ('472 Patent, col. 3:9-12).
- The Patented Solution: The invention proposes a master-slave system where a "master" device authenticates a "slave" device before wirelessly transferring power ('472 Patent, col. 4:1-9). This power transfer, which can be accomplished via radio frequency (RF) beams or induction, can power up a device that has no battery or charge the battery of a device with limited power, often as a necessary step before communication can occur ('472 Patent, Abstract; col. 3:12-18).
- Technical Importance: This approach seeks to create a more integrated and secure wireless ecosystem where power and data transfer are managed together, allowing devices to be powered on-demand by an authorized source. ('472 Patent, col. 2:1-3).
Key Claims at a Glance
- The complaint primarily asserts independent method claim 19.
- The essential elements of claim 19 are:
- transmitting a slave device identification to the master device for determining authorization to wirelessly receive energy from the master device;
- wirelessly receiving, in response to transmitting the slave device identification to the master device, energy from the master device; and
- generating power from the wireless energy received from the master device for use by a set of electronic circuitry of the slave device.
- The complaint reserves the right to assert additional claims. (Compl. ¶14).
III. The Accused Instrumentality
Product Identification
- The "Naztech Ultimate Charging Station Pro" (the "Accused Product"). (Compl. ¶11).
Functionality and Market Context
- The Accused Product is a charging station that provides Qi-standard wireless charging, multiple USB ports, and includes a portable battery. (Compl. ¶¶11-12). A photograph provided in the complaint shows the charging station with a top surface for wireless charging and several front-facing USB ports. (Compl. p. 3, Figure). The complaint alleges that the Accused Product, when used with a Qi-compatible device (e.g., a smartphone), functions as a "master device" that engages in an identification and verification protocol with the "slave device" before transferring power, in accordance with the Qi standard. (Compl. ¶18).
IV. Analysis of Infringement Allegations
The complaint alleges infringement of method claim 19, asserting that the Accused Product (the master device) and a compatible Qi device (the slave device) together perform the claimed steps. The complaint references an "Exemplary Infringement Chart" (Exhibit 2) which was not attached to the filing; the analysis below is based on the narrative infringement theory provided in the body of the complaint. (Compl. ¶¶16, 18).
’472 Patent Infringement Allegations
| Claim Element (from Independent Claim 19) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| transmitting a slave device identification to the master device for determining authorization to wirelessly receive energy from the master device | The device to be charged (power receiver) sends an identification to the Accused Product (power transmitter) for identification and verification. | ¶18 | col. 36:25-30 |
| wirelessly receiving, in response to transmitting the slave device identification to the master device, energy from the master device | The Accused Product transfers power after successful verification, and the device to be charged receives that energy. | ¶18 | col. 36:31-34 |
| and generating power from the wireless energy received from the master device for use by a set of electronic circuitry of the slave device | The device to be charged generates power from the wirelessly received energy for use by its electronic circuitry. | ¶18 | col. 36:35-39 |
Identified Points of Contention
- Scope Questions: A primary question may be whether the patent’s claims, which are described in a specification that heavily emphasizes high-frequency, directional RF beams as an improvement over the prior art, can be construed to cover the Accused Product's use of the Qi standard, which is based on low-frequency, non-directional magnetic induction. The patentee may argue the term "energy" is broad, while the defendant may argue the specification limits the claim scope to the RF-based systems described as the invention.
- Technical Questions: The infringement analysis raises the question of whether the standard communication protocol of the Qi standard is equivalent to the claimed function of "determining authorization." The patent describes authorization as a way to prevent non-authorized masters from charging a device, potentially involving checking against a database. (Compl. ¶18; '472 Patent, col. 12:4-39). The court may need to consider whether the Qi "identification and verification" handshake performs this specific claimed function.
V. Key Claim Terms for Construction
The Term: "for determining authorization"
- Context and Importance: This term is central because it defines the purpose of the initial communication from the slave device. The case may turn on whether the Qi standard's technical handshake protocol, which the complaint alleges is used by the Accused Product, satisfies this functional requirement. Practitioners may focus on this term to distinguish between a simple technical prerequisite for power transfer and a more substantive security or permission-based check.
Intrinsic Evidence for Interpretation
- Evidence for a Broader Interpretation: The plain meaning of "authorize" could be interpreted broadly to mean "to permit" or "to enable." Under this view, any system where the master device verifies a slave's signal before transferring power could be seen as performing an authorization step.
- Evidence for a Narrower Interpretation: The specification describes a system where a slave device "prevents non-authorized masters (or networked servers) from trying to charge it or power it up by checking the master's identifying information with the authorized master's list stored on the slave." ('472 Patent, col. 4:1-6). This suggests "authorization" is a security feature to control which masters can provide power, a potentially more specific function than the standard interoperability handshake of the Qi protocol.
VI. Other Allegations
Indirect Infringement
- The complaint alleges induced infringement under 35 U.S.C. § 271(b), asserting that Defendant actively encourages its customers to infringe claim 19 by providing the Accused Product along with "downloadable instructional guides to enable and facilitate infringement." (Compl. ¶¶21, 23).
Willful Infringement
- The complaint alleges willfulness based on both pre-suit and post-suit conduct. It claims Defendant had knowledge "since at least the filing of this complaint" and also that Defendant acted "while knowing of, or being willfully blind to the existence of the '472 Patent." (Compl. ¶¶22-23). The prayer for relief seeks enhanced damages for this alleged willful infringement. (Compl. ¶B, p. 6).
VII. Analyst’s Conclusion: Key Questions for the Case
The resolution of this case will likely depend on the court's interpretation of the patent's scope and the specific function of the accused system. The central questions appear to be:
- A core issue will be one of technological scope: Can the claims of the '472 Patent, which the specification repeatedly frames as an improvement using high-frequency RF technology, be construed to cover the Accused Product's use of conventional, low-frequency magnetic induction as implemented in the Qi standard?
- A key question of claim construction will be one of functional meaning: Does the term "for determining authorization" require a security-based check against a list of approved devices, as described in embodiments in the patent, or is it broad enough to cover the standard technical "identification and verification" handshake of the accused Qi charging protocol?
