II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 7,778,664 - “Communication Device”
- Issued: August 17, 2010
The Invention Explained
- Problem Addressed: The patent’s background section discusses a prior art mobile device with a display that could function as a pocket mirror by having a reflective surface, but notes this prior art does not disclose a device that uses its camera to create this mirror effect. (’664 Patent, col. 1:20-36).
- The Patented Solution: The invention is a multi-function communication device that implements a “digital mirror mode,” wherein an image captured by the device’s camera is displayed in an “inverted manner” on the screen, creating an intuitive mirror-like experience for the user. (’664 Patent, col. 1:45-48).
- Technical Importance: This approach of inverting or "mirroring" the image from a front-facing camera for on-screen previews became a standard feature in smartphones, commonly known as "selfie mode," as it provides a more natural user experience than a non-inverted image. (’664 Patent, col. 1:45-48).

IV. Analysis of Infringement Allegations
7,778,664 Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation | 
|---|---|---|---|
| A communication device comprising a microphone, a speaker, a display... a camera, an antenna, and a multiple mode implementor | The Accused Phones are wireless communication devices with microphones, speakers, displays, front and rear cameras, and antennas. | ¶17, 24, 25, 30, 38, 43 | col. 5:35-50 | 
| wherein said multiple mode implementor implements a voice communication mode, a digital mirror mode, a video phone mode, and a call blocking mode | The Accused Phones are capable of voice calls, audiovisual communication, displaying a mirror image via the front camera, and rejecting callers via "All calls to voicemail." | ¶17, 22, 23, 31, 44 | col. 1:45-48 | 
| visual data is input via said camera, said visual data is converted to an inverted visual data... and said inverted visual data is output from said display when said digital mirror mode is implemented | The Accused Phones' front camera is allegedly capable of displaying a "mirror image" of an object in its view. | ¶14, 16, 28, 44 | col. 1:47-48 | 
| when said communication device receives an incoming call... communication between the caller and said communication device is not implemented when said call blocking mode is implemented | The "All calls to voicemail" feature, when activated, allegedly prevents an incoming caller from conducting a voice communication. | ¶31, 32 | col. 7:45-50 | 
- Identified Points of Contention:- Scope Questions: The claim requires the device to implement a combination of four specific "modes" (voice communication, digital mirror, video phone, call blocking). A central question may be whether Plaintiff must prove every Accused Phone model implements all four distinct modes as claimed. For example, what evidence does the complaint provide that the "All calls to voicemail" feature constitutes the claimed "call blocking mode"?
- Technical Questions: Does the "mirror image" displayed by the Accused Phones (Compl. ¶44) result from a process that meets the claim limitation of converting visual data to "inverted visual data"? The analysis may hinge on the specific software and hardware implementation of the "selfie photo mirror" feature. (Compl. ¶16).
 
7,945,236 Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation | 
|---|---|---|---|
| A communication device comprising a... 1st camera, a 2nd camera... and a multiple function implementor | The Accused Phones are alleged to have a "front camera" and a second camera on the opposite side of the device. | ¶24, 26, 27 | col. 5:35-50 | 
| wherein said multiple function implementor implements a voice communication function, a digital mirror function, and a GPS function | The Accused Phones are alleged to be capable of voice communication, displaying a mirror image, and displaying their geographic location based on GPS data. | ¶17, 55, 56, 57 | col. 11:15-24 | 
| and the current geographic location of said communication device is indicated on said display when said GPS function is implemented | The Accused Phones are alleged to be capable of displaying their geographic location on their display, based at least in part on GPS data. | ¶33, 57 | col. 11:21-24 | 
- Identified Points of Contention:- Scope Questions: The claim requires a "GPS function" where the "current geographic location... is indicated on said display." Does any application that uses GPS to show location on a map (e.g., a third-party mapping app) satisfy this limitation, or must the functionality be a specific, integrated "mode" of the core operating system as contemplated by the patent?
- Technical Questions: The complaint states the phones are "capable" of displaying their location. (Compl. ¶57). An issue may be whether this capability alone is sufficient for infringement of the apparatus claim, or if specific software must be installed and configured to perform the claimed function.
 
V. Key Claim Terms for Construction
The Term: "digital mirror mode" (’664 Patent, Claim 1)
- Context and Importance: This term is the central novel feature of the ’664 Patent. Its construction will determine whether simply providing a "selfie" preview on a smartphone screen is infringing, or if a more specific technical implementation is required. Practitioners may focus on this term because the infringement allegation rests on equating the common "selfie photo mirror" feature with this claimed mode. (Compl. ¶16).
- Intrinsic Evidence for Interpretation:- Evidence for a Broader Interpretation: The claim language itself requires that "visual data is converted to an inverted visual data," which could arguably read on any software process that horizontally flips a camera feed for display. (’664 Patent, col. 33:8-12).
- Evidence for a Narrower Interpretation: The patent’s Summary of the Invention states the device "implements the digital mirror mode, wherein the image retrieved from the camera is displayed in an inverted manner." (’664 Patent, col. 1:45-48). The specification also distinguishes the invention from prior art that used a physical "reflecting" surface, suggesting the "mode" is an active software function, not a passive property. (’664 Patent, col. 1:20-36).
 
The Term: "GPS function" (’236 Patent, Claim 1)
- Context and Importance: The definition of this term is critical for determining the scope of the ’236 Patent. The dispute may turn on whether having a GPS receiver and the general capability to display location is sufficient, or if the claim requires a specific, integrated "function" that operates alongside the other claimed functions (voice, digital mirror).
- Intrinsic Evidence for Interpretation:- Evidence for a Broader Interpretation: The claim requires that the "current geographic location... is indicated on said display when said GPS function is implemented." This could be interpreted broadly to cover any standard use of a smartphone's GPS to show location on a map application. (’236 Patent, col. 33:2-4).
- Evidence for a Narrower Interpretation: The claim recites a "multiple function implementor" that implements a discrete set of functions. This suggests "GPS function" is not just a hardware capability but a specific software mode that is part of the claimed combination, potentially requiring a particular integration with the voice and digital mirror functions. (’236 Patent, col. 32:46-48).
 
VI. Other Allegations
- Indirect Infringement: For each asserted patent, the complaint alleges induced infringement under 35 U.S.C. § 271(b). The basis for these allegations is that Motorola provides "User guides, that instruct consumers on how to use the Accused Phones in such infringing manner, specifically intending such consumers will operate" the devices as claimed. (Compl. ¶48, 61, 74, 87, 100, 113, 128).
- Willful Infringement: The complaint does not contain an explicit allegation of willful infringement or plead facts supporting pre-suit knowledge of the patents. It alleges that Motorola has engaged in inducement "knowingly and, at least from the time of receipt of the Complaint," which may support a claim for post-filing inducement or willfulness. (Compl. ¶50, 63, 76, 89, 102, 115, 130).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of claim scope for system claims: The asserted independent claims each require a single device to implement a specific combination of multiple, distinct "modes" or "functions." A central question for the court will be whether infringement requires proving that every accused device practices every single claimed function (e.g., voice communication, digital mirror, video phone, and call blocking for the ’664 patent), or if the capability to perform these functions is sufficient.
- A key evidentiary question will be one of functional mapping: The complaint alleges infringement by mapping common, commercially-named smartphone features (e.g., "selfie photo mirror," "Moto Voice") to the technical "modes" recited in the claims. The case may turn on what evidence is presented to demonstrate that these features perform the specific technical operations required by the patent claims, particularly for terms like "inverted visual data" and "call blocking mode."
