  • Plaintiff’s Counsel: Rabicoff Law LLC
• Case Identification: 6:22-cv-00348, W.D. Tex., 04/01/2022
• Venue Allegations: Plaintiff alleges venue is proper in the Western District of Texas because Defendant engages in systematic and continuous business activities, provides its products to residents, and has committed acts of patent infringement within the district.
• Core Dispute: Plaintiff alleges that Defendant’s wireless projectors infringe patents related to using a mobile communications device, such as a smartphone, to control and stream media content to a separate, external display device.
• Technical Context: The technology addresses the use of a mobile phone as a central control hub for a larger media experience, a departure from the prior art paradigm of phones as self-contained, standalone media players.
• Key Procedural History: The complaint notes that during prosecution of the parent '342 Patent, the inventor distinguished the claims from prior art "conventional tethering," arguing the invention reverses the traditional "client/server relationship" by having the mobile device control the peripheral. The complaint also states that the Patent Trial and Appeal Board (PTAB) declined to institute an Inter Partes Review (IPR) against the asserted claim 21 of the '342 Patent (IPR2016-00989), finding no reasonable likelihood of unpatentability on the grounds presented.

Case Timeline

II. Technology and Patent(s)-in-Suit Analysis

U.S. Patent No. 9,547,981 - System, Method and Apparatus for Using a Wireless Device to Control Other Devices, issued January 17, 2017 ('981 Patent)

The Invention Explained

• Problem Addressed: The patent describes a technical landscape where cell phones were evolving into multimedia devices, but their use was confined by small, low-resolution screens and keypads, creating ergonomic constraints (Compl. ¶10; ’981 Patent, col. 2:27-34). State-of-the-art devices were designed as standalone media players, not as controllers for external, higher-quality displays (Compl. ¶10).
• The Patented Solution: The invention proposes a method where a mobile communications device acts as a remote control and media conduit for a separate, superior display device (e.g., a high-definition monitor or television). The user interacts with a GUI on the external display to select content (e.g., a movie from a server), which is then downloaded to the mobile device and simultaneously transmitted to the external display for viewing, creating a "media center environment" controlled by the phone (Compl. ¶10; ’981 Patent, col. 3:1-31). This is illustrated in the patent's discussion of transmitting streaming media to a full-size display device ('981 Patent, col. 5:8-13).
• Technical Importance: This approach shifted the paradigm from the phone being the primary viewing device to the phone being the "brain" of a larger, more user-friendly media system (Compl. ¶10).

Key Claims at a Glance

• The complaint asserts independent claim 1 and dependent claims 5 and 15-16 (Compl. ¶28).
• Independent Claim 1 (Method):
  • Electrically coupling a display device with a mobile communications device for consumer electronic entertainment purposes.
  • Causing a first graphic user interface (GUI) to be displayed on the display device, which shows information about individually downloadable videos.
  • Receiving entertainment selection commands on the mobile device to select a video based on visual feedback from the GUI on the display device.
  • Receiving, by the mobile device, the selected video from the server.
  • Transmitting at least some of the video from the mobile device to the display device simultaneously while at least some of the video is being downloaded from the server to the mobile device.
  • Wherein the electrical coupling allows this transmission when the mobile device is located a distance away from the display device.

U.S. Patent No. 8,135,342 - System, Method and Apparatus for Using a Wireless Cell Phone Device to Create a Desktop Computer and Media Center, issued March 13, 2012 ('342 Patent)

The Invention Explained

• Problem Addressed: As with its continuation, the '981 Patent, the '342 Patent addresses the limitations of using a cell phone as a self-contained computing device and the failure of the prior art to "disengage" users from the "ergonomic constraints of the small, low-resolution displays" ('342 Patent, col. 2:18-24).
• The Patented Solution: The patent discloses a system that allows a wireless cell phone to function as a "thin client" or central processing and communications hub for a complete desktop or media center environment ('342 Patent, col. 2:27-40). This involves connecting the phone to peripheral devices like a full-size monitor, keyboard, and mouse, and using the phone's network connectivity to access browser-based applications and media, which are then employed by the peripherals under the user's control via the phone ('342 Patent, Abstract; Fig. 1).
• Technical Importance: The invention proposed a reversal of the "traditional client/server relationship," where the portable device controls the peripheral, rather than simply tethering to a more powerful computer (Compl. ¶¶12, 14).

Key Claims at a Glance

• The complaint asserts dependent claim 21 (Compl. ¶34).
• Dependent Claim 21 (System):
  • A peripheral device control system (from parent claim 20) further comprising:
  • Means for receiving, at the peripheral device, a wireless communication containing the downloaded user information from the wireless device.
  • Means for employing, at the peripheral device, the downloaded user information.

III. The Accused Instrumentality

Product Identification

• Defendant’s "Projector Infringing Products," which include the "Yaber WiFi Mini Projector v2" and other substantially similar products (Compl. ¶¶27, 29).

Functionality and Market Context

• The complaint alleges that the accused projectors contain "casting circuitry" that enables a user to perform screen mirroring or casting (Compl. ¶¶27, 28). The alleged mode of operation involves a user selecting a video (e.g., from YouTube) on a smartphone, which downloads the video from a server to the phone and then wirelessly casts it to the projector for display (Compl. ¶28). The complaint cites Defendant's marketing materials, which state the projector "supports WiFi connection for both iOS/Android devices" and can "mirror movies . . . from your smartphone or other Miracast enabled devices to big screen freely" (Compl. ¶29). The complaint references marketing language from Defendant's website describing the projector's ability to "mirror movies . . . from your smartphone or other Miracast enabled devices to big screen freely" (Compl. ¶29).

IV. Analysis of Infringement Allegations

'981 Patent Infringement Allegations

'342 Patent Infringement Allegations

Identified Points of Contention

• Technical Questions: A primary factual dispute for the ’981 Patent may concern the "simultaneously" limitation. The case may require evidence on whether the accused system streams data directly through the phone to the projector in real-time, or if it utilizes a store-and-forward mechanism where a significant portion of the video is buffered on the phone before transmission, potentially breaking the "simultaneous" link required by the claim.
• Scope Questions: For both patents, a question of scope is whether the combination of the projector and the wall or screen it projects onto constitutes the claimed "display device" or "peripheral device" within a "media center environment," as the patents describe a system for creating a "desktop computer" environment.
• Means-Plus-Function: The infringement analysis for the ’342 Patent will focus on its means-plus-function claims. A central question will be whether the accused projector's "casting circuitry" is structurally equivalent to the specific "peripheral communications hardware and software" and "device drivers" disclosed in the patent's specification (e.g., ’342 Patent, Fig. 1, items 480, 460) as the structures that perform the receiving and employing functions.

V. Key Claim Terms for Construction

• Term: "transmitting... simultaneously while at least some of the particular movie or video is being downloaded" ('981 Patent, Claim 1)

  • Context and Importance: This term is central to the method's streaming capability and was highlighted during prosecution to distinguish from prior art that required a full download before access (Compl. ¶13). Its construction will determine whether the accused product's buffering and casting process meets the claim.
  • Intrinsic Evidence for a Broader Interpretation: The patent's general references to "streaming video" and "streaming media" could support a view that any process commonly understood as streaming, which involves concurrent download and playback, falls within the scope, even with some buffering ('981 Patent, col. 5:11, col. 10:4-5).
  • Intrinsic Evidence for a Narrower Interpretation: The specific word "simultaneously" could be argued to require a strict, near-instantaneous temporal relationship between a bit being received by the phone and being transmitted from the phone, a standard that a system with significant buffering might not meet.

• Term: ""means for receiving"... a wireless communication" / ""means for employing"... said downloaded user information" ('342 Patent, Claim 21)

  • Context and Importance: As means-plus-function limitations, their scope is not limitless but is confined to the corresponding structures disclosed in the specification and their equivalents. The infringement determination will depend entirely on a structural comparison between the accused device and the patent's disclosed embodiments.
  • Intrinsic Evidence for Interpretation: The scope of these terms is defined by the structures disclosed in the patent to perform the recited functions. This includes the "peripheral communications hardware and software" (e.g., supporting USB, IEEE 1394, and IEEE 802.11 protocols) and "device drivers" ('342 Patent, col. 6:52-56; Fig. 1, items 480, 460). The dispute will be whether the accused projector’s general-purpose WiFi and "casting circuitry" is structurally equivalent to this disclosed hardware and software stack.

VI. Other Allegations

• Indirect Infringement: For both patents, the complaint alleges induced infringement. The factual basis is Defendant's alleged promotion of the infringing functionality on its website, which allegedly "actively induces its customers to use the device" in a manner that performs the claimed steps or forms the claimed system (Compl. ¶¶30, 36).
• Willful Infringement: The complaint does not allege pre-suit knowledge of the patents. It pleads that Defendant has had knowledge of the '981 and '342 patents "since at least the date when this complaint was filed" or "since the filing of the complaint" (Compl. ¶¶31, 37). This appears to limit the willfulness claim to post-filing conduct.

VII. Analyst’s Conclusion: Key Questions for the Case

• A central issue will be one of structural equivalence: for the '342 patent’s means-plus-function claims, is the accused projector's integrated "casting circuitry" legally equivalent to the more modular "peripheral communications hardware and software stack" disclosed in the specification as the structure for receiving and employing user information?
• A key evidentiary question will be one of technical operation: does the accused system’s method of casting content from a smartphone meet the '981 patent’s requirement of "simultaneously" transmitting video to the projector while it is being downloaded to the phone, or is there a functional mismatch in its buffering and data handling?
• The case will also likely involve a question of definitional scope: can the term "peripheral device," rooted in the patent's context of creating a "desktop computing environment," be construed to read on the accused projector, which is marketed as a consumer entertainment device for a "home media center environment"?
