II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 10,681,109 - “Image Display System with Visual Server”
- Patent Identification: U.S. Patent No. 10,681,109, “Image Display System with Visual Server,” issued June 9, 2020.
The Invention Explained
- Problem Addressed: The patent describes the technical and economic problems of delivering high-end, 3D graphics to consumer devices. These problems include the high cost of incorporating powerful graphics hardware into each client device, the constant need for hardware and software upgrades, and the difficulty of running sophisticated software on devices with limited processing power, such as mobile phones or set-top boxes (’109 Patent, col. 3:5-16, 3:26-31).
- The Patented Solution: The invention proposes a client-server architecture where a remote "visual server" performs the computationally intensive tasks of running an application (e.g., a game) and rendering the graphics (’109 Patent, Abstract). The server then compresses the resulting image and transmits it over a network to a client device, which only needs to decompress and display the image. The client sends user inputs back to the server to control the application, creating an interactive experience without requiring powerful local hardware (’109 Patent, col. 5:29-48; Fig. 3).
- Technical Importance: This server-based approach aimed to decouple high-end graphics performance from the capabilities of the end-user's device, promising to make complex applications accessible on a wider range of hardware (’109 Patent, col. 9:44-46).
Key Claims at a Glance
- The complaint asserts independent claims 1, 8, and 13, along with various dependent claims (Compl. ¶45).
- Independent Claim 1 (Method):
- Running an interactive software application at a server;
- Receiving user input signals from a client device at the server to control the application;
- Generating an updated image at the server in response to the inputs; and
- Compressing the image and transmitting it to the client device as a compressed frame for decompression and display.
- Independent Claim 8 (System):
- A server with a processor and memory configured to execute an interactive software application;
- The server is further configured to: receive user input signals from a client; generate an updated image in response; and compress and transmit the image as a frame;
- The client device is configured to decompress and display the updated image.
- The complaint reserves the right to assert dependent claims 2-4 and 6-7, as well as claims 9-12 and 14-18 (Compl. ¶45).
III. The Accused Instrumentality
Product Identification
- The accused instrumentalities are (i) the PlayStation Now cloud gaming service, (ii) the Remote Play feature, and (iii) the Share Play feature, as implemented on PlayStation 4 and 5 consoles and compatible client devices (Compl. ¶13).
Functionality and Market Context
- PlayStation Now: A subscription service where Sony hosts and runs PlayStation games on its own remote servers ("datacenters at strategic locations") and streams the compressed video output to a subscriber's client device, such as a PC or PlayStation console (Compl. ¶37, ¶39). Users provide input via a controller connected to their client device, which is sent back to the Sony server (Compl. ¶39).
- Remote Play & Share Play: These features use a local PlayStation console (PS4 or PS5) to function as a server, running a game and streaming its output to a remote client device over a local network or the internet (Compl. ¶40, ¶64). The client device can be a PC, Mac, mobile device, or another PlayStation console (Compl. ¶64). This allows a user to play their console games on another screen or, with Share Play, allow a friend to watch or take control of the game remotely (Compl. ¶17, ¶40). The complaint alleges that these services are based on technology acquired from Gaikai (Compl. ¶41).
IV. Analysis of Infringement Allegations
The complaint separates its infringement allegations, first mapping PlayStation Now to the claims and then mapping the Remote Play and Share Play features.
’109 Patent Infringement Allegations (PlayStation Now)
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| A method of hosting an interactive software application comprising: running at a server the interactive software application; | Sony’s PlayStation Now service operates by running interactive game applications on the PlayStation Now servers (Compl. ¶46.b.i). | ¶46.b.i | col. 9:56-58 |
| receiving at the server user input signals from a client device, wherein the user input signals are used to control updating of the state of the interactive software application; | The PlayStation Now server receives user input signals, such as DUALSHOCK 4 controller inputs, from the client device (e.g., a PC or PS4 console) to control the game (Compl. ¶46.c.i). | ¶46.c.i | col. 10:11-14 |
| generating at least one updated image at the server in response to updating the state of the interactive software application; and | In response to the user inputs, the game running on the server updates its state (e.g., changing the view angle) and generates updated images (Compl. ¶46.d.i). | ¶46.d.i | col. 10:21-25 |
| compressing the at least one updated image and transmitting the compressed updated image to the client device... as a compressed frame that can be decompressed and displayed... | The server compresses the generated image and transmits it as a compressed frame to the client device (PC or PS4), which then decompress and displays it. The complaint cites Sony’s marketing that games are "streamed from our servers... just like streaming a movie" (Compl. ¶18.i, ¶46.e.i). | ¶46.e.i | col. 10:65-col. 11:1 |
- Identified Points of Contention:
- Technical Questions: The complaint alleges that Sony's services operate as claimed, often citing marketing materials or a separate Sony-owned patent (the "Gaikai Patent") as evidence (Compl. ¶46.c.ii). A central evidentiary question may be whether the internal technical operation of the PlayStation Now servers, particularly the compression and data handling, matches the specific steps required by the patent's claims and described in its specification.
’109 Patent Infringement Allegations (Remote Play / Share Play)
| Claim Element (from Independent Claim 8) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| A server having a processor and memory configured to execute an interactive software application... | The PS4 console acts as the server, executing the PlayStation game application (Compl. ¶65.b.i, ¶67). | ¶67.b | col. 8:31-34 |
| Receiving at the server user input signals from a client device... | The PS4 console (acting as the server) receives user input signals, such as from a DUALSHOCK 4 controller, from a remote client device (e.g., a PC, Mac, or mobile device) (Compl. ¶65.c.i). | ¶67.c | col. 8:35-39 |
| Generating at least one updated image at the server in response to updating the state of the interactive software application... | In response to the user inputs, the PS4 console updates the game's state and generates new images (Compl. ¶65.d.i). | ¶67.d | col. 8:40-44 |

The complaint alleges these features stream games as compressed images (Compl. ¶65.e.i). | ¶67.e | col. 8:45-51 |
No probative visual evidence provided in complaint.
- Identified Points of Contention:
- Scope Questions: A primary question for claim construction may be whether a user's personal PlayStation console, when streaming to another of the user's devices (as in Remote Play), qualifies as "a server" within the meaning of the patent. The defense may argue the patent's context, which focuses on solving problems of client-side hardware cost and centralized maintenance (Compl. ¶33; ’109 Patent, col. 3:5-16), implies a commercial, multi-tenant server architecture rather than a peer-to-peer-like local stream.
- Scope Questions: The patent emphasizes enabling devices "lacking necessary hardware" or "unable to execute that software" ('109 Patent, col. 9:40-46). A question may arise as to whether clients like PCs or other PlayStation consoles, which are themselves powerful computing devices, fall within the intended scope of a "client device" as contemplated by the patent.
V. Key Claim Terms for Construction
- The Term: "server" (Claim 1, 8)
- Context and Importance: The definition of "server" is critical because the accused instrumentalities include both large-scale, remote data centers (PlayStation Now) and individual consumer game consoles (Remote Play/Share Play). The viability of the infringement case against the Remote Play and Share Play features hinges on whether a user's own PS4/PS5 console can be defined as "a server" under the patent.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The claims use the general term "a server" without further qualification. The specification describes the server's function as receiving data from a client, processing it, and sending back a modified image, a functional definition that a PS4 console arguably meets in Remote Play mode (’109 Patent, col. 4:50-57).
- Evidence for a Narrower Interpretation: The "Summary of the Invention" and "Background" sections frame the invention as a solution to problems associated with client-side hardware costs and the need for centralized upgrades, describing a "remote visual server" that hosts "standard software" for multiple clients (’109 Patent, col. 3:5-16, 4:37-43). This context may suggest the term "server" is limited to a centralized, commercially-managed system, not a consumer's personal device.
VI. Other Allegations
- Indirect Infringement: The complaint alleges Sony induces infringement by instructing customers, via marketing and user guides, on how to use the infringing features of Remote Play and Share Play. It further alleges Sony induces its business partners to develop games that support these features (Compl. ¶74).
- Willful Infringement: The willfulness claim is based on alleged pre-suit knowledge. Plaintiff alleges that Sony knew of the patent application due to prior litigation over related patents, that it monitored the prosecution, and that it was specifically alerted to the application in discovery exchanges (Compl. ¶78-80). The complaint further alleges Sony knew it had "no viable non-infringement defenses" because the '109 patent's claims lack limitations Sony allegedly relied on in the prior case (Compl. ¶82).
VII. Analyst’s Conclusion: Key Questions for the Case
This dispute centers on early-2000s priority patents for what is now a mainstream technology. The outcome may turn on a few key questions for the court:
- A core issue will be one of definitional scope: can the term "server," as used in a patent focused on solving problems of client hardware cost and centralized maintenance, be construed to cover a consumer's own gaming console when it streams content to another of their personal devices?
- A second key question will be one of infringement and claim scope: does the infringement theory against powerful client devices (like a PC or another console) conflict with the patent’s description of an invention intended to serve clients "lacking necessary hardware" or "unable to execute" the software locally?
- An evidentiary question will be one of technical proof: beyond marketing materials and analogies to other patents, what evidence will demonstrate that the precise, step-by-step technical operations of Sony’s complex streaming architecture meet the specific limitations recited in the asserted claims?
