Case Timeline

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

U.S. Patent No. 10,346,105 - “Method and system for communicating between a remote printer and a server”

The Invention Explained

• Problem Addressed: The patent’s background section describes the conventional process of printing digital images from the internet as "cumbersome," "tedious, time-consuming, and error-prone," in part because it requires a host computer to download the image and issue a print command (’105 Patent, col. 2:16-17, col. 2:65-67). This requirement limits user mobility and the locations from which printing can occur (’105 Patent, col. 3:4-15).
• The Patented Solution: The invention provides a protocol for direct communication between a remote printer and a server. The printer establishes a network connection (a "socket"), authenticates itself with the server, requests and receives print data in portions, and notifies the server after printing is complete (’105 Patent, Abstract; FIG. 2). This system is designed to allow the printer to operate without a companion computer, connecting directly to a network like a POTS or wireless network to download and print data (’105 Patent, col. 4:46-53, col. 5:4-8).
• Technical Importance: This approach sought to decouple printers from dedicated host computers, a key step toward enabling network-aware peripheral devices and mobile printing applications.

Key Claims at a Glance

• The complaint asserts "one or more claims" without specifying them (Compl. ¶17). Independent claim 1 is representative of the server-side method.
• Essential Elements of Claim 1 (Method):
  • Receiving, by a computing device (server) from a remote printer, data identifying one or more characteristics of the printer.
  • Verifying that the remote printer has been registered with the computing device.
  • Sending to the remote printer an indication of a number of data items to be printed and a number of print data items to be downloaded.

U.S. Patent No. 7,383,321 - “Method and system for communicating between a remote printer and a server”

The Invention Explained

• Problem Addressed: The patent identifies the unreliability of data communications over telephone and wireless connections as a key technical challenge for remote printing systems (’321 Patent, col. 3:40-42). An interruption during a data transfer would typically require the process to restart from the beginning.
• The Patented Solution: The invention discloses a communication protocol that ensures reliable data transmission and allows a transfer to "restart at the point of interruption if interrupted" (’321 Patent, col. 3:45-47). The protocol involves the printer requesting data in portions and includes the use of "security indicators" (such as a Cyclic Redundancy Code, or CRC) transmitted with the data, which the printer can use to verify the integrity of the received data portion (’321 Patent, Abstract; col. 8:15-28). This robustness allows the system to function over potentially noisy or unstable network connections.
• Technical Importance: The focus on reliable, restartable downloads was critical for making early network-connected devices functional over consumer-grade connections like dial-up telephone lines.

Key Claims at a Glance

• The complaint asserts "one or more claims" without specifying them (Compl. ¶23). Independent claim 1 is representative of the printer-side method.
• Essential Elements of Claim 1 (Method):
  • Establishing an interprocess communication mechanism (e.g., a socket) with a server.
  • Sending an authentication request to the server.
  • Receiving an authentication response.
  • Requesting print data portions to be downloaded.
  • Attempting to receive the print data portions, which includes receiving a server-calculated security indicator, calculating a printer-side security indicator, and comparing them to verify data integrity.
  • Notifying the server after print completion.
  • Terminating the communication connection.

U.S. Patent No. 7,958,205 - “Method and system for communicating between a remote printer and a server”

Technology Synopsis

This patent, from the same family as the ’321 Patent, describes a protocol for enabling a remote printer to download and print data from a server without a host computer (’205 Patent, col. 4:35-39). It details the communication steps, including establishing a connection, authentication, requesting data portions, and notifying the server after printing, with a focus on creating a reliable connection over potentially unstable networks (’205 Patent, Abstract).

Asserted Claims

"one or more claims" (Compl. ¶32).

Accused Features

The "Exemplary Defendant Products" are alleged to practice the claimed technology (Compl. ¶32).

U.S. Patent No. 8,645,500 - “Method and system for communicating between a remote printer and a server”

Technology Synopsis

Continuing the technology of the parent patents, the ’500 Patent discloses a method for communication between a remote printer and a server. The protocol is designed to handle potentially unreliable network connections by allowing for partial downloads and verification, thereby enabling a printer to operate as a standalone, network-connected device (’500 Patent, Abstract; col. 4:46-53).

Asserted Claims

"one or more claims" (Compl. ¶38).

Accused Features

The "Exemplary Defendant Products" are alleged to practice the claimed technology (Compl. ¶38).

U.S. Patent No. 8,773,685 - “High-speed digital image printing system”

Technology Synopsis

This patent addresses a different problem: reducing the total time required for a commercial photo-printing kiosk to print multiple digital images (’685 Patent, col. 2:62-65). The proposed solution involves a client-server architecture within the kiosk, where images are transferred to a print server and stored in a high-speed RAMdisk before printing begins (’685 Patent, col. 4:29-33). The system can also preprocess images in an optimized order (e.g., most complex first) to ensure a continuous stream of data to the print engine, avoiding stop/start cycles (’685 Patent, col. 4:48-55).

Asserted Claims

"one or more claims" (Compl. ¶44).

Accused Features

The "Exemplary Defendant Products" are alleged to practice the claimed technology (Compl. ¶44).

U.S. Patent No. 9,448,750 - “Method and system for communicating between a remote printer and a server”

Technology Synopsis

This patent describes the server side of the remote printing communication protocol. The method involves the server receiving identifying characteristics from a printer, verifying that the printer is registered in a database, and then sending information about the print jobs available for download (’750 Patent, Claim 1). This allows the server to manage and serve content to authorized remote printing devices.

Asserted Claims

"one or more claims" (Compl. ¶53).

Accused Features

The "Exemplary Defendant Products" are alleged to practice the claimed technology (Compl. ¶53).

It covers the core steps of establishing a connection, authentication, requesting and receiving print data in portions, and notifying the server of print completion (’836 Patent, Abstract). The method is designed to provide robust and reliable printing for a network-connected printer that does not rely on a local host computer.

Asserted Claims

"one or more claims" (Compl. ¶59).

Accused Features

The "Exemplary Defendant Products" are alleged to practice the claimed technology (Compl. ¶59).

III. The Accused Instrumentality

Product Identification

• The complaint does not name any specific accused products in its main body. It refers to them as the "Exemplary Defendant Products" that are identified in claim chart exhibits incorporated by reference (Compl. ¶17, ¶23).

Functionality and Market Context

• The complaint does not provide sufficient detail for analysis of the accused products' functionality or market context, as this information is contained within external exhibits that were not provided with the complaint.

IV. Analysis of Infringement Allegations

The complaint alleges that Defendant’s products infringe the asserted patents but provides no specific factual allegations to support this claim in the body of the document. Instead, it incorporates by reference a series of claim chart exhibits (Exhibits 8-14) that allegedly compare the patent claims to the "Exemplary Defendant Products" (Compl. ¶19, ¶28, ¶34). As these exhibits were not provided, a detailed claim chart summary cannot be constructed. The complaint’s narrative theory is that Defendant’s products practice the technology claimed by the patents-in-suit, thereby satisfying all elements of the asserted claims (Compl. ¶19, ¶28).

No probative visual evidence provided in complaint.

• Identified Points of Contention:
  • Scope Questions: A primary question may be whether the term "remote printer," described in the patents in the context of consumer photo printing, can be construed to read on Defendant's industrial coding and marking systems. The applicability of the claimed client-server protocol to an industrial environment will likely be a central point of dispute.
  • Technical Questions: For the server-communication patents (e.g., ’105 and ’321), a key question will be evidentiary: what proof shows that Defendant's systems perform the specific claimed steps, such as sending printer characteristics for registration verification, requesting partial data downloads to resume interrupted transmissions, and sending post-print notifications to a server? For the ’685 Patent, the question will be whether Defendant’s systems utilize a RAMdisk-based queuing architecture specifically to optimize print engine throughput, as claimed.

V. Key Claim Terms for Construction

• The Term: "remote printer" (e.g., ’321 Patent, Claim 1)

• Context and Importance: The construction of this term may be dispositive. The patents’ specifications are grounded in the problem of printing digital photographs from the web, often from mobile or standalone consumer devices. Defendant, however, operates in the industrial printing and coding market. Practitioners may focus on this term because its scope will determine whether the patents are applicable to the accused technology at all.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The specification of the ’321 Patent states that the term "printer" is used herein to refer to any device for receiving input and producing hard or soft copy output," including devices producing audiovisual streams (’321 Patent, col. 4:51-58). This language could support a broad construction that is not limited to a specific type of device or market.
  • Evidence for a Narrower Interpretation: The "Related Art" and "Background" sections of the patents consistently frame the problem and solution in the context of consumer digital photography, the use of host PCs, and printing from the Web (’321 Patent, col. 1:39-col. 2:67). This context may be used to argue for a narrower definition limited to the field of the invention as described.

• The Term: "verifying . . . that the remote printer has been registered" (e.g., ’105 Patent, Claim 1)

• Context and Importance: This term is central to the claimed authentication process. The dispute will likely involve whether the accused systems perform an equivalent step and what technical actions satisfy the "verifying" requirement. A narrow construction could require a specific database look-up, while a broader one could cover any form of access control.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The claim language itself does not specify the mechanism for verification, which could support an interpretation covering any method by which a server confirms a printer is authorized.
  • Evidence for a Narrower Interpretation: The detailed description and figures of the ’105 Patent disclose a specific verification process where the server receives printer characteristics like serial and model numbers and compares them to a database to "verify registration" (’105 Patent, FIG. 8; col. 10:41-48). This explicit embodiment may be cited to argue for a more limited claim scope.

VI. Other Allegations

• Indirect Infringement: The complaint alleges induced infringement for the ’321 and ’685 Patents. The allegations are based on Defendant’s knowledge of the patents from at least the service of the complaint, and on the distribution of "product literature and website materials" that allegedly instruct users on how to operate the products in an infringing manner (Compl. ¶¶26-27, 47-48).
• Willful Infringement: While not pleaded as a separate count, the complaint alleges that Defendant "has been and continues to directly infringe" and "continues to make, use, test, sell, offer for sale" infringing products despite having "actual knowledge" from the complaint and its attached charts (Compl. ¶¶23, 25-26, 44, 46-47). The prayer for relief seeks enhanced damages for infringement of the ’321 and ’685 Patents, which is predicated on a finding of willfulness (Compl. ¶P).

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

• A core issue will be one of definitional scope: can the term "remote printer," rooted in the patents’ disclosure of consumer-oriented photo printing, be construed broadly enough to cover Defendant’s industrial printing and coding systems? The resolution of this question will likely determine the applicability of a significant portion of the asserted patent portfolio.
• A second central question will be one of technical and evidentiary alignment: assuming the claim terms are construed broadly enough, what evidence will Plaintiff present to demonstrate that Defendant's products perform the specific, multi-step communication and processing protocols required by the claims? The dispute may turn on whether the accused systems' operations contain the particular steps of registration verification, security-indicator-based error checking, and RAMdisk-based print queuing as recited in the asserted claims.
