U.S. Patent No. 10,140,071 - "Printers, printer controllers, printer software, or printer firmware for supporting wireless printing or printing over air"

• Patent Identification: U.S. Patent No. 10,140,071, "Printers, printer controllers, printer software, or printer firmware for supporting wireless printing or printing over air," issued November 27, 2018 (the "'071 Patent").

The Invention Explained

• Problem Addressed: The patent's background section describes the inconvenience for users of mobile devices who need to print content. Conventional methods required the pre-installation of a device-specific driver for each printer, a process that is particularly burdensome for mobile users who may encounter various printers at remote locations and whose devices have limited storage and processing power '071 Patent, col. 2:15-24 '071 Patent, col. 3:5-14
• The Patented Solution: The invention proposes a system where the computational load of raster image processing (RIP) is shared between a mobile "information apparatus" and an "output device" (e.g., a printer). The mobile device performs an initial rasterization to create a device-independent "intermediate output data," which it sends to the printer. An "output controller" in the printer then performs the remaining, more device-specific processing, such as halftoning and color correction, before rendering the final output '071 Patent, abstract '071 Patent, col. 5:35-col. 6:2 This balanced approach allows for universal output capability without requiring a dedicated driver for each printer.
• Technical Importance: This distributed processing model was significant for enabling pervasive computing by allowing resource-constrained mobile devices to offload computationally intensive tasks to peripherals, simplifying the user experience for mobile printing '071 Patent, col. 3:41-52

• No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

The complaint alleges infringement of its patents but relies on references to claim charts in Exhibits 10-18, which were not provided with the complaint itself Compl. ¶75 The narrative infringement theories are summarized below.

'181 Patent Infringement Allegations

The complaint alleges that Defendants directly infringe at least claim 1 of the '181 Patent by making, using, and selling the Accused Printers in the United States Compl. ¶82 It further alleges that Defendants indirectly infringe by inducing their customers to use the Accused Printers in a manner that directly infringes at least claim 1 Compl. ¶83 The specific details of this infringement theory are purportedly contained in the unprovided Exhibit 10 Compl. ¶84

'071 Patent Infringement Allegations

The complaint alleges direct infringement of at least claim 1 of the '071 Patent through the making, using, and selling of the Accused Printers Compl. ¶89 The infringement theory likely centers on the printers' alleged functionalities of storing a device profile, using IEEE 802.11-compatible wireless chips to broadcast availability, and receiving print data conforming to that profile, which would map to the elements of claim 1. The complaint also alleges inducement of customers to use the printers in an infringing manner Compl. ¶90 The detailed infringement allegations are referenced in the unprovided Exhibit 11 Compl. ¶91

• Identified Points of Contention:
  • Scope Questions: Claim 1 of the '071 Patent recites a "printing device" that performs several functions, including "wirelessly broadcast[ing] availability." A question for the court will be whether the accused Kyocera printers perform this function themselves. If the discovery function is instead performed primarily by the mobile app or a network server, it may raise questions of divided infringement, where multiple actors collectively perform the steps of a claim.
  • Technical Questions: A key technical question will be whether the information transmitted from the Accused Printers to the Accused Apps constitutes an "output device profile" as required by claim 1. The analysis will likely focus on whether the transmitted data includes substantive technical parameters for rendering (e.g., resolution, color space, halftoning methods) as described in the patent's specification, or if it is merely identification data such as a device name, and whether the latter is sufficient to meet the claim limitation.

V. Key Claim Terms for Construction

• The Term: "output device profile" ('071 Patent, claim 1)

• Context and Importance: This term is critical because infringement of claim 1 requires the accused printing device to store and transmit "at least part of an output device profile." The definition will determine whether the data allegedly stored and transmitted by the Accused Printers-which could range from a simple device name to a complex set of technical specifications-falls within the scope of the claim.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The specification states that a profile "may contain one or more" of a long list of fields and that each field "may be optional" '071 Patent, col. 9:60-65 This language may support an argument that even a minimal set of information (e.g., just the device name or model) constitutes "part of" the profile.
  • Evidence for a Narrower Interpretation: The patent frequently describes the profile in a technical context, linking it to parameters needed for rendering, such as "resolution, halftoning methods, dpi," and "color space" '071 Patent, col. 10:11-15 This may support an argument that the term requires a technically substantive set of data beyond mere device identification.

• The Term: "wirelessly broadcast availability" ('071 Patent, claim 1)

• Context and Importance: This term defines an active step that the "printing device" itself must perform. Whether the accused Kyocera printers "broadcast" their availability, or are merely passive devices discovered by the mobile app's active searching, will be central to the direct infringement analysis. Practitioners may focus on this term to explore a potential divided infringement defense.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The patent describes a discovery process where an information apparatus can search for available devices, which in turn "respond" or have their services registered with a control point '071 Patent, col. 31:30-44 This could support a reading where any form of participation in a discovery protocol that results in the printer's availability being known constitutes a "broadcast."
  • Evidence for a Narrower Interpretation: The term "broadcast" has a specific technical meaning in networking (sending a packet to all devices on a subnet). A defendant could argue that a more passive or targeted response to a specific query (e.g., a multicast service discovery query) is not a "broadcast." The patent also distinguishes between a device "broadcasting or advertising" its service and an apparatus "listening to" broadcasts, suggesting a potential distinction between active and passive roles '071 Patent, col. 31:33-36

VI. Other Allegations

• Indirect Infringement: The complaint alleges induced infringement for all asserted patents, claiming Defendants' product manuals, websites, and marketing activities instruct and encourage customers to use the Accused Products in an infringing manner Compl. ¶70; Compl. ¶83; Compl. ¶90 For the '031 Patent, the complaint also alleges contributory infringement, asserting that the Accused Apps constitute a material part of the invention, are not a staple article of commerce, and are known to be especially made for use in an infringing manner Compl. ¶105
• Willful Infringement: The complaint alleges willful infringement for all asserted patents based on Defendants' alleged knowledge of the patents since at least July 23, 2021, and October 29, 2021, via notice letters Compl. ¶¶72; Compl. ¶85 The complaint alleges that despite this pre-suit knowledge, Defendants continued their infringing activities without seeking to remedy the infringement or identifying a good-faith belief of non-infringement Compl. ¶86

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

• A core issue will be one of claim scope and divided infringement: can claim limitations directed to a single "printing device" that performs functions like "broadcasting availability" and transmitting a "profile" be met by a multi-component system of a printer, a smartphone, and a mobile application? The court will have to determine whether the accused printers perform the claimed functions themselves or if liability depends on combining the actions of separate devices and software, raising complex questions of divided and indirect infringement.
• A key evidentiary question will be one of technical satisfaction: does the data that the accused Kyocera printers allegedly transmit to the mobile app constitute an "output device profile" as that term is used in the patents? The case may turn on evidence showing whether this transmitted data contains the substantive rendering parameters (e.g., resolution, color space) described in the specifications or is merely identifying information, and whether the latter is sufficient to meet the claim limitation.
• A central question for damages will be willfulness: given the specific pre-suit notice letters alleged in the complaint, the court will examine Defendant's conduct after being notified of the patents. The determination will likely depend on evidence of whether Defendant investigated the claims in good faith and formed a reasonable, objectively-held belief of non-infringement or invalidity to rebut the charge of wanton and deliberate disregard for Plaintiff's patent rights.
