  • Plaintiff’s Counsel: Stamoulis & Weinblatt LLC; Budo Law, LLP
• Case Identification: 1:19-cv-01482, D. Del., 08/08/2019
• Venue Allegations: Venue is alleged to be proper in the District of Delaware because the Defendant is a Delaware corporation.
• Core Dispute: Plaintiff alleges that Defendant’s hard drives, which feature QR codes that link to product information webpages when scanned by a portable device, infringe a patent related to retrieving and displaying information about an object using its symbology.
• Technical Context: The technology at issue involves using machine-readable symbols, like QR codes, on physical products to provide consumers with access to digital information via portable electronic devices such as smartphones.
• Key Procedural History: The asserted patent is subject to a terminal disclaimer in view of U.S. Patent No. 7,992,773, which issued from a parent application. This may limit the enforceable term of the patent-in-suit.

Case Timeline

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

U.S. Patent No. 8,424,752 - System and method for presenting information about an object on a portable electronic device

The patent-in-suit is U.S. Patent No. 8,424,752 (“the ’752 Patent”), which issued on April 23, 2013.

The Invention Explained

• Problem Addressed: The patent describes a situation where users own portable electronic devices with numerous applications, making it potentially difficult for a user to select the appropriate application for scanning a product's symbology to retrieve information. (’752 Patent, col. 3:35-39).
• The Patented Solution: The invention provides a method where a portable electronic device captures an image of a symbol (e.g., a barcode) on an object, decodes it locally to get a "decode string," sends that string to a remote server, receives information back from the server, and displays it. (’752 Patent, Abstract; Fig. 7B). The process is designed to streamline the retrieval of object-specific information using a portable device. (’752 Patent, col. 2:56-62).
• Technical Importance: The claimed method provides a framework for linking physical objects to digital information, a process that became commercially significant with the widespread adoption of smartphones with cameras and constant internet connectivity.

Key Claims at a Glance

• The complaint asserts at least independent claim 1. (Compl. ¶17).
• The essential elements of Claim 1 are:
  • A method comprising:
  • capturing a digital image using a digital image capturing device that is part of a portable electronic device;
  • detecting symbology associated with an object within the digital image using a portable electronic device;
  • decoding the symbology to obtain a decode string using one or more visual detection applications residing on the portable electronic device;
  • sending the decode string to a remote server for processing;
  • receiving information about the object from the remote server wherein the information is based on the decode string of the object;
  • displaying the information on a display device associated with the portable electronic device.
• The complaint notes that infringement is alleged on "one or more claims," reserving the right to assert others. (Compl. ¶17).

III. The Accused Instrumentality

Product Identification

The accused instrumentalities are Western Digital products that implement QR code functionality, such as the WD Blue Desktop Hard Drive. (Compl. ¶11; Fig. 1). The complaint includes an image of the accused hard drive, which displays a QR code on its label. (Compl. Fig. 1).

Functionality and Market Context

The complaint alleges that the accused hard drives are affixed with QR codes. (Compl. ¶22). When a user scans this code with a portable device like a smartphone, an application on the device decodes the symbol into a hyperlink. (Compl. ¶20). The device then accesses this hyperlink, which directs it to a remote server controlled by the Defendant. (Compl. ¶20). This server returns product-specific information that is then displayed on the user's device. (Compl. ¶21). This functionality is allegedly used for product marketing and customer support.

IV. Analysis of Infringement Allegations

’752 Patent Infringement Allegations

Identified Points of Contention

• Direct vs. Indirect Infringement: The complaint alleges direct infringement by Defendant through internal testing and troubleshooting. (Compl. ¶16). However, the core allegations describe a method performed by an end-user with their own portable device interacting with Defendant's server. This raises the question of whether Plaintiff can prove Defendant itself performed every step of the claimed method. The alternative theory of induced infringement will depend on whether placing a QR code on a product constitutes an affirmative act with the intent to cause infringement by end-users.
• Technical Questions: The complaint alleges that a smartphone application "decodes the digital image captured on the smartphone camera to produce a decoded hyperlink." (Compl. ¶20). A factual question will be whether the specific applications used by consumers to scan the accused products operate in a manner that meets the claim limitation of "decoding the symbology... using one or more visual detection applications residing on the portable electronic device."

V. Key Claim Terms for Construction

• The Term: "visual detection applications residing on the portable electronic device"
• Context and Importance: The construction of this term is critical for determining where the "decoding" step must occur. Infringement of claim 1 requires that the decoding application resides on the portable device itself, rather than on a remote server. Practitioners may focus on this term because the location of the decoding process (local vs. remote) is a dispositive technical distinction.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The specification provides a non-exhaustive list of contemporary commercial scanning applications, such as "Neomedia's Neo Reader, Microsoft's Smart Tags, Android's Shop Savvy, Red Laser, ScanBuy, etc." ('752 Patent, col. 3:31-33). Plaintiff may argue this demonstrates an intent to cover a wide range of then-available local decoding apps.
  • Evidence for a Narrower Interpretation: The claim language explicitly requires the application to be "residing on the portable electronic device." Defendant could argue that this language was chosen to distinguish the invention from other potential architectures where an image of the symbology is sent to a server for remote decoding, and that any ambiguity should be resolved in favor of this narrower, local-only processing interpretation.

VI. Other Allegations

• Indirect Infringement: The complaint alleges inducement, stating Defendant took "active steps" by "advertising an infringing use" and "making, using, offering for sale, and/or selling... products affixed with QR codes that require the accused technology for intended functionality." (Compl. ¶22-¶23). These allegations are aimed at establishing Defendant’s intent for its customers to perform the patented method.
• Willful Infringement: Willfulness is alleged based on Defendant’s purported actual knowledge of the ’752 Patent, which Plaintiff claims Defendant had "at least [from] the filing and service of this complaint" and potentially from pre-suit "due diligence and freedom to operate analyses." (Compl. ¶27).

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

• A core issue will be one of liability for third-party acts: Can the plaintiff prove that Western Digital directly infringes by performing all claimed method steps during its own testing, or must the case proceed on a theory of indirect infringement? If the latter, the key question becomes whether providing a product with a QR code that links to the provider's own support website is sufficient to establish the specific intent required for inducement.
• A second central question will concern validity in view of prior art: The asserted claim recites a sequence of steps—scanning a code on a product with a phone, sending the resulting data to a server, and displaying the retrieved information. The case may turn on whether this combination was novel and non-obvious as of the 2010 priority date, or if it will be viewed as a conventional implementation of then-existing technologies.
• Finally, the dispute may involve a question of definitional scope: Does the term "visual detection applications residing on the portable electronic device" read on the standard, general-purpose QR code scanning functionality built into or downloaded onto modern smartphones, and does the evidence show these applications perform the "decoding" step locally as required by the claim?
