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,” issued April 23, 2013
The Invention Explained
- Problem Addressed: The patent's background describes an environment where portable electronic devices contain numerous applications, which may make it difficult for a user to select the appropriate one for a specific function, such as scanning a symbol to get information about an object (’752 Patent, col. 3:34-40).
- The Patented Solution: The invention provides a method and system to streamline this process. A portable device captures an image of symbology (e.g., a barcode), which is then decoded to produce a "decode string." This string is sent to a remote server, which returns information about the associated object for display on the device (’752 Patent, Abstract; col. 2:2-16). The system is designed to automate the selection of the correct scanning/decoding application and integrate information retrieval (’752 Patent, col. 3:41-51).
- Technical Importance: The technology aimed to simplify the user experience by automating the process of identifying an object via its barcode or symbol and retrieving relevant data, a key feature as app-enabled smartphones became ubiquitous (’752 Patent, col. 3:29-33).
Key Claims at a Glance
- The complaint asserts infringement of at least Claim 6, which is dependent on independent Claim 1 (Compl. ¶23).
- Independent Claim 1 recites the following essential elements:
- capturing a digital image using a digital image capturing device that is part of a portable electronic device;

Technology Synopsis
- As another member of the same patent family, this patent discloses a system for using a portable electronic device to retrieve information about an object. The described method involves capturing a digital image containing symbology, decoding it on the device, sending the resulting data to a remote server, and receiving back information for display (’190 Patent, Abstract; col. 2:10-24).
Asserted Claims
- The complaint asserts at least Claim 6, which is dependent on independent Claim 1 (Compl. ¶51).
Accused Features
- Plaintiff alleges that Defendant's system of placing QR codes on product packaging, which, when scanned by a user's device, causes the device to retrieve and display information from a remote server, infringes the patent (Compl. ¶¶51-57).
III. The Accused Instrumentality
Product Identification
- The accused instrumentality is Defendant's system and method of using Quick Response (QR) codes on its product packaging (Compl. ¶23). The complaint includes a photograph showing an example of such packaging with a QR code (Compl. ¶25, p. 6).
Functionality and Market Context
- The complaint alleges that Defendant incorporates QR codes into its product packaging, associating them with its products and services (Compl. ¶24).
- The alleged functionality involves a user employing a portable electronic device, such as a smartphone, to capture a digital image of the QR code (Compl. ¶26). Scanning technology on the device then decodes the symbol to obtain a "decode string," which is sent to a remote server (Compl. ¶27). In response, the server returns product-related information, such as a website, which is then displayed on the user's device (Compl. ¶¶27-28).
- The complaint provides a screenshot from a portable device allegedly showing the result of scanning a QR code: a webpage on "batterychargers.com" displaying information about a Schumacher Electric product (Compl. ¶28, p. 7).

Identified Points of Contention
- Scope Questions: A central dispute may arise over the construction of the term "one or more visual detection applications residing on the portable electronic device." The defense may argue that this term, in light of the patent's specification discussing a "symbology management module" (’752 Patent, Fig. 5), requires a specific type of managed software, not the generic, built-in QR code readers found on modern smartphones. The plaintiff may counter that any application performing the decoding function meets the limitation.
- Technical Questions: The complaint alleges direct infringement by the Defendant, stating "Defendant uses, inter alia, methods that perform all the steps" (Compl. ¶10) and that Defendant has "internally tested" the functionality (Compl. ¶25). However, the described infringing act is performed by an end-user scanning the QR code. This raises the question of what evidence Plaintiff will present to prove that Defendant itself performs all steps of the claimed method, as required for direct infringement.
V. Key Claim Terms for Construction
- The Term: "one or more visual detection applications residing on the portable electronic device"
- Context and Importance: This limitation from Claim 1 is the element that performs the "decoding" step. Its construction is critical because the outcome of the infringement analysis may depend on whether generic QR code scanning software on a standard smartphone qualifies as the claimed "application." Practitioners may focus on this term because the patent specification describes a more complex system than what is typically used today.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The claim language itself is broad, not explicitly limiting the "application" to one that interacts with a management module. A party could argue that any software on the device that performs the function of decoding symbology meets this definition.
- Evidence for a Narrower Interpretation: A party could argue for a narrower construction by pointing to the specification's detailed description of a "symbology management module 80" that controls various applications, including an "image capture application 110" and a "scanning application 112" (’752 Patent, Fig. 5; col. 11:1-10). This could support an argument that the claimed "application" must be part of such a managed ecosystem, not just a standalone decoder.
VI. Other Allegations
- Indirect Infringement: The complaint does not plead a cause of action for indirect infringement (inducement or contributory infringement). The counts are limited to direct infringement under 35 U.S.C. § 271 (Compl. ¶¶21, 35, 49).
- Willful Infringement: The complaint alleges that Defendant has had knowledge of its infringement "at least as of the service of the present complaint" for all three patents-in-suit (Compl. ¶¶22, 36, 50). This allegation supports a claim for post-filing willfulness only, as no facts suggesting pre-suit knowledge are pleaded. The prayer for relief seeks enhanced damages pursuant to 35 U.S.C. §285 (Compl. p. 15).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of claim scope: can the term "visual detection applications residing on the portable electronic device," which is described in the specification as part of a managed software ecosystem, be construed broadly enough to read on the generic, built-in QR code scanning functionality of a typical modern smartphone?
- A key evidentiary question will be one of direct infringement: given that the infringing conduct described is performed by an end-user, what proof will Plaintiff offer to establish that Defendant Schumacher Electric itself "uses" the claimed method and performs every claimed step, as is required to prove direct infringement?
