Case Timeline

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

• U.S. Patent No. 8,788,360, "SYSTEMS AND METHODS FOR AUTOMATED MASS MEDIA COMMERCE," issued July 22, 2014

The Invention Explained

• Problem Addressed: The patent's background section describes the high level of consumer effort traditionally required to act on an advertisement, such as remembering a phone number or URL from a magazine or billboard. This friction can cause consumers to "simply lose interest in an advertised product or service as time goes by." (’360 Patent, col. 1:37-44).
• The Patented Solution: The invention proposes a system to automate this process. A wireless identifier, such as a Radio Frequency Identification (RFID) tag, is attached to or embedded in a "mass media publication" like a magazine or billboard (’360 Patent, col. 4:56-64). A consumer uses a portable device, such as a smartphone, equipped with a reader to scan the tag. The device then uses the information from the tag to automatically generate and send a request over a network to a vendor's system, either to purchase the advertised item or request more information (’360 Patent, Abstract; Fig. 1).
• Technical Importance: The described system aims to reduce the barrier between advertisement exposure and commercial transaction, enabling "pervasive commerce with mass media publications." (’360 Patent, col. 1:20-22).

Key Claims at a Glance

• The complaint asserts "one or more claims" of the ’360 Patent without specifying them in the body of the complaint, but refers to "exemplary method claims" and "Exemplary '8788360 Patent Claims" in an incorporated exhibit (Compl. ¶¶11, 13). Independent claim 1, a system claim, is representative of the core invention.
• Independent Claim 1, a system claim, requires:
  • A "mobile ordering device" for a human consumer, which includes a radio frequency identification (RFID) reader configured to transmit a signal to and receive a response from an RFID tag attached to a "human-perceptible advertisement."
  • The mobile device is further configured to accept user input, generate an electronic request using information from the RFID tag, and communicate that request over a network.
  • A "commerce data system" that communicates with the mobile device over the network.
  • This commerce data system is for "receiving and processing the request" from the mobile device and "responding to the request by sending information" back to the mobile device.

III. The Accused Instrumentality

Product Identification

• The complaint does not identify any specific accused products by name. It refers generally to "Defendant products identified in the charts" and "Exemplary Defendant Products." (Compl. ¶¶11, 13).

Functionality and Market Context

• The complaint does not provide sufficient detail for analysis of the accused product's specific functionality or market context. It alleges that the "Exemplary Defendant Products practice the technology claimed by the '8788360 Patent." (Compl. ¶13).

IV. Analysis of Infringement Allegations

The complaint states that "Exhibit 2 includes charts comparing the Exemplary '8788360 Patent Claims to the Exemplary Defendant Products" (Compl. ¶13). However, this exhibit was not attached to the filed complaint document. The core infringement allegation is that the accused products "satisfy all elements of the Exemplary '8788360 Patent Claims" (Compl. ¶13). The complaint further alleges that Defendant directly infringed by "having its employees internally test and use these Exemplary Products" (Compl. ¶12). Without the specific claim charts or identification of the accused products, a detailed element-by-element analysis is not possible based on the provided documents.

No probative visual evidence provided in complaint.

Identified Points of Contention

• The bare-bones nature of the complaint defers the substantive dispute, but based on the patent's claims, key questions will emerge once the accused products are identified.
  • Factual Questions: A primary question will be identifying which Sony hardware, software, or services constitute the claimed "mobile ordering device" and the back-end "commerce data system." Evidence will be required to show that a specific Sony device contains an "RFID reader" that performs the functions recited in the claims.
  • Scope Questions: A likely point of contention will be whether the accused system's functionality meets the specific claim limitation of interacting with an RFID tag "attached with" a "human-perceptible advertisement." The nature of this attachment and the definition of "advertisement" in the context of the accused products will be critical.

V. Key Claim Terms for Construction

• The Term: "commerce data system"

• Context and Importance: This term appears in independent claim 1 and is central to the claimed system architecture. The defendant may argue that its back-end servers are general-purpose and do not meet the specific requirements of a "commerce data system" as described in the patent, while the plaintiff may argue for a broader definition. Practitioners may focus on this term because its construction could determine whether a standard web server is sufficient to meet the limitation, or if more specialized functionality is required.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: Claim 1 itself defines the system broadly as being "for receiving and processing the request... and responding to the request," which could be argued to cover any server that performs these basic network functions (’360 Patent, col. 7:27-33).
  • Evidence for a Narrower Interpretation: The detailed description suggests the "commerce data organization system" may have more specific functions, such as to "preserve and organize transaction details," "track or maintain product availability," and maintain "account information," which could support a narrower construction limited to systems with these e-commerce-specific features (’360 Patent, col. 5:4-18).

• The Term: "human-perceptible advertisement attached with at least one radio frequency identification (RFID) tag"

• Context and Importance: This limitation defines the trigger for the entire patented method. The dispute will likely focus on what constitutes an "advertisement" and what it means for a tag to be "attached with" it in the context of the accused products.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The term "mass media publication" is described broadly and could be argued to cover a wide range of modern digital and physical media (’360 Patent, col. 4:15-22).
  • Evidence for a Narrower Interpretation: The specification's examples focus heavily on physical print media, such as a "magazine, news paper, periodical, mailer, post card, outdoor or out-of-home media, billboard, bus shelter poster board," and RFID tags being "inserted, applied or incorporated into" them (’360 Patent, col. 4:15-19, 4:61-64). This could support an argument that the claims are limited to physical advertisements with physically associated tags, potentially excluding purely digital implementations.

VI. Other Allegations

• Indirect Infringement: The complaint does not allege indirect infringement.
• Willful Infringement: The complaint does not contain an allegation of willful infringement. It requests that the case be declared "exceptional" under 35 U.S.C. § 285, which is a separate legal standard related to case strength or litigation conduct (’Compl. ¶E.i.).

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

1. A threshold issue will be one of factual identification: what specific Sony products, software, and services comprise the accused system? The current complaint provides no details, and the entire case will depend on whether the features of the yet-to-be-identified products can be mapped onto the patent's claims.
2. The case will likely involve a significant dispute over claim scope: can the term "commerce data system," described in the specification with specific e-commerce functions, be construed to read on a general-purpose network server?
3. A central question will be the interpretation of the phrase "advertisement attached with... an RFID tag." The analysis will turn on whether the accused system involves a technology that functions as an "RFID tag" and whether it is "attached" to an "advertisement" in a manner consistent with the patent's disclosure, which emphasizes physical media.
