Case Timeline

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

U.S. Patent No. 8,178,773 - "System and methods for the creation and performance of enriched musical composition"

The Invention Explained

• Problem Addressed: The patent describes traditional music composition as linear and pre-determined, where a performer's role is to accurately reproduce the content, offering limited freedom to innovate or create unique performances from a shared musical foundation (’773 Patent, col. 3:4-13, col. 13:39-55).
• The Patented Solution: The invention is a system allowing a composer to package sensory content (e.g., musical clips) into "programs" and associate them with user-activated "triggers" (such as GUI buttons, keyboard keys, or light beams) (’773 Patent, Abstract). A performer can activate these triggers to generate a real-time musical performance. The system is designed so that the pre-packaged content segments are "sympathetic," ensuring that even a novice performer can create a composition that is musically pleasing (’773 Patent, col. 2:44-48). The system can further divide a song into sections like a "verse" and "chorus," with the available triggered content changing as the song progresses through these sections (’773 Patent, col. 2:48-54).
• Technical Importance: This technology aims to enable interactive music creation by non-experts, allowing for the generation of complex, non-linear musical arrangements that remain harmonically and rhythmically coherent (’773 Patent, col. 2:44-48).

Key Claims at a Glance

• The complaint does not identify specific asserted claims, instead referring to "exemplary claims" (Compl. ¶11). Claim 1 is the first independent claim of the patent.
• Independent Claim 1:
  • A music instrument configured to allow a user to compose interactive musical sounds, comprising:
  • a plurality of triggers configured to be controlled by a user;
  • a processor configured to be controlled by a graphical user interface ("GUI");
  • a controller responsive to the plurality of triggers, and configured to generate control signals as a function of the triggers selected by the user;
  • a plurality of music programs, wherein each said music program is mapped and composed into related components and configured to play sympathetic sounds in real time, the processor configured to generate an electronic signal as a function of the controller control signals and the related components of the plurality of mapped and composed music programs; and
  • at least one sound generator configured to generate the sympathetic sounds as a function of the related components of the mapped and composed music programs.
• The complaint does not explicitly reserve the right to assert dependent claims.

III. The Accused Instrumentality

Product Identification

The complaint alleges infringement by "Exemplary Defendant Products" identified in charts incorporated into the complaint (Compl. ¶11). These charts are referenced as Exhibit 2, which was not provided with the complaint document (Compl. ¶17).

Functionality and Market Context

The complaint does not provide sufficient detail for analysis of the accused products' functionality or market context.

IV. Analysis of Infringement Allegations

The complaint references claim charts in an external "Exhibit 2" to detail its infringement allegations; this exhibit was not provided with the filed complaint (Compl. ¶¶17-18). The complaint's narrative states that these charts demonstrate that the "Exemplary Defendant Products practice the technology claimed by the ’773 Patent" (Compl. ¶17). Without the charts, a detailed analysis of the specific infringement theory is not possible.

No probative visual evidence provided in complaint.

• Identified Points of Contention: Based on the patent claims and the general nature of the allegations, the infringement analysis may raise several questions:
  • Scope Questions: The claims are directed to a "music instrument." A threshold question for the court will be whether this term, as defined in the patent, can be construed to read on the accused instrumentalities, which are not specified but could potentially be software applications, hardware synthesizers, or a combination thereof.
  • Technical Questions: A key technical question will concern the "plurality of music programs" limitation. The analysis will require determining if the accused products possess data structures that meet the claim's requirements of being "mapped and composed into related components" and functionally "configured to play sympathetic sounds in real time" (’773 Patent, col. 28:50-55).

V. Key Claim Terms for Construction

• The Term: "sympathetic sounds"

  • Context and Importance: This term appears in independent claim 1 and is central to the invention's stated purpose of enabling even a novice to create a "pleasing" performance. Practitioners may focus on this term because its construction will determine the standard for infringement—whether it requires a specific, objective technical outcome (e.g., harmonic and rhythmic compatibility) or a more subjective, functional quality.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The specification describes the concept in general terms, stating the content is chosen so that "the sensory stimulating data is presented in a pleasing and sympathetic manner" (’773 Patent, col. 2:44-48).
    • Evidence for a Narrower Interpretation: The specification provides more concrete examples, such as a "looped drum track" or content that works together without a "clash," which suggests a more technical definition related to pre-selected rhythmic and harmonic compatibility (’773 Patent, col. 2:40-45, col. 2:66-68).

• The Term: "music program"

  • Context and Importance: This is a core structural element of the claimed system. The infringement analysis will depend on whether the architecture and data organization of the accused products align with the definition of a "music program."
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The specification broadly defines a program as a way to "arrange and package sensory stimulating content" for use by a performer (’773 Patent, col. 2:51-54).
    • Evidence for a Narrower Interpretation: The patent details specific implementations where programs contain "segments" of content (like MIDI files or sound recordings), are created via specific GUI editors (as shown in Fig. 7 and Fig. 11), and are associated with triggers (’773 Patent, col. 2:58-61, col. 11:3-36). This could support a narrower construction requiring a specific, structured data entity.

VI. Other Allegations

• Indirect Infringement: The complaint alleges that Defendant induces infringement by distributing "product literature and website materials" that instruct end users to use the products in an infringing manner (Compl. ¶14). It also alleges contributory infringement, stating the products are not a "staple article of commerce suitable for substantial noninfringing use" (Compl. ¶16).
• Willful Infringement: The complaint asserts that service of the complaint itself constitutes "actual knowledge" of infringement, and that Defendant's continued activities thereafter are willful (Compl. ¶¶13-14). No facts suggesting pre-suit knowledge are alleged.

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

1. Evidentiary Specificity: A threshold issue is the lack of detail in the complaint, which defers all specific infringement allegations to an un-provided exhibit. The initial phase of the case will revolve around discovering Plaintiff's precise infringement theory, including the identity of the accused products and the specific features alleged to meet each claim limitation.
2. Definitional Scope: The case will likely turn on the construction of foundational claim terms like "music instrument" and "sympathetic sounds." The central legal question will be whether the patent's specification supports a definition broad enough to encompass the architecture and functionality of Defendant's modern music creation products.
3. Indirect Infringement and Intent: Given that the patent claims a system for a user to "compose interactive musical sounds," the allegations of indirect infringement will be critical. A key evidentiary question will be whether Plaintiff can demonstrate that Defendant, through its manuals and marketing, specifically intended for its customers to use its products in a manner that directly infringes the method articulated in the patent claims.
