Harman Intl Industries Inc v. Voxx Intl Corp
I. Executive Summary and Procedural Information
- Parties & Counsel:
- Plaintiff: Harman International Industries, Inc. (Delaware)
- Defendant: Voxx International Corp. (Delaware) and Klipsch Group, Inc. (Indiana)
- Plaintiff’s Counsel: DLA Piper LLP (US)
- Case Identification: 1:24-cv-01411, D. Del., 12/24/2024
- Venue Allegations: Plaintiff Harman alleges venue is proper in the District of Delaware because Defendant Voxx International is a Delaware corporation that resides in the district. Venue over Klipsch is alleged based on its status as a mere alter ego of Voxx.
- Core Dispute: Plaintiff alleges that Defendants’ Klipsch Gig XXL Party Speaker infringes thirteen of Harman's design patents covering the ornamental appearance of its own JBL PartyBox line of illuminated speakers.
- Technical Context: The dispute centers on the ornamental design of large, portable "party speakers," a consumer electronics category where aesthetic features, such as integrated light shows, are a significant market differentiator.
- Key Procedural History: The complaint details extensive pre-suit communications, alleging that Harman first notified Defendants of five asserted patents on September 1, 2023. Harman alleges it reiterated its infringement contentions in subsequent communications in September and October 2023, and that Defendants proposed a redesign that was never implemented. This history forms the basis for the willfulness allegations.

II. Technology and Patent(s)-in-Suit Analysis
U.S. Design Patent No. D913,991 - “Illuminated Loudspeaker,” issued March 23, 2021
The Invention Explained
- Problem Addressed: The complaint suggests the design aims to create a unique and aesthetically pleasing appearance for a portable loudspeaker, in order to "visually distinguish" it from other products on the market (Compl. ¶34).
- The Patented Solution: The patent claims the specific ornamental design for an illuminated loudspeaker face (Compl. ¶35). The design, as shown in the patent's figures, consists of an animated sequence of illuminated patterns around two circular speaker drivers. Critically, the rectangular speaker housing itself is depicted in broken lines, indicating it is not part of the claimed design; the claim is limited to the appearance of the illumination sequence itself (’991 Patent, Figs. 1-6).
- Technical Importance: In the competitive consumer electronics market, unique aesthetic designs, particularly dynamic lighting features, serve as a key differentiator to attract consumers and build brand identity (Compl. ¶31, ¶34).
Key Claims at a Glance
- The patent contains a single claim for "The ornamental design for an illuminated loudspeaker, as shown and described" ('991 Patent, Claim).
- The core visual elements of the claimed design are the shape, arrangement, and animated sequence of the illuminated light rings on the face of a loudspeaker.
U.S. Design Patent No. D914,639 - “Illuminated Loudspeaker,” issued March 30, 2021
The Invention Explained
- Problem Addressed: Similar to the '991 Patent, this design patent seeks to protect a unique and ornamental appearance for an illuminated loudspeaker to distinguish it in the marketplace (Compl. ¶34, ¶37).
- The Patented Solution: This patent claims an ornamental design for the illuminated portion of a loudspeaker face (’639 Patent, DESCRIPTION). Unlike the animated sequence in the '991 patent, this patent claims a static illumination pattern. The claimed design consists of two illuminated C-shaped arcs surrounding two circular areas. As with the '991 patent, the speaker housing and other features are shown in broken lines, indicating that only the illuminated pattern itself is being claimed ('639 Patent, FIGURE).
- Technical Importance: Protecting static lighting patterns, in addition to animated sequences, allows a patentee to secure a broader set of aesthetic features that contribute to a product line's overall design language (Compl. ¶33).
Key Claims at a Glance
- The patent contains a single claim for "The ornamental design for an illuminated loudspeaker, as shown and described" ('639 Patent, Claim).
- The core visual elements are two static, arc-shaped illuminated areas arranged vertically on a loudspeaker face.
Multi-Patent Capsule: D918,173; D921,612; D944,772; D1,000,419; D1,000,420; D1,001,775; D1,008,220; D1,011,314; D1,012,068; D1,012,897; and D1,030,706
- Technology Synopsis: Each of these eleven design patents claims an ornamental design for an "Illuminated Loudspeaker" (Compl. ¶¶39-60). The patents cover a family of related aesthetic features, protecting various static and animated illumination patterns. Some patents, like D'419 and D'420, claim only the illuminated arcs, while others, like D'897, claim the arcs in combination with the surrounding speaker grille and housing, presenting potentially different scopes of protection.
- Asserted Claims: The sole claim of each patent is asserted.
- Accused Features: The complaint alleges that the overall ornamental design of the Klipsch Gig XXL Party Speaker, particularly its front face and illuminated light rings, infringes each of these patents (Compl. ¶68).
III. The Accused Instrumentality
- Product Identification: Defendants’ "Gig™ XXL Party Speaker" (Accused Product) (Compl. ¶1).
- Functionality and Market Context: The Accused Product is a portable, powered loudspeaker featuring integrated, dynamic lighting effects that illuminate in various colors and patterns around its two main speaker drivers (Compl. ¶70, pp. 16-19). The complaint alleges that Defendants are competitors in the portable speaker market and that the Accused Product retails for substantially less than Harman's comparable JBL PartyBox products (Compl. ¶62, ¶64). The packaging and manual for the Accused Product allegedly feature branding from both Klipsch and Voxx International (Compl. ¶13). The complaint includes an image from the Klipsch website showing the Accused Product offered for sale (Compl. ¶67, Ex. 21-22).
IV. Analysis of Infringement Allegations
The complaint alleges that the design of the Accused Product is "substantially the same in overall appearance" to the claimed designs "through the eye of an ordinary observer" (Compl. ¶68). To support this, the complaint provides side-by-side visual charts comparing Defendants' product to Harman's commercial products and patent figures. One such chart compares the Klipsch Gig XXL to the JBL PartyBox 100 and a figure from the D'897 patent, showing a similar arrangement of two illuminated rings on a dark, rectangular speaker face (Compl. ¶70, p. 19). Another chart shows a similar comparison for the D'420 patent, focusing on the C-shaped illuminated arcs (Compl. ¶70, p. 17).
U.S. Design Patent No. D1,000,420 Infringement Allegations
| Claim Element (from sole claim, as depicted in Fig. 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| An ornamental design for an illuminated loudspeaker comprising two vertically-aligned, C-shaped illuminated arcs. | The Klipsch Gig XXL speaker displays two vertically-aligned, C-shaped illuminated arcs around its speaker drivers. | ¶70, p. 17; ¶153 | ’420 Patent, Fig. 1 |
| The upper arc is open on the right side. | The upper illuminated arc on the Accused Product is shown as being open on its right side. | ¶70, p. 17; ¶153 | '420 Patent, Fig. 1 |
| The lower arc is open on the left side. | The lower illuminated arc on the Accused Product is shown as being open on its left side. | ¶70, p. 17; ¶153 | '420 Patent, Fig. 1 |
U.S. Design Patent No. D1,012,897 Infringement Allegations
| Claim Element (from sole claim, as depicted in the FIGURE) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| An ornamental design for an illuminated loudspeaker including the speaker housing, grille, and illuminated elements. | The overall front-face design of the Klipsch Gig XXL speaker, including its housing, grille, and lights. | ¶70, p. 19; ¶208 | ’897 Patent, FIGURE |
| Two illuminated, parenthesis-shaped arcs surrounding two circular speaker drivers. | The Accused Product features two illuminated, parenthesis-shaped arcs around its two circular speaker drivers. | ¶70, p. 19; ¶208 | '897 Patent, FIGURE |
| The overall rectangular shape of the speaker face and perforated grille pattern. | The Accused Product has a similar rectangular shape and a perforated front grille. | ¶70, p. 19; ¶208 | '897 Patent, FIGURE |
Note: The analysis above uses the D'420 and D'897 patents, as the complaint's visual evidence at ¶70 most clearly illustrates the infringement theories for these representative patents.
- Identified Points of Contention:
- Scope Questions: A central issue will be the scope of each design patent. Some patents (e.g., D'420) use broken lines to disclaim the speaker housing, limiting the claim to the illumination pattern alone. Others (e.g., D'897) claim the illumination pattern in combination with the speaker grille and housing. This raises the question of whether the Accused Product, when viewed as a whole, is substantially similar to these different claimed scopes.
- Technical Questions: The infringement analysis for design patents is not technical but visual. The question for the fact-finder will be whether an "ordinary observer," familiar with the prior art designs of similar speakers, would be deceived by the similarity between the claimed designs and the Accused Product. Defendants may argue that differences in branding, the precise curvature of the light arcs, or other minor details are sufficient to distinguish the products in the eye of an ordinary observer.
V. Key Claim Terms for Construction
In design patent cases, the "claim" is understood through the drawings, not claim terms. The central interpretive issue is the scope of the claimed design as defined by the solid and broken lines in the patent figures.
- The Term: "The ornamental design for an illuminated loudspeaker"
- Context and Importance: The scope of what is protected—and therefore what is compared to the accused product—is defined by the patent figures. Practitioners may focus on the distinction between patents that claim only the light patterns and those that claim the light patterns plus the speaker housing, as this will alter the infringement analysis. A claim limited to the light pattern alone may be considered broader in some respects, as it is not tied to a specific speaker body.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation (focused on the light pattern): Patents like D'420 and D'419 show the entire loudspeaker housing in broken lines, disclaiming it as part of the invention ('420 Patent, Fig. 1; ’419 Patent, Fig. 1). This suggests the claim covers the specific illuminated arc design on any loudspeaker, which may support a finding of infringement regardless of differences in the speaker housings.
- Evidence for a Narrower Interpretation (focused on the entire product): Patents like D'897 show the speaker housing, grille, and light patterns in solid lines ('897 Patent, FIGURE). This limits the claim to the overall combination of those specific features. An infringement analysis for this patent would require comparing the entire front face of the accused product, where minor differences in the housing or grille might become more significant to the overall visual impression.
VI. Other Allegations
- Indirect Infringement: The complaint alleges that Defendants induced infringement by "actively and knowingly inducing others to manufacture, offer for sale, and or sell the Accused Product" (Compl. ¶81). This is supported by allegations that Defendants distribute the Accused Product through a "nationwide network of affiliated and unaffiliated retailers" (Compl. ¶82).
- Willful Infringement: The complaint alleges that Defendants had actual notice of at least five of the asserted patents as early as September 1, 2023, through direct email communications to company executives (Compl. ¶¶73-75). It further alleges that Defendants continued their infringing conduct even after these communications and after proposing a product redesign that was never implemented (Compl. ¶¶77, 80). The complaint also alleges that Defendants' products were "copied from Harman's JBL products" (Compl. ¶92).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of claim scope and the ordinary observer test: Given the variations in claim scope across the thirteen asserted patents—some claiming only light patterns, others the entire speaker face—would an ordinary observer find the Klipsch Gig XXL to be substantially the same as each of these differently-scoped designs?
- A key evidentiary question will concern willfulness: Can Harman prove by clear and convincing evidence that Defendants acted with egregious misconduct, particularly given the detailed allegations of pre-suit notice, direct communications with executives, and continued sales after those communications?
- A final question will be one of damages and disgorgement: Should infringement be found, the case will focus on calculating either Harman's damages or, as specifically allowed for design patents under 35 U.S.C. § 289, a disgorgement of Defendants' "total profits" from the infringing product, an issue that may be heavily influenced by a finding of willfulness.
