II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 7,365,649 - "Security Device and Methods for Security Device Operation", Issued April 29, 2008
The Invention Explained
- Problem Addressed: The patent describes the need to deter criminal activity by creating a convincing illusion of human occupancy. It notes that conventional methods like simple light timers are often not persuasive enough to mimic the specific light patterns of a television, a strong indicator that someone is home (’649 Patent, col. 1:5-19).
- The Patented Solution: The invention is a security device that uses a control circuit and an algorithm to vary the light output from elements like LEDs. This system is designed to specifically emulate the color, intensity, and flicker of a television program, with a particular focus on the "familiar blue flicker" that observers associate with a TV set (’649 Patent, Abstract; col. 2:2-6).
- Technical Importance: This approach provided a more sophisticated and energy-efficient method for simulating occupancy compared to leaving a real television on, which consumes significant power and may be subject to damage from power surges (’649 Patent, col. 2:7-12).
Key Claims at a Glance
- The complaint asserts infringement of "one or more claims" without specifying them (Compl. ¶24). Independent claim 1 is representative of the device:
- A security device comprising:
- a lighting fixture;
- a number of lighting elements, mounted to the lighting fixture;
- a control circuit, programmed to vary the luminosity and duration of drive currents provided to the lighting elements, in accord with an embedded algorithm;
- wherein the algorithm causes the lighting elements to undergo "a series of abrupt output changes" after the output has been uniform for a time, in conformity with "scene lengths of a television program."
U.S. Patent No. 7,755,470 - "Security Television Simulator", Issued July 13, 2010
The Invention Explained
- Problem Addressed: The patent identifies shortcomings in prior television simulators, which lacked the ability to convincingly mimic a modern television. It notes that simple strobing effects or static blue light fail to replicate the complex and dynamic nature of a real television's output, which includes fades, swells, abrupt changes, and subtle color shifts (’470 Patent, col. 2:5-24, col. 2:51-65).
- The Patented Solution: The invention describes a more advanced simulator using a plurality of light sources (e.g., different colored LEDs) and digital logic. This system generates a succession of "television-simulating program scene modes" where the type, amplitude, and duration of the modes are generated in a "random in manner" to create a more realistic and non-repeating light show (’470 Patent, Abstract; col. 4:38-54).
- Technical Importance: By incorporating multiple, randomly-occurring "scene modes" (such as static periods, fades, and flicks) and color variation, the invention aimed to create a far more believable simulation of an occupied home than was previously possible (’470 Patent, col. 2:51-65).
Key Claims at a Glance
- The complaint asserts infringement of "one or more claims" (Compl. ¶24). Independent claim 10 is a representative device claim:
- An intruder deterrent device that simulates an operating television by projecting light of varying amplitude from a plurality of light sources, wherein:
- the light comprises a succession of "television-simulating program scene modes";
- the occurrences of the scene mode types are "random in manner";
- the initial amplitudes of the scene modes are "random in manner"; and
- the durations of the scene modes are "random in manner."
U.S. Patent No. 7,719,435 - "Security Television Simulator with Realistic Emulation of Television Output", Issued May 18, 2010
- Technology Synopsis: This patent, related to the ’470 patent, details a method and apparatus for realistically simulating a television's light output to deter intruders. The technology uses combinations of multi-colored LEDs and digital logic to generate a variety of scene modes—including fades, swells, flicks, and static periods—whose combinations, amplitudes, and durations effectively emulate the complex light and color shifts of a real television program (’435 Patent, Abstract; col. 1:12-21).
- Asserted Claims: The complaint asserts "one or more claims" without specification (Compl. ¶24, ¶40). The patent includes independent claims 1 and 2.
- Accused Features: The complaint alleges that the accused "Jebsens" device, which it claims is a "near exact replica" of Plaintiff's product, infringes by projecting light patterns that simulate a television (Compl. ¶27, p. 8).
III. The Accused Instrumentality
- Product Identification: The accused products are sold under the brand name "Jebsens" and are described in the complaint as "Counterfeit Products" and "counterfeit versions of Plaintiff's FakeTV® products" (Compl. ¶3, ¶21).
- Functionality and Market Context: The accused products are alleged to be small, energy-efficient electronic devices that project light patterns to simulate a real television broadcast, serving as a burglar deterrent (Compl. ¶11). The complaint alleges these products are sold through online marketplaces such as Amazon.com and eBay.com (Compl. ¶7, ¶28). A central allegation is that the accused product is a "near exact replica" of Hydreon's own FTV-10 device (Compl. ¶27). The complaint provides a side-by-side photographic comparison of the Plaintiff’s FTV-10 device and the accused “JCB’s Jebsens Device,” alleging the latter is a “near exact replica” (Compl. ¶27, p. 8). This image shows two devices with nearly identical external housings, power cords, and front-facing light-emitting grids.
IV. Analysis of Infringement Allegations
The complaint does not contain a detailed, element-by-element infringement analysis. The infringement theory appears to rest on the allegation that the accused Jebsens product is a "near exact replica" of Plaintiff's own FakeTV® product, which presumably practices the patents-in-suit (Compl. ¶27). The following charts summarize the infringement allegations as they can be inferred from this core assertion.
’649 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| a lighting fixture; a number of lighting elements, mounted to the lighting fixture; | The accused device possesses a physical housing with a grid of light emitters, as shown in the photographic evidence presented as a "near exact replica" of Plaintiff's device. | ¶27, p. 8 | col. 3:13-17 |
| a control circuit, programmed to vary the luminosity and duration of the drive currents provided to each of the number of lighting elements... | The device is alleged to simulate a television, which inherently requires an internal control circuit to vary the light output in accordance with a program or algorithm. | ¶11, ¶24 | col. 3:21-25 |
| wherein the algorithm causes the number of lighting elements to undergo a series of abrupt output changes...in conformity with scene lengths of a television program. | The allegation that the product functions as a television simulator and is a "replica" of Plaintiff's product implies that its algorithm produces the abrupt light changes characteristic of TV scene changes. | ¶27 | col. 6:36-41 |
’470 Patent Infringement Allegations
| Claim Element (from Independent Claim 10) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| An intruder deterrent device that simulates an operating television by projecting light of varying amplitude from a plurality of light sources... | The accused device is alleged to be a television simulator that projects light patterns, which implies the use of multiple light sources to create varying amplitudes. | ¶11, ¶27 | col. 9:22-26 |
| (a) said varying amplitude light comprises a succession of television-simulating program scene modes, | The allegation that the device is a "Counterfeit Product" that infringes the patent implies that it generates the claimed "scene modes" (e.g., fades, flicks, static periods) required for a realistic simulation. | ¶3, ¶24 | col. 9:29-31 |
| (b) occurrences... (c) initial amplitudes... (d) durations of said program scene modes... are random in manner, | The complaint's allegation of infringement implies the accused device's operation is "random in manner" as required by the claim, a feature the patent teaches is key to a convincing, non-mechanistic simulation. | ¶24, ¶40 | col. 9:32-42 |
- Identified Points of Contention:
- Technical Questions: A primary evidentiary question will be whether the accused Jebsens device actually functions as alleged. Does its control logic generate "abrupt output changes" as required by the ’649 patent? Does its algorithm generate scene modes, amplitudes, and durations that are "random in manner" as required by the ’470 patent? The complaint's "near exact replica" allegation will likely need to be substantiated through discovery and reverse engineering of the accused product.
- Scope Questions: The dispute may raise questions about the scope of key claim terms. For example, what constitutes an "abrupt" change under the ’649 patent, and what level of unpredictability is required to meet the "random in manner" limitation of the ’470 patent?
V. Key Claim Terms for Construction
The Term: "abrupt output changes" (’649 Patent, Claim 1)
- Context and Importance: This term is central to distinguishing the patented invention from simpler flashing or strobing devices. The definition of "abrupt" will be critical to determining if the accused device's light variations meet this limitation.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The specification suggests this is tied to human perception, stating the changes occur "instantaneously as perceived by a human observer" and can be "in less than 0.1 seconds," which could be argued to cover a range of rapid transitions (’649 Patent, col. 5:11-14).
- Evidence for a Narrower Interpretation: The patent contrasts these "abrupt" changes with "gradual transitions" (’649 Patent, col. 5:9). A party could argue this requires a change with a specific, near-instantaneous quality that is distinct from other rapid variations.
The Term: "random in manner" (’470 Patent, Claim 10)
- Context and Importance: This limitation is the core of the ’470 patent's asserted improvement over prior art, ensuring the simulation is not repetitive or mechanistic. Infringement will depend heavily on whether the accused device's algorithm can be characterized as "random." Practitioners may focus on this term because it addresses the key technical feature alleged to create a more realistic simulation.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The related ’435 patent specification, which describes the same technology, states that "humans are remarkably good at recognizing even subtle patterns" and that an "obvious ruse can have the undesirable effect of confirming" a home is unoccupied (’435 Patent, col. 2:60-65). This could support a construction where "random in manner" means sufficiently complex to appear unpredictable to a human observer, even if algorithmically determined.
- Evidence for a Narrower Interpretation: The specification repeatedly refers to using a "pseudo-random generator," specifically a Linear Feedback Shift Register (LSFR), to achieve this effect (’435 Patent, col. 7:50-57). A party could argue that "random in manner" is not a general descriptor but is limited by these specific embodiments to devices that implement a recognized pseudo-random algorithm.
VI. Other Allegations
- Indirect Infringement: The complaint pleads inducement and contributory infringement (Compl. ¶40). The factual basis alleged is the act of selling and facilitating the sale of products that are "Counterfeit Products" and "near exact replicas," which may have no substantial non-infringing use (Compl. ¶26, ¶27).
- Willful Infringement: The complaint alleges that Defendant’s infringement is willful (Compl. ¶44). This allegation is supported by claims that Plaintiff became aware of Defendant's conduct in 2012 and that Defendant ignored a "cease and desist notice" from Plaintiff's counsel (Compl. ¶29, ¶37).
VII. Analyst’s Conclusion: Key Questions for the Case
- A key issue will be one of evidentiary proof: The complaint's infringement theory is heavily reliant on the factual assertion that the accused "Jebsens" device is a "near exact replica" of Plaintiff's product. A central question for the court will be whether technical analysis of the accused device confirms that its internal circuitry and control algorithm function identically to the patented technology.
- The case may also turn on a question of definitional scope: The construction of the term "random in manner" from the ’470 patent will likely be a focal point. The court will need to determine whether this term requires the implementation of a specific class of algorithm (such as the pseudo-random generators described in the specification) or if it can be satisfied by any process that creates light patterns appearing sufficiently non-repetitive to a human observer.
