Obviousness

An analysis of US Patent 11,733,009 under 35 U.S.C. § 103 indicates that its claims would likely have been obvious to a person having ordinary skill in the art (PHOSITA) by the patent's earliest priority date of September 2, 2016. The motivation to combine the identified prior art references stems from a continuous desire in the pyrotechnics industry to enhance safety, improve convenience, offer greater customization, and enrich the user experience for both professional and consumer fireworks displays.

The core inventive concepts of US11733009, which include mobile device control, music synchronization, safety features (like location-based warnings), simulation, and improved detonator hardware, are each addressed by various prior art references.

Combinations of Prior Art Rendering Claims Obvious:

1. Mobile Control of Music-Synchronized Fireworks Displays:

• Prior Art:
  • US5339741A (filed 1993-01-04, granted 1994-08-23) describes a "Precision fireworks display system" that can synchronize projectile explosions to "music, dialogue or other sounds" using an "electronic control system".
  • Professional pyrotechnic systems, such as those described by "Outdoor Displays - Gateway Fireworks" and "PYRODIGITAL PHASE III", were well-established in choreographing fireworks to music using computer-controlled firing systems that send time signals to field modules.
  • "MK802 and IPhone: a fireworks remote control." (August 2, 2012) demonstrates using an iPhone's Wi-Fi to control fireworks ignition via a relay.
  • "Remote Fireworks Launcher | Savi Technologies" (July 6, 2013) explicitly aims to use a "tablet computer to remotely ignite fireworks" with an "Android tablet with custom launch app" communicating via "bluetooth serial profile". Its companion, "Fireworks Tablet App | Savi Technologies" (July 6, 2013), details a user interface for triggering igniters.
• Motivation to Combine: A PHOSITA would be motivated to combine the established technology of music-synchronized fireworks displays (US5339741A) with the convenience and widespread accessibility of mobile device control (Savi Technologies, MK802/iPhone). The integration would allow users to design and execute complex pyromusical shows from a portable, intuitive interface, thereby democratizing sophisticated fireworks choreography. The development of a mobile application to allow users to define sequences or synchronize with audio, as described in US11733009's claims, would be a logical extension of existing remote control and display programming capabilities.

2. Integration of Simulation and Safety Features in Mobile-Controlled Systems:

• Prior Art:
  • Building upon the mobile-controlled, music-synchronized systems discussed above.
  • For Simulation: "Fireworks Artist Lite" (available since at least May 23, 2013) and "PyroCreator 4D" (first released 1995) offered genuine fireworks simulation where users could design shows. "FWsim" also provided software for creating virtual fireworks displays with music.
  • For Safety: Concerns about safe distances from detonators were known, as evidenced by "SAFETY GUIDE FOR THE PREVENTION OF RADIO FREQUENCY RADIATION HAZARDS..." (December 20, 2011), which discussed safe distances for cellular phones from electric detonators. Regulations regarding fireworks exclusion zones were also in place in various localities. Professional systems like those from Dyno Nobel (August 25, 2016) incorporated security features (smart keys, passwords) and specified maximum firing distances for remote blasting. The "Wireless Firework Igniter : 5 Steps (with Pictures)" (June 27, 2015) included LEDs to indicate system status and a key switch as basic safety measures.
• Motivation to Combine: A PHOSITA would be motivated to incorporate simulation features into a mobile fireworks control application to provide users with a visual preview of their custom shows, reducing trial-and-error and improving the design process. Furthermore, the imperative for safety in pyrotechnics would drive a PHOSITA to integrate mobile device capabilities (e.g., GPS) to implement location-based safety features. Given the known hazards and regulations, providing warnings or preventing firing if a mobile device is too close or too far from the fireworks, leveraging existing GPS technology and the processing power of a smartphone, would be an obvious and desirable enhancement to a mobile control system.

3. Enhanced Firing Modules with Status Indicators and Secure Fuse Connections:

• Prior Art:
  • For Firing Modules/Indicators: "4 CH 100m Wireless Remote Control Firework Ignitor System" describes a receiver box with "signal light" indicators to confirm correct fireworks connections. Similarly, the "Wireless Firework Igniter : 5 Steps (with Pictures)" used green and red LEDs to indicate power and fault conditions.
  • For Fuse Connections: "How to use Talon Firework Igniters - YouTube" (July 2, 2013) details igniters that clip onto a fuse, utilizing a "bridge wire" heating element and emphasizing proper insertion and continuity testing for reliable ignition. "Fireworks Electric Fuses | Savi Technologies" (July 6, 2013) describes wrapping nichrome wire around a fuse and securing it with hot glue and tape. Commercial fuse connectors like "Fuse ConneX" and "Firework Junction" provided secure mechanical connections for fuses using features like lids, latches, and serrated teeth to ensure proper contact and heat transfer.
• Motivation to Combine: A PHOSITA would aim to improve the reliability and safety of the physical interface between the firing module and the fireworks. Given the existence of igniters that securely attach to fuses and the use of status indicators on firing systems, it would be obvious to design a firing module (as described in US11733009) with integrated connection status indicators (e.g., LEDs) for each detonator. Incorporating a robust "fuse connection assembly" on detonation wires, possibly with a cover or latch to securely engage the fuse with the heating element (as taught by various fuse connector solutions), would be a logical step to ensure consistent and reliable ignition and prevent accidental dislodgement, thereby enhancing overall system safety and performance.

In conclusion, the various elements of US Patent 11,733,009, when viewed in light of the prior art available before September 2, 2016, represent obvious combinations of known technologies. A PHOSITA would have been motivated to integrate these existing features to create a more user-friendly, safer, and highly customizable automated fireworks display system.
