Coverage
What does this patent actually cover?
The patent describes a method for creating a frozen confection by placing a handle into a container of liquid, such as soda or fruit juice, and freezing the mixture until it becomes a solid block. The handle remains embedded in the frozen mass, allowing the user to hold the treat without touching the ice directly. This simple mechanical design allows for a portable, handheld frozen snack that melts slowly while being consumed.
The gap
What does this patent NOT cover?
- Does not cover non-frozen confections or candies.
- Does not cover liquid-based treats that do not utilize a handle or stick for consumption.
- Does not cover the chemical composition of the flavoring or the specific type of liquid used.
These exclusions are unique to PatentBrief — derived from the actual claim language, not patent-office boilerplate.
