Is the Shake Weight Patented?

Quick answer

Yes — utility patent

Yes. Fitness IQ LLC holds a U.S. utility patent covering the Shake Weight's spring-loaded oscillating dumbbell mechanism.

What to know

• The product is widely mocked but the patent has been quietly enforced — knockoffs typically resort to identical mechanisms with renamed branding.
• The 6-month dynamic-inertia training claim is marketing language, not part of the patent claim itself.

Have your own invention idea?

If a product like Shake Weightcan get patent protection, your idea probably can too — assuming it’s novel. The cheapest first step is a provisional patent application, which locks in your priority date for 12 months while you validate the market. LegalZoom files provisionals from $199 + USPTO fees; you can also read the official USPTO patent basics first if you prefer.
