Analysis of Obviousness for US Patent 12,491,430 under 35 U.S.C. § 103

Date of Analysis: May 13, 2026

Patent under Review: US Patent 12,491,430 B2 (henceforth '430 patent)

Invention: A puzzle platform comprising a puzzle board with a puzzle plate and at least one drawer, a kickstand to support the board at an incline, and a separate rotating device to allow the board to be rotated when not supported by the kickstand.

I. Understanding the '430 Patent Claims

The core of the '430 patent, as detailed in its abstract and claims, is a puzzle platform with two distinct operational modes.

1. Tilted Mode: A kickstand supports the puzzle board, inclining the puzzle plate and drawers for ergonomic use. In this mode, the rotating device is in a "non-working state."
2. Rotating Mode: The kickstand is in a "non-working state" (e.g., closed), and the puzzle board can be rotated on a flat surface via a rotating device, such as a Lazy Susan.

The claims also describe various configurations, such as the spatial relationship between the kickstand and the rotating device, including embodiments where their projections on the puzzle plate's plane do not overlap and others where the kickstand is located within a hollow area of the rotating device.

II. Prior Art Landscape

The field of puzzle accessories is crowded with products that aim to enhance the user experience by providing dedicated surfaces, sorting capabilities, and ergonomic adjustments. A review of the prior art available before the earliest priority date of the '430 patent (September 26, 2021) reveals that puzzle boards incorporating features such as drawers, tilting mechanisms, and rotating bases were well-known.

Publicly available information, including product listings on retail websites and video reviews, constitutes valid prior art. Numerous commercially available products combine these functionalities. For example, products described as "2-in-1 Tilting and Rotating Puzzle Board" with drawers are readily found. These products often feature a Lazy Susan for rotation and a separate mechanism for tilting.

III. Obviousness Analysis

Under 35 U.S.C. § 103, an invention is unpatentable if the differences between the claimed invention and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art. The '430 patent's claims appear vulnerable to an obviousness rejection based on a combination of existing prior art elements.

Combination of Prior Art:

A person of ordinary skill in the art (POSITA), such as a puzzle accessory designer or an avid puzzler, would be motivated to combine elements from known puzzle boards to create the apparatus claimed in the '430 patent. The primary motivation would be to improve user convenience and ergonomics, addressing the known challenges of working on large puzzles as described in the "Background of the Present Invention" section of the '430 patent itself.

Argument for Motivation to Combine:

1. Reference A: Puzzle Board with Drawers and a Rotating Device (e.g., a Lazy Susan). Products like the "Jumbl 1500-Piece Puzzle Board with Drawers - Lazy Susan and Cover" were commercially available. These products teach the utility of a rotating base for accessing all parts of a large puzzle without the user having to move, combined with drawers for sorting pieces.

2. Reference B: Tilting Puzzle Board or Easel. The concept of a tilting surface for artwork, drafting, and puzzles is long-established. Products specifically marketed as "Tilting Puzzle Table" or boards with an "Adjustable Tilting" feature were also common. These address the ergonomic problem of hunching over a flat table, a problem explicitly mentioned in product reviews and descriptions.

A POSITA, aware of the distinct advantages of both rotating boards (Reference A) and tilting boards (Reference B), would find it obvious to combine these features to create a single, more versatile product. The goal would be to provide the user with the option of either rotating the puzzle on a flat surface or tilting it for comfortable, prolonged use. This combination directly addresses the market demand for more ergonomic and convenient puzzle accessories. Products explicitly marketed as "2-in-1 Rotating Tilted Jigsaw Puzzle Board" demonstrate that this combination was not only conceivable but was actively being produced and sold.

Mapping Claims to Prior Art Combination:

• Puzzle board with puzzle plate and drawers: This is explicitly taught by Reference A and is a common feature in many puzzle boards.
• Rotating device: Taught by Reference A, typically a Lazy Susan mechanism.
• Kickstand (or tilting mechanism): Taught by Reference B. While the '430 patent uses the term "kickstand," the function is identical to the tilting stands and easels found in the prior art. These mechanisms, by their nature, are in a "non-working state" when the board is laid flat for rotation.

The specific arrangement where the kickstand and rotating device are "spaced apart" as claimed in the '430 patent is a natural and necessary consequence of combining these two known elements. To allow for both tilting and rotation, the mechanisms for each function must be designed so as not to interfere with one another. A designer would intuitively place a kickstand or easel support in a location that allows the Lazy Susan to function when the board is flat, and vice-versa. The claim language describing one feature being in a "non-working state" while the other is in use is merely a description of the operation of this obvious combination.

IV. Conclusion

The claims of US Patent 12,491,430 appear to be obvious under 35 U.S.C. § 103. The invention combines known elements from the prior art—a rotating puzzle board with drawers and a tilting mechanism—in a predictable manner. A person of ordinary skill in the art would have been motivated to combine these elements to create a more ergonomic and versatile puzzle platform. The resulting combination would render the claims of the '430 patent obvious, as the claimed features and their operation are directly taught or suggested by the prior art. Numerous commercially available products that predate the patent's priority date embody this very combination of features.
