Golf ball with wave-shaped dimple cross-sections
A multi-piece golf ball with many dimples whose cross-sections are wave-like curves of alternating projections and recesses relative to a reference circular arc through the dimple edges and deepest point. The design is intended for golfers seeking improved flight distance and aerodynamic performance. The dimples appear on the exterior cover of a conventional golf ball construction and are formed in the cover material by molding.
(57) What the patent covered
This write-up was generated by AI from the patent's text and may contain mistakes, so check it against the original patent before relying on it.
The main independent claim requires dimples whose curved-surface cross-section is a wave-like curve with one or more projections above and one or more recesses below a circular arc that passes through a dimple edge, the deepest dimple point, and the opposite edge, and where the distance from the dimple edge to the projection peak closest to that edge divided by the dimple radius is 20%–70%.
Distinguishing feature: Dimples use a specified wave-like cross-sectional profile with projections and recesses measured against a circular-arc baseline and a defined peak-to-edge ratio of 20%–70% of the dimple radius.
Novelty 3/5. The idea modifies conventional spherical dimples (common at filing) by adding multiple alternating peaks and troughs across the dimple depth rather than a simple spherical or conical depression.
Manufacturing
Molded cover with patterned mold cavities (steel mold inserts machined or EDM), core and cover assembly by compression or injection molding, finished by painting/marking; dimples formed during cover molding
Materials: Urethane or ionomer cover material (likely), rubber or resin core materials (likely), mold steel or plated mold inserts (for tooling).
Manufacturability 4/5. Requires precision mold cavities with wave-like dimple geometry (machining/EDM) and standard golf-ball molding and finishing; moderate part count and conventional assembly.

Before manufacturing
No related continuation or divisional patents in force were found. Design patents, trademarks and unrelated patents may still cover the product.
Claims are specific to a wave-like cross-sectional dimple profile and a 20%–70% peak-to-edge ratio; aerodynamic benefit depends on overall pattern, materials and manufacturing tolerances; patent has lapsed.
About 1.5% of lapsed patents are later revived by their owners. This page is a research lead, not legal advice. Obtain a freedom-to-operate opinion before manufacturing.
