USPTO Patent Grant for Triply Periodic Minimal Surface Implants
Summary
The USPTO has granted a patent to RESTOR3D, INC. for sheet-based triply periodic minimal surface (TPMS) implants designed to promote osseointegration. The patent covers novel gyroid architectures and selective laser melting techniques for improved mechanical performance and reduced defect formation in implants.
What changed
The United States Patent and Trademark Office (USPTO) has granted patent US12582527B1 for sheet-based triply periodic minimal surface (TPMS) implants and their production methods. The patent, assigned to RESTOR3D, INC., details implants featuring gyroid architectures that enhance osseointegration and mechanical performance, with anisotropic mechanical properties along the insertion direction. Novel selective laser melting (SLM) techniques are also described to minimize defects and improve implant properties.
This patent grant signifies the issuance of intellectual property for a new type of medical implant technology. While not a regulatory rule imposing obligations, it impacts the landscape for medical device manufacturers in the field of orthopedic implants. Companies developing or manufacturing similar implants should be aware of this granted patent and its claims, particularly concerning the TPMS gyroid architecture and SLM manufacturing processes, to ensure freedom to operate and avoid potential infringement.

Abstract
Provided herein are implants and methods for producing implants. In at least one embodiment, the implants include sheet-based, triply periodic, minimal surface (TPMS) portions. According to one embodiment, the TPMS portions include a gyroid architecture that provides for improved osseointegration and mechanical performance over previous implants due to novel ratios of porosity to compressive strength, among other features. In one or more embodiments, the gyroid architecture is organized into unit cells that demonstrate anisotropic mechanical performance along an insertion direction. In various embodiments, the present methods include novel selective laser melting (SLM) techniques for forming the TPMS portions of implants in a manner that reduces defect formation, thereby improving compressive performance and other implant properties.
