Latest Patents

One of his latest patents is titled "Cutting elements having non-planar surfaces and downhole cutting tools using such cutting elements." This invention features a cutting element that includes a substrate and an ultrahard layer. The top surface of the ultrahard layer has a peripheral edge surrounding the cutting element, a cutting crest that extends across a major dimension from a cutting edge to a modified region at the central axis, and a lateral portion that spans a minor dimension from the peripheral edge to the modified region. The modified region along the major dimension has a concave cross-sectional shape, while the lateral portion can have a linear or convex shape. Additionally, the modified region along the minor dimension is planar and perpendicular to the central axis.

Another notable patent is "Thermally stable polycrystalline diamond and methods of making the same." This method involves creating a cutting element by subjecting a mixture of diamond particles and a carbonate material to high-pressure, high-temperature sintering conditions. The result is a sintered carbonate-polycrystalline diamond body with a diamond matrix of bonded diamond grains and carbonates in the interstitial regions. The carbonate material is then subjected to controlled temperature and pressure conditions to achieve partial decomposition.
