Timothy Clutterbuck has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Rotationally stabilized contact lenses
    Publication number: 20050237482
    Abstract: The invention provides a lens in which the lens periphery is controlled as to each of thickness differential and both the rate of change from thinner to thicker regions and the shape of the transition from thinner to thicker regions within each of the dual thin zones. The lens of the invention substantially reduces the time for the lens' auto-positioning. Additionally, the lenses of the invention maintain their on-eye orientation better as compared to conventionally stabilized lenses.
    Type: Application

  • Differential thickness contact lens with compensation for differential shrinkage and method of manufacturing same
    Patent number: 6234629
    Abstract: A contact lens and a method of manufacturing a contact lens having areas of different thickness, the contact lens being compensated for differential shrinkage during the manufacturing process. The unwanted toricity induced by the differential shrinkage caused by a particular manufacturing process is experimentally determined, both in terms of angular position and power. The lens compensation is achieved by providing an equal and opposite power to the unwanted toricity induced by the manufacturing process.

  • Differential thickness contact lens utilizing multiple base curves and method of manufacturing same
    Patent number: 5988813
    Abstract: A method of producing a compensated contact lens that is compensated for power deviation from target due to differential shrinkage, and also a compensated contact lens. The invention includes the steps of designing a lens to have first and second areas of different thickness and a cylinder axis having a predetermined angular position; determining a plurality of power correction factors, one for each of a plurality of cylinder axis ranges of the lens; and modifying the lens using a selected one of the plurality of power correction factors corresponding to the cylinder axis ranges of the lens containing the cylinder axis of the lens.
