Péter Szegõ 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).

  • Patent number: 9839607
    Abstract: The invention concerns a pH-dependent gradual sustained release composition for increasing the pH in the upper part of the small intestines. Particles of the composition are provided with a multilayer polymer coating of specific structure which ensures the gradual release of the active agent in the range of pH 4.5 to 5.5. A process for preparing said composition is also claimed.
    Type: Grant
    Filed: May 12, 2011
    Date of Patent: December 12, 2017

  • Patent number: 7090846
    Abstract: Polycation bioconjugates and a method for producing them. The polycations are capable of transporting active substances of different types. The polycations function as carrier molecules that transport enhancer molecules, thereby enhancing the biological effectiveness of the transported molecules. The polycation bioconjugates of the present invention may inhibit malignant cell proliferation, possess antimicrobial effect, or be configured for gene transport.

  • Patent number: 4686986
    Abstract: A method and apparatus for the stimulation of biological processes related to cellular activity, particularly for promoting the healing of lesions on the body-surface, i.e. wounds, ulcers and epithelial injuries.The lesion is irradiated with linearly polarized light of predetermined intensity, comprising incoherent components of wavelength, exceeding 300 nm.The apparatus comprises a light source, constituted by a lamp emitting incoherent visible and/or infrared light, a deflecting system projecting the light beams into the given direction of treatment, a polarizer placed in the path of the light beam, projected into the direction of treatment, and preferably ultraviolet and infrared filters.
