Li-Lin Chen 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: 8188501
    Abstract: An optical device capable of emitting polarized light includes a light emitting means, two multi-layer optical films disposed above and below the light emitting means and two metal layers. The two metal layers cover the two multi-layer optical layers from the upper and lower sides respectively. Each of the two multi-layer optical films includes at least two films made from materials of different refractive indexes that are stacked in a staggered manner. The optical film formed by the multi-layer optical films and metal layers provides greater reflectance to S-polarized light (TE) and higher absorption to P-polarized light. Light generated by the light emitting means emits diagonally to the optical films and is reflected several times thereof to form S-polarized light (TE) to emit sideward.
    Type: Grant

  • Patent number: 5766871
    Abstract: A method of screening for a given enzyme in colony-forming cells using a substrate of the enzyme that has low solubility. Use of such a method leads to the discovery of glutaryl-7-aminocephalosporanic acid (GL-7-ACA) acylase of Pseudomonas nitroreducens. Also disclosed is a method of obtaining GL-7-ACA acylase from Pseudomonas cells.
