Stuart Johnston 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).

  • Publication number: 20030049711
    Abstract: The instant invention provides nucleic acid molecules encoding insect 26/29 cysteine protease, as well as 26/29 cysteine protease encoded thereby. The invention further provides methods of identifying agents that modulate a level of 26/29 cysteine protease mRNA, polypeptide, or enzyme activity. Such agents are candidate insecticidal compounds.
    Type: Application
    Filed: June 26, 2002
    Publication date: March 13, 2003
    Inventors: Allen J. Ebens, Thomas J. Stout, Stuart Johnston, Dat Nguyen
  • Publication number: 20030027191
    Abstract: The instant invention provides nucleic acid molecules encoding insect ethanolamine kinase, as well as ethanolamine kinase encoded thereby. The invention further provides methods of identifying agents that modulate a level of ethanolamine kinase mRNA, polypeptide, or enzyme activity. Such agents are candidate insecticidal compounds.
    Type: Application

    Inventors: Allen J. Ebens, Stuart Johnston, Jean-Claude Breach
  • Publication number: 20030013177
    Abstract: The invention provides polynucleotides encoding insect glutaminyl cyclase, as well as polypeptides encoded thereby. The invention further provides host cells comprising expression vectors comprising polynucleotides of the invention. Isolated polypeptides and host cells of the invention are useful in methods of screening for agents that reduce glutaminyl cyclase activity. Such agents are useful as pesticides.

  • Patent number: 5898931
    Abstract: In a mobile communications system each radio unit (14, 16) is associated with a respective base station (12) as its `home` base station; any radio unit can communicate with any base station in whose service area it is located. Each base station has a radio interface (20) for communication with radio units, a telephone interface (24) for connection to a telephone line, for example via a PABX (44), and a LAN interface (28) for connection to a local area network (40) to which all the base stations are coupled. Voice communications for a handset are always routed through the home base station for that handset, e.g. to another handset or to the PABX, irrespective of the identity of the base station in whose service area the handset is currently located.
    Type: Grant
