Claire Bygott 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: 9358502
    Abstract: De-polluting, self-cleaning coating compositions are disclosed which comprise an organic binder having dispersed therein photocatalytic titanium dioxide particles substantially in anatase form which have an average crystallite size between about 1 nm and about 150 nm and which preferably have photocatalytic activity in the presence of visible light. Advantageously, the coatings of the invention do not require pre-activation to achieve high initial photocatalytic activity against pollutants in the air, such as NOx compounds.
    Type: Grant
    Filed: August 31, 2007
    Date of Patent: June 7, 2016
    Assignee: Cristal USA Inc.
    Inventors: Julie Elizabeth Maltby, Claire Bygott

  • Patent number: 7521039
    Abstract: The present invention is directed to photocatalytically active rutile titanium dioxide. The photocatalytically active rutile titanium dioxide of the present invention demonstrates enhanced activity in the visible light spectrum. It may be produced by neutralizing rutile seed to a higher pH than that at which it has traditionally been neutralized prior to washing and thermally treating the seed.
