CAO Group Files Patent Infringement Complaint against P&G’s Crest Whitestrip Products

Salt Lake City, UT company files suit in Central District of California.

The CAO Group, Inc., a Salt Lake City, UT-based dental company, has filed a complaint with the United States District Court for the Central District of California against The Procter & Gamble Company and The Procter & Gamble Distributing LLC, declaring that Crest teeth whitening strip products infringe claims of CAO's US patents (10,603,259 and 10,646,419). 

CAO offers SheerWhite whitening strips in the professional market to serve dental practices and their customers. The brand includes in-office and take-home whitening strips.

CAO says its innovations in its teeth whitening strips include a new thickener for peroxide, flexible substrate materials, and a gelatinous formulation. The gelatinous formulation provides a gelatin layer on the strip with adhesive properties to attach to the teeth when the strip touches the tooth surfaces.

Dr. Densen Cao, PhD, CEO and founder of CAO, said the company “will fiercely defend our intellectual properties against infringers.”

The global oral hygiene market will exceed $70 billion by 2031.

Crest launched its Whitestrips line in 2001.
