CAO Group files Patent Infringement Complaint Against P&G's CREST® Whitestrip Products


This is an interesting bit of news.  Densen Cao, PhD is the CEO of CAO Group, Inc and, in my opinion, he is 'renaissance thinker'.  He has over 100 patents and is responsible for some of the best technologies in dentistry and consumer goods.  Dr. Cao is the inventor of the dental LED curing light and also invented the LED light bulb that has practically replaced the older incandescent technology.  His company sells quite a few high tech devices in the dental space.

One of the products sold by CAO Group is called Sheer White and it is a strip that is placed over the teeth.  It contains chemicals that whiten enamel.  Proctor & Gamble is a corporate giant that owns several subsidiaries, one of which is Crest.  They sell a similar product called Crest White Strips which is a direct competitor to Sheer White.

Now comes word that CAO has filed a patent infringement complaint against Proctor & Gamble.  The press release is below:

The CAO Group, Inc. (CAO), a world leading high-technology 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 their Crest® teeth whitening strip products infringe claims of CAO's U.S. patents 10,603,259 and 10,646,419.  CAO is represented by the law firm of Skiermont Derby LLP.

Teeth whitening is one of the most requested procedures in both professional dental practices and consumer cosmetics. Whitening strips are the most advanced teeth whitening method and are preferred over other whitening methods such as gel/tray, whitening pen, rinse, and toothpaste, as evidenced by the wide adoption of whitening strips in the U.S. market.  CAO has devoted its research, development, and manufacturing efforts over the last 15 years to improve whitening strip technology to make teeth whitening 'Easier, Faster, and Better' for dental professionals and consumers.  The innovations in teeth whitening strips by CAO include a new thickener for peroxide, flexible substrate materials, and a gelatinous formulation.  Particularly, 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.  The innovations enable users to wear the teeth whitening strips without annoyance and with better whitening results.


"Our improved whitening strip technology is loved by consumers and is also adopted by marketers in the U.S. market," said Dr. Densen Cao, PhD, CEO and founder of CAO. "We will fiercely defend our intellectual properties against infringers."

CAO's SheerWhite® whitening strips powered by these invented technologies are the leading whitening products within the professional market to serve dental practices and their customers. The SheerWhite whitening system offers both In-Office and Take-Home whitening strips to enable dental practices to conduct the whitening procedures Easier, Faster, and Better.
