The Gillette Company – owned by the Procter & Gamble Company – filed a patent infringement lawsuit this week. The case was filed in the U.S. District Court of Connecticut against Edgewell Personal Case and some of its subsidiaries.

The lawsuit challenges Edgewell’s Hydro Connect 5 razor cartridges, which are sold online and positioned as compatible with Gillette Fusion handles. The lawsuit alleges patent infringement and seeks damages from these infringements. P&G also filed a complaint with the U.S. International Trade Commission (ITC) seeking an exclusion order to prohibit Edgewell from importing the products into the United States from China.

The patent in question is found in the Gillette Fusion Family, one of the most advanced, popular razor families in the world. The patent, which relates to how the razor cartridge and handle connect, was granted to P&G in 2015. The lawsuit alleges that Edgewell violates this patent with two products, Hydro Connect 5 and Hydro Connect 5 Sensitive, which were launched in May of this year.

Gillette has been a leader in the grooming industry for over 100 years so it regularly patents its breakthrough inventions, which are developed through strong consumer understanding and technological expertise. The company also invests heavily in research and development to stay at the forefront of shaving technology and to deliver an incredible shaving experience for men around the world.

“For over a century, Gillette has been investing to deliver world-class innovation and shaving products of the highest quality, which is why so many men trust their faces to Gillette,” said Chief Legal Officer Deborah P. Majoras. “It is also why we take action when necessary to defend our vital technical advancements and the equally vital scientists who produce them.”
