Tatcha, LLC

Tatcha, LLC is a San Francisco-based luxury skincare company founded by Victoria Tsai in 2009. The company operates as a subsidiary of the global consumer goods corporation Unilever, which acquired it in June 2019 for a reported sum approaching $500 million. While revenue figures are not officially disclosed, reports at the time of its acquisition stated the brand was on track to achieve $100 million in net sales for 2019. Employee counts are estimated to be in the range of 100-300 people.

Tatcha is an operating company that develops, markets, and sells a range of high-end skincare products inspired by classical Japanese beauty rituals. Its product lines include moisturizers, cleansers, exfoliators, serums, masks, and sunscreens, which are sold through its own e-commerce website and high-end retailers such as Sephora. The brand's formulations often feature a signature complex of green tea, rice, and algae called Hadasei-3.

As a patent litigant, Tatcha appears as an operating company taking a proactive defensive stance against a non-practicing entity (NPE). The company has been tracked in one case as a plaintiff and has no recorded cases as a defendant. This posture suggests the company is not a target of frequent litigation but has used the court system to challenge a patent assertion.

The company's single tracked case is a lawsuit it filed, Tatcha, LLC v. Landmark Technology, LLC. The defendant, Landmark Technology, and its successor entities have been widely described as a "patent troll" or patent assertion entity. Landmark has a history of sending thousands of demand letters to businesses, asserting a patent related to common e-commerce website features and demanding licensing fees. Tatcha's filing of a suit against such an entity is characteristic of a declaratory judgment action, where a company that has been threatened asks a court for a ruling of non-infringement or patent invalidity.
