Tantech Holdings shares surge 22.39% premarket after U.S. subsidiary receives USPTO trademark allowance for "TANHOME" brand expansion.

Tantech Holdings surged 22.39% in premarket trading following the announcement that its U.S. subsidiary, Tanhome Group Inc., received a Notice of Allowance (NOA) from the U.S. Patent and Trademark Office for the "TANHOME" trademark. The approval, a critical step in the company’s brand protection strategy, grants commercial rights across key segments of its "Green Home Ecosystem," including flooring, cabinets, and retail services. CEO Zheyuan Liu emphasized the milestone’s role in fortifying the brand’s legal compliance and credibility as a one-stop eco-friendly building materials provider in North America. The news aligns with Tantech’s 2022 U.S. subsidiary expansion and 2024 entry into the home building materials industry, signaling progress in its North American growth ambitions. The trademark’s registration process now requires a 'Statement of Use' filing within six months, reinforcing investor confidence in the company’s intellectual property and long-term strategic positioning.
