1 case as defendant.
TUOZHU TECHNOLOGY LIMITED, along with its operating entity SHENZHEN TUOZHU TECHNOLOGY CO., LTD., is a private technology company headquartered in Hong Kong and Shenzhen, Guangdong, China, respectively. Shenzhen Tuozhu Technology Co., Ltd. was established in 2020 and is reported to employ over 1,000 people.
The company operates primarily under its "Bambu Lab" brand, focusing on the development and sale of desktop 3D printers, 3D printer filaments, automatic feeding systems, and various accessories for personal, commercial, and educational use. Their product offerings include series such as the X1 and A1.
TUOZHU TECHNOLOGY LIMITED is an active two-way litigant in the patent arena, with a current posture involving both defense and assertion. It has been named as a defendant in one case brought by Stratasys, Inc. in the U.S. District Court for the Eastern District of Texas, a venue known for its plaintiff-friendly docket. Concurrently, the company has initiated two plaintiff cases against Stratasys, Inc. at the Patent Trial and Appeal Board (PTAB) of the USPTO, likely seeking to challenge the validity of patents asserted against them.
All tracked cases involve Stratasys, Inc., highlighting a focused dispute within the 3D printing sector. This litigation includes claims by Stratasys of infringement relating to 3D printer technology, such as heated build platforms. Shenzhen Tuozhu Technology Co., Ltd. has also recently patented new 3D printer heatbed designs, which may play a role in this ongoing legal context.
Stratasys filed this patent infringement lawsuit in August 2024 against Bambu Lab and related entities. Prior to its consolidation into case 2:25-cv-00465-JRG in June 2025, a motion to dismiss by Bambu Lab was denied on May 29, 2025.
