We are looking to get a trademark under the name "3DPCB" for our machine. Based on available information, "3DPCB" is likely not a widely registered trademark, but it could potentially be trademarked by a specific company depending on their usage and registration status; "3D" refers to a three-dimensional design, while "PCB" stands for "printed circuit board," so the combination could be considered a descriptive term for a type of printed circuit board, making it harder to trademark broadly.
According to the U.S. Copyright Office, there are no outstanding Copyrights on Mobile / At-Home printed circuit board (PCB) Printers. There are only copyrights on methodologies for certain designs and printing techniques, though not ones that our product will be using.

Voltera Inc. is a PCB manufacturing company that owns four patents relating to what we aim to do with our project. While these patents are similar, the nature of their products is fundamentally different as they print/engrave circuit traces on premade substrate boards. We plan on printing everything from scratch, including the physical boards and the conductive material, resulting in a fully finished board.
