This case involves a large corporation, based in Idaho, that patented a design for a home-use 3D printer. The plaintiff’s printer allowed individuals to produce small, 3D objects from smaller space and had rapid prototyping capabilities. It also worked in conjunction with a number of design programs, allowing individuals to share designs that could be printed. The company filed for, and received, a patent for the design. About a month later, the defendant finished producing a similar, home-use printer. The second company began selling their printers to consumers and marketing it in a similar manner. The plaintiff discovered the defendant’s actions and sued for patent infringement. An expert in intellectual property (IP) was sought to opine on the issue.
