Listen as Husch Blackwell partners Rudy Telscher and Dan Cohn discuss the ins and outs of IPRs.…
In Part 1, we addressed the pros and cons of molding your mark directly into your goods in the context of 3D printing. In Part 2 of this series, we evaluated potential benefits and pitfalls that businesses may encounter when applying a mark to products at a later stage in manufacturing (e.g., via sticker or ink-printing). Here, we will look at two counterfeiting scenarios: Case 1, in which your mark has been molded or…
In Part 1 of this series, we addressed the impact of 3D printing on companies that mold their marks directly into their goods. Now, in Part 2, we will evaluate potential benefits and pitfalls that businesses may encounter when applying a mark to products at a later stage in manufacturing (e.g., via sticker or ink-printing). Many companies decide not to mold or 3D print their marks directly into their product. Such a decision may be…

If a direct competitor has begun printing a…
At a high level, creating a 3D printed product involves several steps. First, the product itself is conceived. Next, the product is designed in a computer aided design program, and must be converted into a set of electronic instructions that tell the 3D printer how to create the product. In some instances, the CAD program itself may create the printer instructions. The last step is the actual printing of the product. Not all businesses can…
In this three-part series, we will discuss various copyright issues that may arise from 3D printing. The first two posts in the series will address copyright issues for companies that are just beginning to utilize (or are thinking about utilizing) 3D printing. The final post in this series, however, will address a company’s reactions to other 3D printers who create potentially infringing products. In this post specifically, we will address some basic copyright pitfalls of…
