Desktop Metal, the metal 3D printing technology startup with a value of more than $1 billion, has filed a lawsuit against Markforged, Inc.
The claims are related to alleged patent infringement, “trade secret misappropriation,” breach of contract and unfair trade practice, for a total of two “Patents in Suit.”
The Patents in Suit
The Patents in Suit are stated in the official case filing as, “Fabricating Multi-Part Assemblies” (U.S. Patent number 9815118) known as the ‘118 patent, and “Fabricating an Interface Layer for Removable Support” (Patent number: 9833839) referred to as the ‘839 patent.
The ‘118 patent relates to Desktop Metal’s additive manufacturing process – a part is printed, then sintered, it shrinks, and the parts can be removed from supports by hand.
The ‘839 patent on the other hand specifically relates the company’s no-fuss method of post-processing – it’s “secret ingredient” if you will. It details the concept of jetting a sacrificial layer between a 3D printed part and support material, that burns away during the sintering process.
The history of interaction between Desktop Metal and Markforged
Now, the history of interaction between Desktop Metal and Markforged gets quite complicated.
Desktop Metal was founded in 2015 by Ric Fulop, the company’s CEO, and a number of researchers from MIT. The company’s CTO, Jonah Myerberg, is also a founding member.
Prior to founding Desktop Metal, Fulop was a General Partner of venture capital fund North Bridge, that was an early investor of a number of 3D technology companies including, Onshape CAD software, Dyn (since acquired by Oracle cloud computing) and Markforged.
When Fulop expressed his intentions to start a new company, he left the board at Markforged and enlisted a third party, the CEO of Onshape and Markforged advisor to review his plans for Desktop Metal and determine any IP infringments. As the Case Filing states “No issues were raised to Mr. Fulop”.
In 2016, Desktop Metal hired Matiu Parangi as a technician for the company’s developing print farm.
In this time, Desktop Metal claims that Parangi downloaded proprietary information unrelated to his role as a technician. The company then went on to discover that Parangi is the brother of Abraham Parangi, Director of Technology & Creative at Markforged.
“Shortly afterwards,” as the filing states “in January 2017, Markforged announced its Metal X printer for 3D printing metal at CES 2017.” And Desktop Metal finds that there is a crossover in the two 3D printing approaches.
Desktop Metal’s claim
The Metal X 3D printer uses metal injection molding (MIM) powder as a primary feedstock. Secondly, supports on the Metal X are easily removed thanks to a layer of ceramic ink that burns out in the sintering process.
The claim, therefore, is “As Desktop Metal begins shipping its Studio System, Markforged is seeking to compete directly with Desktop Metal by offering its Metal X 3D print system.”
“Based on at least Markforged’s recent disclosures that its Metal X 3D print system uses a ceramic release layer that turns to powder during sintering, Markforged seeks to compete using Desktop Metal’s patented technology protected by the Patents-in-Suit.”
Further details about the exact nature of the infringement are given in support.
Desktop Metal has requested a Jury Trial for the case, and has made a total of 16 requests for how the court should take action.
To summarize, Desktop Metal hopes the jury will find in favour of all complaints and requests that an injunction is put in place to stop Markforged plus related parties from further infringement on its IP.
Further, the company requests monetary damage compensation from Markforged, “An award of three times Desktop Metal’s actual damages for Markforged’s unfair
trade practices,” “Civil seizure of property incorporating Desktop Metal’s trade secrets,” and any such “further relief” as the Court deems just.
At present, neither company have released statements about the alleged claims. 3D Printing Industry however, will be staying abreast of any further developments in this case and inform our readers of its progress and outcome.
