Patent trolls may be preparing to target 3D printing

Patent trolls may be preparing to target 3D printing

With the number of 3D printing patents rising quickly, it's ripe for the next onslaught of litigation.

LONG BEACH, CALIF. -- While patent litigation has been on the rise for a number of years, it hasn't been between competing companies but from patent trolls who seek to buy up patent portfolios in order to sue industry players for infringement.

One of the fastest growing arenas for patents over the past decade has been 3D printing, making it a likely target for those trolls.

"For most trolls, the goal is not to actually go into litigation. The goal is to get a quick settlement," said Paven Malhotra, an intellectual property (IP) attorney with Keker & Van Nest LLP, whose clients include Intel, Comcast and Google and is based in San Francisco.

Malhotra, who spoke on IP rights at the RAPID 3D printing conference here, said since 2008 there have been 3,500 patents granted worldwide for 3D printing manufacturing methods. Over the last few years, 700 patent applications have been filed each year related to 3D printing.

"It generally takes two to three years before a patent is actually granted. While there has not necessarily been a lot of litigation so far, chances are that with the explosion in patents... the amount of litigation that will occur is going to increase dramatically," Malhotra said. "Especially if... trolls start going out and acquiring portfolios of patents related to 3D printing."

Some of the largest patent-filing areas in 3D printing recently have been related to tissue research and industrial processes.

Of the most recent and largest patent infringement lawsuits between competitors, all but one have been settled out of court. This includes litigation between 3D Systems and Formlabs, 3D Systems and Evision Tech, and Metris USA and Faro Technologies.

Infringement cases rarely make it before a judge mainly because the average cost of litigation ranges anywhere from $650,000 for patents worth under $1 million, to about $5 million for patents deemed to have a value of more than $25 million, Malhotra said.

Just the cost of filing for a patent is on average $22,000, and if granted, then companies must pay fees to maintain those patents that average $12,000 over the life of the intellectual property.

For many companies, especially start-ups, patents may prove cost prohibitive, so 3D tech developers need to look for alternative ways to secure their intellectual property, including selling licenses to use it.

One example of alternative route was when the Hasbro toy company became frustrated that consumers were downloading 3D-printable CAD files of its toys, such as My Little Pony or Transformers, from online sites including Shapeways and Thingaverse. Instead of suing the website owners, "Hasbro was forced to chase down these individuals to try to shut down the activty, which only alienated customers and was a lot of work for Hasbro," he said.

Instead of continuing to go after consumers or the websites hosting the printable files over patent infringement, Hasbro chose to offer its toy designs as licenses that could be purchased by consumers.

"Shapeways gets a cut, the designer gets a cut and Hasbro gets a cut," Malhotra said. "Perhaps we'll see more and more companies decide it's not worth it to try to chase down everybody to stop copyright infringement. There are actually alternative, innovative ways to make money and respect intellectual property at the same time."

Who owns 3D printed objects?

Alan Rothenbuecher, a partner at the law firm of Ice Miller LLP, agreed with Malhotra, saying if a company finds it too expensive to protect IP, it should sell it for use.

"Do what Microsoft does," Rothenbuecher said. "They give you a product key. They limit the number" of times it can be used, he said. "You're not registering [to use it] for the fun of it for your warranty. You're registering because they want to find out what you're doing with their products."

Yet another problem with IP law related to 3D printing is that once an object is printed it's not cut and dried who actually owns the rights to it, Rothenbuecher said. The conceptual artist who created the original design, the CAD file designer and the consumer who printed the object can all claim to have rights to the IP.

"The other difficulty that you'll have is that when somebody steals [your IP], there's an area in law right now where you either have to use, make or sell the product," Rothenbuecher said. "But if it's a digital file the law really hasn't caught up with that. So there's people making digital copies with the ability to circumvent the law."

Rothenbuecher said if IP is too expensive to protect, 3D innovators should take the Tesla approach -- innovating instead of patenting.

"By the time you catch up, they're already two generations ahead," he said.
