Patent and litigation trends for 3D printing technologies

The success story of 3D printing began in 1984 when Charles W Hull applied for a patent for stereolithography. In 1989 S Scott Crump of Stratasys invented fused deposition modelling, which fuses material layer by layer until a 3D object is created. This style of additive manufacturing is what most people associate with 3D printing. In 2009 the patent for fused deposition modelling expired and companies started to take a different approach by trying to sell to consumers instead of business to business. Together with the rise of Kickstarter, a perfect storm formed and hype around 3D printing in the early 2010s was born. In order to identify 3D print-related patents, the IPlytics platform database performed an extensive keyword search of worldwide filed patents in the 3D-print technology field. The search was based on the patent’s content, making use of state-of-the-art stemming and semantic indexing methods. Between 2007 and […]
