There has been much speculation about the impact of 3D printing on the enforcement of IP rights. But very few decisions. Now, finally, a case you can sink your teeth into: ClearCorrect v. ITC, 2014-1527 deals squarely with a patent infringement allegation which focuses on 3D-printing technology.
This case relates to the production of orthodontic appliances known as teeth aligners. According to patents owned by Align Technology, their aligners "are configured to be placed successively on the patient's teeth and to incrementally reposition the teeth from an initial tooth arrangement, through a plurality of intermediate tooth arrangements, and to a final tooth arrangement..." as listed in the '880 patent. (As soon as you see the word "plurality", you just know you're reading a good patent.)
ClearCorrect, a competitor of Align Technology, produced aligners by means of 3D-printed digital models of aligners. ClearCorrect electronically transmitted digital files to its subsidiary ClearCorrect Pakistan (thus skirting the US patent rights) where digital models of the aligners were created and configured. ClearCorrect Pakistan then electronically transmitted these digital models back to ClearCorrect US, where the digital models were 3D-printed into physical models. From there, aligners were manufactured using the physical models.
The patent owner alleged that the transmission of these digital three-dimensional models should be stopped at the border, just like any infringing "article" would be stopped. Typically, an owner of US patent rights can employ the resources of the ITC to stop and seize articles - take for example, a piece of equipment or a consumer product - which infringes a US patent. This prevents the infringing articles from being imported into the US, even if they are manufactured overseas. In this case, the court had to decide if digital three-dimensional files constituted "articles" for these purposes.
In the end, the court considered articles to be "material things" and decided that the 3D-printable digital files were not "articles". Thus, the ITC lacked jurisdiction to prevent the entry of these files into the US. (Exactly how it could prevent the transmission of the files is another matter entirely.)
Something to chew on while we wait to see if the decision will be appealed.
