EFF challenges bogus 3D printing patents

Earlier this month, the Electronic Frontier Foundation asked the US Patent and Trademark Office to turn down six broad, bogus patents on 3D printing that could pave the way for even more patent-trolling on the emerging field of 3D printing. They worked with the Cyberlaw Clinic at Harvard’s Berkman Center for Internet and Society and Ask Patents, as well as with its own supporters to gather evidence on the prior art that invalidates these applications. It's part of a larger project to systematically challenge patents in emerging fields -- next up is mesh networks -- providing a layer of vigilance and common sense atop the reckless and indifferent patent office.

Here are copies of what we submitted to the Patent Office. The good news is that so far, the Patent Office has accepted our submissions (because of that, if you're thinking of making your own preissuance submissions, you might want to use these as a model). Now we wait to see whether our input influences the examiners.

* Fabrication of Non-Homogeneous Articles Via Additive Manufacturing Using Three-Dimensional Voxel-Based Models

* Build Materials and Applications Thereof

* Method for Generating and Building Support Structures With Deposition-Based Digital Manufacturing Systems

* Process for Producing Three-Dimensionally Shaped Object and Device for Producing Same (Ask Patents request for prior art)

* Additive Manufacturing System and Method for Printing Customized Chocolate Confections (Ask Patents request for prior art)

* Ribbon Filament and Assembly for Use in Extrusion-based Digital Manufacturing Systems (Ask Patents request for prior art)

Our work doesn’t stop here. Next we’re going to investigate a number of pending applications that impact mesh networking technology—another area with an extremely active open development community and with tremendous potential. We’ll be asking you to help us again soon. Stay tuned!

Just one more way that EFF is making the future a better one.
