Afinia Responds to Stratasys: Patents Invalid… Threats Anticompetitive… #3DThursday #3DPrinting #3D

In an interesting turn of events in the desktop 3D printer patents questions coming up lately, Afinia did not back down when faced with a lawsuit from 3D industry giant Stratasys. Michael Weinberg from Public Knowledge examines the counters suit in detail in his post “Afinia Responds to Stratasys: Your Patents Are Invalid and Your Threats Are Anticompetitive.”

Here’s a brief note and excerpt from his analysis:

…As with Stratasys’ complaint, it is important to include a quick caveat when thinking about Afinia’s response.  Afinia’s response is written by Afinia’s attorneys and is designed to present all of the facts in a light as beneficial to Afinia as possible.  That doesn’t mean that there is anything untrue in the response, but it does mean that any claims made in the response should be taken with a grain of salt.  That being said, as with the earlier analysis of the Stratasys complaint, in an attempt to explain what is going on this post will more or less take Afinia’s claims at face value.

Afinia’s Response

The short version is that Afinia challenges the validity of all four of the patents that Stratasys accuses them of infringing.  This goes beyond simply asking the court to decide that Afinia does not infringe on any of the Stratasys patents (although Afinia does do that).  Afinia is also asking the court to find Stratasys’ patents totally invalid, which would prevent Stratasys from asserting them against anyone else.  In light of Afinia’s belief that Stratasys’ patents are invalid, Afinia also accuses Stratasys of using this lawsuit and its patents to try and monopolize the 3D printing market….

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
