STRATASYS SUCCESSFULLY DEFENDS VALIDITY OF FDM PATENTS

U.S. Patent Trial and Appeal Board denies Afinia’s attempts to challenge validity of Stratasys IP

Minneapolis & Rehovot, Israel - June 12, 2015 - Stratasys Ltd. (Nasdaq:SSYS), a leading global provider of 3D printing and additive manufacturing solutions, announced that the U.S. Patent Trial and Appeal Board (PTAB) of the United States Patent & Trademark Office (USPTO) has denied Afinia's requests for inter partes review of three important FDM technology patents directed to liquefier structure, temperature control, and tool paths for constructing part perimeters.


Inter partes review is a proceeding in which the PTAB reviews the validity of claims in a patent. In denying Afinia's requests, the PTAB reasoned that Afinia "has not demonstrated a reasonable likelihood of prevailing," with respect to any of the challenged claims, in the Stratasys patents. This decision is particularly notable in that, based on current PTAB statistics (published by the USPTO), the PTAB denies only about one of four inter partes review requests.

"We are very pleased with the U.S. Patent Trial and Appeal Board's decision," said Soonhee Jang, Stratasys Vice President and Chief IP Counsel. "These dismissals are evidence of the strength of our patent portfolio."

These same three patents are asserted by Stratasys in the case of Stratasys, Inc. v. Microboards Technology, LLC dba Afinia, pending in the United States District Court for the District of Minnesota where Stratasys continues to pursue a relief from the court involving Afinia's infringement on three Stratasys patents.

Stratasys Inc.'s co-founder and chief innovation officer, Scott Crump, invented Fused Deposition Modeling (FDM), a technology that prints three dimensional objects from computer models by building them up in layers. Stratasys FDM solutions are the most widely adopted 3D printing solutions in the industry. The company will continue to significantly invest in technology, product and solution development, in order to make 3D printing more accessible and widely adopted by current and future users.

ST Robotics Develops the Workspace Sentry for Collaborative Robotics

The ST Robotics Workspace Sentry robot and area safety system are based on a small module that sends an infrared beam across the workspace. If the user puts his hand (or any other object) in the workspace, the robot stops using programmable emergency deceleration. Each module has three beams at different angles and the distance a beam reaches is adjustable. Two or more modules can be daisy chained to watch a wider area. "A robot that is tuned to stop on impact may not be safe. Robots where the trip torque can be set at low thresholds are too slow for any practical industrial application. The best system is where the work area has proximity detectors so the robot stops before impact and that is the approach ST Robotics has taken," states President and CEO of ST Robotics David Sands.
