NanoString Will Immediately Appeal Preliminary Injunction Temporarily Blocking NanoString’s Ability to Market and Sell CosMx Spatial Molecular Imager Products for RNA Detection within UPC Member Countries in Europe

NanoString Technologies, Inc. (NASDAQ: NSTG), a leading provider of life science tools for discovery and translational research, commented on today’s order from the European Unified Patent Court (UPC) granting a preliminary injunction effective immediately in 17 Member States of the European Union against NanoString’s CosMx™ Spatial Molecular Imager (SMI) products for RNA detection in NanoString’s ongoing patent dispute with 10x Genomics and Harvard:

“We are disappointed with today’s decision by the UPC and will immediately appeal the preliminary injunction in the UPC Court of Appeal in Luxembourg. We are confident in our belief that we do not infringe the asserted patents, and that the patents will ultimately be found to be invalid. We also respectfully believe the court erred by failing to adequately consider evidence demonstrating that the patents asserted by 10x were funded by a grant of over $19 million from the National Institutes of Health that required open and non-exclusive licensing to promote the public interest.

NanoString remains steadfast in our commitment to defend the scientific community’s access to our products and researchers’ scientific freedom to select the platforms that best advance their research. Importantly, today’s ruling does not impact NanoString’s legal ability to market or sell CosMx SMI products for protein detection in the European Union, nor does it impact the lawful selling of any NanoString CosMx SMI products in the United States, the United Kingdom or the rest of the world outside of the EU member states participating in the UPC system.

We believe that 10x Genomics has resorted to the courts and is misusing non-final court rulings as part of its commercial strategy to eliminate competition in the spatial transcriptomics market to the detriment of the public good. NanoString provides the scientific community with highly differentiated spatial biology tools with capabilities for both spatial transcriptomics and spatial proteomics that exceed those of any other spatial analysis systems. We are proud of the role our CosMx SMI products serve in helping the scientific community to better understand the genome and its functions and ultimately drive breakthrough scientific discoveries that produce lifesaving medical benefits for patients around the world.

NanoString is committed to defending a competitive, innovative marketplace. We will immediately appeal the decision to the UPC Court of Appeal in Luxembourg. We look forward to presenting multiple arguments to invalidate the asserted patents and demonstrate our non-infringement of these patents at the full UPC hearings on the merits of our case. We do not yet have a date for those hearings.”

Brad Gray, President and CEO, NanoString Technologies, Inc.

Today’s order relates to European Patent 4108782B1 (the “‘782 Patent”). The UPC announced that it would issue a decision in the preliminary injunction matter related to European Patent 2794928B1 (the “‘928 Patent”) on Tuesday, October 10, 2023.

As of August 31, 2023, NanoString currently estimates that less than 10% of the CosMx instruments orders in backlog are for the EU countries directly impacted by this decision. NanoString management is reiterating its guidance for fiscal year 2023 total revenue of between $175 -$185 million.
