Sysmex Sues Beckman Coulter for Patent Infringement

The story has been updated to include a comment from Beckman Coulter. 

NEW YORK (360Dx) – Sysmex has sued Beckman Coulter accusing it of infringing a patent covering a sample analyzer and a computer program.

The lawsuit, filed on Tuesday in US District Court for the District of Delaware, alleges Beckman Coulter infringes US Patent No. 10,151,746. According to documents filed with the US Patent and Trademark Office, the patent, which was issued on Tuesday, covers a sample analyzer which prepares a sample of blood or other fluid, measures the sample, analyzes it and provides results from the analysis. The patent also covers a computer program product.

The inventors of the patent's technology are based in Japan and the patent was assigned to Sysmex.

According to a complaint, Sysmex alleges a number of Beckman Coulter analyzers infringe the '746 patent, including the UniCel DxH 600; UniCel DxH 800; UniCel DxH 801; UniCel DxH 1600; UniCel DxH 1601; UniCel DxH 2400; UniCel DxH 2401; UniCel DxH 900; UniCel DxH 900 SMS; UniCel DxH 900-2; UniCel DxH 900-2 SMS; UniCel DxH 900-3; and UniCel DxH 900-3 SMS systems.

Sysmex said that the Beckman Coulter systems infringe a total of 11 claims contained in the '746 patent.

Sysmex Corporation, headquartered in Japan, and Sysmex America, based in Lincolnshire, Illinois, are the plaintiffs in the case and are asking for damages of an unspecified amount, as well as an injunction against Beckman Coulter prohibiting it from making, using, selling or supplying the systems that allegedly infringe the '746 patent. Sysmex asks for a jury trial.

In a statement, a spokesperson for Beckman Coulter, a Danaher company, said "Although it is our policy to not comment on litigation, Beckman Coulter believes these allegations are meritless, and we will vigorously defend ourselves against these claims."
