Aug 21 (Reuters) - A Delaware federal jury determined on Friday that Cytek Biosciences' CTKB.O products for analyzing single-cell blood and tissue samples infringe a patent owned by rival Beckman Coulter.
The jury agreed with Danaher-owned DHR.N Beckman that Cytek's Aurora flow cytometers and other products violate Beckman's patent rights in technology used in its competing CytoFLEX platform.
The jury said that Cytek owed Beckman $36 million in royalties and $20 million in lost profits.
Spokespeople for the companies did not immediately respond to requests for comment on the verdict.
Beckman first sued Cytek over the patents in 2024.
Cytek denied the allegations and argued the patents were invalid.
The jury found on Thursday that Cytek did not infringe two of the three patents at issue in the trial and that those two patents were invalid.
California-based Cytek earned $201.5 million from overall sales of its products last year, according to a company report.
