# Cytek owes Beckman Coulter $56 mln in cell-analysis patent case, US jury says

By Blake Brittain

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.
