In Brief: Pall v. Hemasure

This article was originally published in The Gray Sheet

Executive Summary

Pall v. Hemasure: Pall files suit alleging that Hemasure's LeukoNet leukocyte removal device for filtering donated blood infringes upon Pall patents covering "the processing of blood or blood products." LeukoNet was cleared by FDA in June 1995 ("The Gray Sheet" Jan. 9, 1995, In Brief). The suit, filed in the U.S. District Court for the Eastern District of New York, seeks an injunction against Hemasure as well as damages. Hemasure says it does not believe LeukoNet infringes "any valid patent rights." Separately, Hemasure announces that it has entered into a collaborative agreement with the Pacific Northwest Regional Blood Services of the American Red Cross, Portland, Oregon, to study the effectiveness of using LeukoNet technology "to remove tumor cells from peripheral stem cell concentrates which are used in certain cancer therapies"...
