XVIVO Perfusion files lawsuit against Vivoline

XVIVO Perfusion is suing Vivoline to safeguard XVIVO Perfusion’s exclusive rights to Vivoline’s patents for three products invented by Professor Stig Steen.

XVIVO Perfusion AB (publ) has today initiated legal proceedings against Vivoline Medical in order to safeguard the exclusive global unlimited rights that XVIVO Perfusion AB (publ) has to certain media developed by Professor Stig Steen for the evaluation and preservation of organs in connection with transplantation.

XVIVO Perfusion’s own product STEEN Solution™ is not part of the dispute and is protected by a patent which has been granted and is valid until 2021.

Pursuant to the current agreement with Professor Stig Steen and Igelösa Life Science AB (which is the largest owner of Vivoline Medical), XVIVO Perfusion has global unlimited irrevocable exclusive rights to media and related patents for the preservation and evaluation of organs, media which are based on LPD (low potassium dextran), with added calcium, created by Professor Stig Steen.

A number of Vivoline Medical’s products and related patent rights are for media created by Professor Stig Steen for the preservation and evaluation of organs, media which are based on LPD with added calcium. One such patent thus covered by XVIVO Perfusion’s exclusive rights is the patent protecting Vivoline Medical’s planned product SS2, a solution for reconditioning and evaluating lungs before transplantation. Vivoline Medical’s products Heartadex 1 and 2 are protected by patents and patent applications that also are covered by XVIVO Perfusion’s rights, in accordance with the information given in Vivoline Medical’s memorandum from April 2013.

Magnus Nilsson, XVIVO Perfusion’s CEO states: “XVIVO Perfusion takes a serious view of this and will take action against violations of its intellectual property rights. We aim to continue developing and commercializing Professor Stig Steen’s media in the best possible manner in order to create value for patients, customers and shareholders. The initiation of legal proceedings to safeguard XVIVO Perfusion’s exclusive rights to Vivoline Medical’s media developed by Professor Stig Steen is part of this strategy.”
