This will hurt you more than me – validity of IV catheter patent upheld

Written by Peter Heerey AM, QC, Tom Cordiner & Alan Nash. In the proceeding B. Braun Melsungen AG v Multigate Medical Devices Pty Ltd [2014] FCA 1110, Pagone J held certain claims of two of B Braun’s patents for safety IV catheters valid and infringed by the conduct of Multigate. Both patents are for a safety needle protecting device for an intravenous catheter. Both claim the priority date of 12 June 1998 through the same chain of intermediate patents.

The applicants (Damorgold) were the owner and exclusive licensee of a patent for a spring assisted blind mechanism, which had a priority date of 25 August 1999. The issue of the licensee’s right to relief was stayed. Damorgold claimed that JAI Products had infringed a suite of claims of the patent and JAI Products asserted the patent was invalid. In the end, Middleton J found two claims infringed and valid.
