FISHER & PAYKEL HEALTHCARE FILES A PATENT INFRINGEMENT PROCEEDING
AGAINST RESMED IN AUSTRALIA
Auckland, New Zealand, 12 December 2017 - Fisher & Paykel Healthcare announced today that it
has filed a patent infringement proceeding in the Federal Court of Australia against ResMed Ltd
and several of its related companies.

Fisher & Paykel Healthcare and ResMed are currently engaged in patent proceedings in multiple
countries. In the additional proceeding filed today, Fisher & Paykel Healthcare alleges that
ResMed’s AirSense 10, AirCurve 10, S9 and S9 VPAP flow generators, Lumis non-invasive
ventilators, ClimateLine and ClimateLineAir heated air tubing and HumidAir heated humidifier
infringe four patents held by Fisher & Paykel Healthcare. These products are used to treat
respiratory conditions. Fisher & Paykel Healthcare is seeking a range of remedies, including
damages and injunctions preventing the manufacture and sale of these products by ResMed in
Australia.

Lewis Gradon, Managing Director and Chief Executive Officer said, “Over the past 45 years we
have made a considerable investment in our research and development programme and built up a
significant patent portfolio. We take the infringement of our intellectual property rights very
seriously and we will continue to take whatever action is necessary to protect our investment.”

The company advises that the earnings guidance for its 2018 full year results, as provided on 21
November 2017, remains unchanged.
