Fisher & Paykel Healthcare has filed patent infringement proceedings in US District Court, alleging that certain ResMed CPAP devices, masks, and accessories used to treat obstructive sleep apnea infringe on F&P patents, according to an August 15th press release from F&P.

The suit involves ResMed’s AirSense 10 and AirCurve 10 range of flow generator products, ClimateLineAir heated air tubing for use with such flow generator products, and Swift LT and Swift FX masks, according to an F&P press release.

Fisher & Paykel Healthcare is “seeking all available remedies, including damages and injunctive relief.”

“Fisher & Paykel Healthcare has invested substantial resources in the research and development of its technologies over the past 45 years. The company has protected that investment through the development of a significant portfolio of more than 1,400 issued and pending patents, and takes infringement of its intellectual property rights very seriously,” said Lewis Gradon, CEO & managing director, Fisher & Paykel Healthcare.
