New Zealand's Fisher & Paykel Healthcare Corp. Ltd. filed a patent infringement complaint against ResMed Inc., seeking to block certain of its products.
The company asked the U.S. International Trade Commission to ban the importation and sale of San Diego-based ResMed's AirFit P10 range of nasal pillows masks in the U.S. According to Fisher & Paykel, ResMed's AirFit P10 masks, AirFit P10 for her masks and AirFit P10 for AirMini masks infringe five of its patents.
The products are used to treat obstructive sleep apnea.
ResMed recently made a similar request with the ITC, asking the regulator to block Fisher & Paykel's Simplus full face mask, Eson nasal mask and Eson 2 nasal mask.
Fisher & Paykel Healthcare designs and sells products and for use in respiratory care, acute care and surgery.
