Apple told the US Court of Appeals for the Federal Circuit, that the US International Trade Commission's decision was based on a "series of substantively defective patent rulings."
Apple urged a US appeals court on Friday to overturn a US
trade tribunal’s decision to ban imports of some Apple Watches in a patent
dispute with medical-monitoring technology company Masimo.
Apple told the US Court of Appeals for the Federal Circuit,
that the US International Trade Commission’s decision was based on a “series of
substantively defective patent rulings,” and that Masimo failed to show it had
invested in making competing U.S. products that would justify the order.
Representatives for Apple and Masimo did not immediately
respond to requests for comment on the filing.
Irvine, California-based Masimo has accused Apple of hiring
away its employees and stealing its pulse oximetry technology after discussing
a potential collaboration. Apple first introduced pulse oximetry to its Series
6 Apple Watches in 2020.
Masimo convinced the ITC on Dec. 26 to block imports of
Apple’s latest-edition Series 9 and Ultra 2 smartwatches after finding that
their technology for reading blood-oxygen levels infringed Masimo’s patents.
Apple temporarily resumed sales of the watches the next day
after persuading the Federal Circuit to pause the ban. The appeals court
reinstated the ban in January, leading Apple to remove pulse oximetry
capabilities from watches sold during the appeal, which Apple has said could
last at least a year.
US Customs and Border Protection separately determined in
January that redesigned versions of the watches did not violate Masimo’s rights
and would not be not subject to the ban. Masimo said in a court filing that the
watches “definitively do not contain pulse oximetry functionality.”
Apple told the Federal Circuit on Friday that the ban could
not stand because a Masimo wearable covered by the patents was “purely
hypothetical” when it filed its ITC complaint in 2021.
The tech giant also argued that Masimo’s patents were
invalid and that its watches did not infringe them.
