Apple prevails in the patent infringement suit by AliveCor–and got three AliveCor heart monitoring patents invalidated as ‘unpatentable’. In the duel of patent infringement claims dating back to May 2021 between AliveCor and Apple, the US Patent and Trademark Office’s Patent Trial and Appeal Board (PTAB) not only ruled that Apple did not infringe on AliveCor’s patents, but also threw out the AliveCor patents that were the basis for the infringement. AliveCor had sued Apple for patent infringement on their ECG technology in three US patents: No. 10,595,731 (“the ’731 patent”); No. 10,638,941 (“the ’941 patent”); and No. 9,572,499 (“the ’499 patent”) in their Apple Watches 4, 5, and 6. [TTA 29 Apr 21, 9 July 21]
The term ‘unpatentable’ is used when the PTAB deems the patent, even when granted in the past, too obvious or too general. When the PTAB finds that, they throw out the patent and it is no longer valid.
Apple of course crowed that they developed their own patents fully on their own, and not from the time when AliveCor’s ECG monitoring was incorporated into earlier Apple Watches. Apple is up to the Series 8. AliveCor has already announced it will appeal and await the pending ruling from the International Trade Commission (ITC) to block the import of Apple Watches. The ITC’s initial determination in June was positive [TTA 28 June] and AliveCor of course is ‘cautiously optimistic’ on the Final Determination due in a few days (12 December). With the PTAB’s finding, it is far less likely that the ITC will impose an import block when AliveCor’s patents have been invalidated. 9to5Mac, Mobihealthnews

Patent invalidation is a danger in any patent infringement lawsuit. In 2015, Bosch Healthcare, which had bought HealthHero, an early RPM platform marketed as Health Buddy, and ViTelNet, was a serial patent challenger. They went after Philips, Viterion (while owned by Bayer), both to a draw, and won against a slew of barely-out-of-the-cradle companies forgotten by nearly all of us such as Alere Health, MedApps, Waldo Health, and Express MD Solutions. Then they sued Cardiocom in 2012 with the same expectation. Except that a year later, Cardiocom was acquired by Medtronic. Deep-pocketed Medtronic fought back hard–and by 2015, the PTAB invalidated most of Bosch’s key patents. Bosch withdrew from the US market abruptly in 2015.

Given their funding and device development, AliveCor will likely not face Bosch’s fate, but such invalidations have consequences yet to be determined and litigated.
