Short Summary
Abbott Diabetes Care Inc.'s IPR challenge against DexCom's glucose monitoring patent was instituted by the PTAB. The Board found a reasonable likelihood of success on anticipation and obviousness grounds over prior art reference Gross, despite acknowledging examination complexity. This decision advances Abbott's efforts to invalidate key claims in the medical device space.
Detailed Summary
The Patent Trial and Appeal Board (PTAB) decided to institute an Inter Partes Review (IPR) petition filed by Abbott Diabetes Care Inc. against DexCom, Inc.'s patent 10709364. The petitioner challenged eight claims based on anticipation and obviousness over the prior art reference Gross US 6,275,717 B1. Although the Board noted technical complexities in the file history that complicated the initial examination, it ultimately determined there was a reasonable likelihood of success for Abbott regarding at least one challenged claim. The petitioner successfully argued that Gross discloses specific limitations related to transcutaneous sensing and predictive calibration functions inherent to glucose monitoring technology.
