Dispute Summary
Eunsung Global Corp. has filed an IPR petition seeking cancellation of 41 claims of HydraFacial's skin‑treatment patent, arguing obviousness over four prior‑art references. The petition asserts that the examiner never considered the Karasiuk‑Palmer, Greenberg, and Trueba teachings and that discretionary denial is not warranted.
