Known litigation involving US patent RE48479 is detailed below, primarily stemming from a parallel district court case referenced in Patent Trial and Appeal Board (PTAB) proceedings.

Case 1: Happy Products, Inc. v. Ontel Products Corporation

  • Plaintiff(s): Happy Products, Inc.
  • Defendant(s): Ontel Products Corporation
  • Jurisdiction: United States District Court for the District of New Jersey (DNJ)
  • Case Number: 2:24-cv-09819
  • Filing Date: The IPR documents refer to a "2002 Complaint for Patent Infringement," but also a "2012 DNJ-2-24-cv-09819 Docket Sheet". Given the IPR filing date in late 2025, the "2:24-cv-09819" case number suggests a filing date in 2024, which would be consistent with a parallel litigation. The exact filing date for 2:24-cv-09819 is not directly available in the provided snippets, but the references within the IPR suggest a complaint was filed by the patent owner against Ontel.
  • Outcome or Current Status: This case is a parallel litigation to an Inter Partes Review (IPR) proceeding (IPR2025-01536) before the Patent Trial and Appeal Board (PTAB). In the IPR, Ontel Products Corporation challenged the patent, but institution of the inter partes review was denied on February 10, 2026, based on discretionary considerations under 35 U.S.C. § 314(a). The denial of institution means the validity challenge at the PTAB did not proceed. The district court litigation itself saw motions, including a motion to dismiss by the defendant, and orders denying a stay of litigation requested by the defendant. The IPR documents mention a "Pretrial Scheduling Order" and a "Joint Letter to Magistrate Judge Almonte re Dispute Concerning Stay". The specific outcome or current status of the district court case (2:24-cv-09819) itself, beyond the denial of a stay and the refusal to institute IPR, is not explicitly detailed in the provided search results.

  • Outcome/Status: Institution of inter partes review was denied on February 10, 2026, based on discretionary considerations. Ontel Products Corporation subsequently requested a refund of post-institution fees on April 14, 2026.
