Litigation Involving US Patent 12,377,204

As of April 26, 2026, US Patent 12,377,204 is involved in at least one known litigation. Details of the case are provided below.

Haemonetics Corp. v. Terumo BCT, Inc.

  • Plaintiff: Haemonetics Corp.
  • Defendant: Terumo BCT, Inc.
  • Jurisdiction: U.S. District Court for the District of Colorado.
  • Case Number: 1:25-cv-01409-RMR-SBP.
  • Filing Date of Action: The initial complaint was filed on May 5, 2025. However, US Patent 12,377,204 was specifically added to the lawsuit in the Second Amended Complaint on August 12, 2025.
  • Outcome or Current Status: The case is currently active. Haemonetics alleges that Terumo BCT infringes upon the asserted patents, including the '204 patent, which cover systems for collecting plasma based on a donor's specific characteristics. Haemonetics is seeking injunctive relief and compensatory damages. Terumo BCT denies the allegations and, as of September 2, 2025, had filed a partial motion to dismiss the complaint, arguing that the asserted patents are invalid. Terumo BCT has also initiated inter partes review (IPR) and post-grant review (PGR) proceedings with the U.S. Patent and Trademark Office challenging the validity of asserted patents. A motion to stay the district court litigation pending the resolution of these PTAB challenges was filed by Terumo on November 7, 2025, and is pending. A scheduling order indicates that claim construction is anticipated to begin in early 2026.
