Omni Medsci, Inc. v. Whoop, Inc.

This patent infringement litigation, Omni Medsci, Inc. v. Whoop, Inc., was filed on February 5, 2025, in the Delaware District Court under case number 1:25-cv-00140. The plaintiff, Omni Medsci, Inc., is characterized as a non-practicing entity (NPE) that seeks to commercialize patents through partnerships rather than manufacturing its own products. Omni Medsci is part of a larger "Omni family of companies" focused on optical technology, with many asserted patents originating from University of Michigan professor Mohammed N. Islam. The defendant, Whoop, Inc., is an operating company and a prominent American wearable technology firm, headquartered in Boston, Massachusetts, known for its health trackers that monitor metrics like strain, recovery, and sleep. The core of the dispute involves Whoop's wearable health trackers, such as the WHOOP Strap, which Omni Medsci alleges infringe its intellectual property.

The primary patent at issue, US Patent 11,160,455, is titled "Wearable device for physiological monitoring" and generally describes a wearable device featuring a light source with semiconductor components to generate optical light, lenses to deliver this light to tissue, and a detection system to receive reflected light and produce an output signal. The patent details a configuration where multiple light-emitting diodes and spatially separated detectors are arranged on one or more arcs to facilitate physiological measurements, particularly with near-infrared or short-wave infrared light sources. While initially assigned to Judge Jennifer L. Hall, the case is currently presided over by Judge William C. Bryson. The District of Delaware is a critical venue for patent litigation, often chosen due to the high number of corporations incorporated in the state, its judges' established expertise in patent law, and a predictable docket with sophisticated juries, which became more pronounced after the Supreme Court's TC Heartland decision.

This case is notable for several reasons, including Omni Medsci's history as an NPE with a pattern of asserting patents from the same inventor against other major technology companies, such as Apple, Samsung, Fossil, OnePlus, and Oura Health. Whoop has responded by filing multiple Inter Partes Review (IPR) petitions against the asserted patents at the USPTO, a common strategy by defendants to challenge patent validity outside of district court. Although an initial motion to stay the district court proceedings pending IPR outcomes was denied, a renewed motion was later granted, conditioned on Whoop agreeing to be bound by IPR estoppel provisions, indicating the significant role of PTAB proceedings in this litigation. The dispute also highlights the increasing patent scrutiny within the competitive and rapidly evolving wearable health technology industry.

Ltd. et al. against Omni Medsci patents, such as IPR2025-01254 and PGR2025-00063 related to U.S. Patent No. 12,268,475, are mentioned in Whoop's motion to stay as part of "related litigation" in the Eastern District of Texas, but are not directly initiated by Whoop in this Delaware case [cite: 7, 9, 10 in prior step].
