Item 8.01	Other Events.

On March 30, 2026, Seer, Inc. announced that the Patent Trial and Appeal Board (“PTAB”) of the U.S. Patent and Trademark Office issued a Final Written Decision on March 23, 2026, in an inter partes review of U.S. Patent No. 11,435,360 B2. The inter partes review (IPR2024-01473) was filed by PreOmics GmbH and Biognosys AG, challenging claims 1-4, 6, 7, 17, and 22-25 of the ‘360 patent. In its Final Written Decision, the PTAB determined that the petitioners failed to demonstrate the unpatentability of claims 2, 3, 7, 23, and 24 of the ‘360 patent, resulting in a total of 23 claims, the five upheld and another 18 unchallenged, remaining valid and enforceable. The upheld claims include limitations relating to the depth and dynamic range of proteins detected by the claimed methods and the nature of the particles used in the methods. The PTAB determined that claims 1, 4, 6, 22, 24, and 25 were unpatentable.

Either party choosing to pursue appeal must file a notice of appeal by May 25, 2026.

A copy of the press release is attached hereto as Exhibit 99.1 and is incorporated herein by reference.
