Untitled case

This patent infringement litigation, Cold Spring Harbor Laboratory v. Guardant Health, Inc., Case No. 1:25-cv-00263-JCG, is currently active in the District of Delaware. The plaintiff, Cold Spring Harbor Laboratory (CSHL), is a not-for-profit educational corporation engaged in research and discovery across various biological fields, including cancer, neuroscience, genomics, quantitative biology, and plant biology. The defendant, Guardant Health, Inc., is an operating company in the early cancer screening field, known for its blood test products.

CSHL has accused Guardant Health's blood test products of infringing U.S. Patent Nos. 10,947,589 and 12,234,510. Both patents are titled "Varietal Counting of Nucleic Acids for Obtaining Genomic Copy Number Information" and broadly relate to methods for obtaining genomic copy number information from a sample of genomic material, a technology pertinent to cancer screening. The case, filed on March 6, 2025, is presided over by Judge Jennifer Choe-Groves. The District of Delaware is a prominent venue for patent litigation due to its specialized court and well-developed body of patent law.

The procedural posture of the case saw a notable development on October 10, 2025, when the court denied Guardant Health's partial motion to dismiss claims for willful infringement. The court found that CSHL had made specific factual allegations supporting pre-suit knowledge of the patents by Guardant Health, including Guardant's involvement in related research and opposition proceedings to CSHL's related European patents. This case is notable within the early cancer screening industry, particularly regarding the intersection of academic research and commercial products, and the scrutiny around allegations of pre-suit willful infringement. An Inter Partes Review (IPR2025-01355) was also filed by Guardant Health Inc. challenging U.S. Patent No. 10,947,589, indicating parallel PTAB proceedings for at least one of the asserted patents.

The case Cold Spring Harbor Laboratory v. Guardant Health, Inc., Case No. 1:25-cv-00263-JCG, has seen several key legal developments since its filing in March 2025.

Filing & Initial Pleadings

• Complaint: Cold Spring Harbor Laboratory (CSHL) filed its complaint for patent infringement against Guardant Health, Inc. on March 6, 2025, in the District of Delaware. CSHL accused Guardant Health's blood test products of infringing U.S. Patent Nos. 10,947,589 and 12,234,510.
• Amended Complaint: An amended complaint was filed, which included claims for willful infringement.

Pre-trial Motions of Substance

• Motion to Dismiss Willful Infringement Claims: Guardant Health filed a partial motion to dismiss claims for willful infringement, arguing that CSHL failed to allege sufficient facts of pre-suit knowledge to support enhanced damages.
• Denial of Motion to Dismiss: On October 10, 2025, Judge Jennifer Choe-Groves denied Guardant Health's motion to dismiss. The court found that CSHL had made specific factual allegations supporting pre-suit knowledge, including Guardant's involvement in related research and opposition proceedings to CSHL's related European patents. The court noted that while any of these items in isolation might be too speculative, taken collectively, they were sufficient to support the claim of pre-suit willful infringement.

Parallel PTAB IPR/PGR Proceedings

• IPR2025-01355: Guardant Health Inc. filed an Inter Partes Review (IPR2025-01355) challenging U.S. Patent No. 10,947,589. While the status of IPR2025-01355's institution decision is not explicitly detailed in the provided search results, other IPRs filed around the same time have seen institution decisions in late 2025. It is worth noting that the PTAB under Director Squires has increasingly denied IPR petitions on discretionary grounds, with a focus on factors like "settled expectations" and the age of the patent. This trend has seen petitions for patents less than six years old more likely to be instituted.
