ArcherDX & MGH v. Qiagen: Plaintiff Verdict on NGS Library Prep Patents After 1,855-Day Trial
ArcherDX, LLC and The General Hospital Corporation sued Qiagen Sciences and related entities in the Delaware District Court, asserting two U.S. patents covering amplicon-based next-generation sequencing library preparation against Qiagen's QIAact and QIAseq product lines. A unanimous jury found direct, induced, and contributory infringement — and rejected all invalidity defenses — awarding plaintiffs $1,593,762 in total damages.
Qiagen's QIAact and QIAseq Kits Found to Infringe ArcherDX–MGH NGS Patents
On July 10, 2018, ArcherDX, LLC and The General Hospital Corporation (MGH) filed suit in the District of Delaware against Qiagen Sciences, LLC and a network of related Qiagen entities, alleging infringement of U.S. Patent No. 10,017,810 and U.S. Patent No. 10,450,597. Both patents relate to amplicon-based next-generation sequencing library preparation methods. The accused products were Qiagen's QIAact Kits and QIAseq Kits — commercial NGS library preparation products used in clinical and research oncology workflows.
After a jury trial, a unanimous verdict was rendered on August 27, 2021, finding Qiagen directly infringed claims 16, 17, and 19 of the '810 Patent and claims 1, 5, and 19 of the '597 Patent, and also finding induced and contributory infringement of those same claims. The jury rejected Qiagen's invalidity defenses — including obviousness, lack of written description, and indefiniteness for the '810 Patent, and anticipation, lack of written description, and indefiniteness for the '597 Patent. Final judgment was entered by Judge Maryellen Noreika on August 8, 2023, awarding $841,756 for RNA-related accused products and $752,006 for other accused products, totalling $1,593,762.
The gap between the jury verdict (August 2021) and entry of final judgment (August 2023) — nearly two years — suggests substantial post-trial motion practice, though the specific nature and resolution of any such motions is not detailed in the available record. The case ran for 1,855 days in total. What drove the parties to trial rather than settlement, and whether any post-judgment relief or appeal is contemplated, is not disclosed in the available record.

US10,017,810 & US10,450,597 — Amplicon-Based NGS Library Preparation Methods
Any company developing, manufacturing, or distributing amplicon-based NGS library preparation kits for the U.S. market — particularly oncology panel or liquid biopsy applications — should treat these two patents as live FTO risks. The jury's verdict confirms claim validity across multiple grounds and upheld infringement under direct, induced, and contributory theories, meaning both end-use and supply-chain positions can be exposed. QIAact and QIAseq were the accused products here, but the asserted claims may read more broadly.
Official order — verbatim text
The August 8, 2023 judgment adopts the jury's August 2021 unanimous verdict in full, entering findings on direct, induced, and contributory infringement of specific claims of both the '810 and '597 Patents, and recording that Qiagen failed to establish invalidity on any ground raised. The itemised damages — $841,756 for RNA-related products and $752,006 for other products — indicate the jury distinguished between the two accused product categories. The nearly two-year interval between jury verdict and final judgment entry is notable and suggests post-trial proceedings of unspecified nature occurred before the court entered judgment under Rule 58.
Plaintiff verdict: what the jury's findings mean for both parties
Unanimous jury found direct, induced, and contributory infringement
The jury returned findings on all three infringement theories — direct infringement by Qiagen entities, inducement of third-party infringement, and contributory infringement. It also rejected every invalidity defense Qiagen raised. Judge Noreika entered final judgment under Fed. R. Civ. P. 58 on August 8, 2023, making the verdict enforceable. The Basis of Termination is recorded as judgment on the merits for the plaintiff.
Full merits judgmentArcherDX and MGH secure $1.59M damages across both product lines
Plaintiffs received $841,756 for Qiagen's RNA-related accused products and $752,006 for other accused products — a combined $1,593,762 in damages. Critically, the jury's rejection of all invalidity challenges reinforces the enforceability of the '810 and '597 Patents going forward. These patents remain viable as enforcement assets against other market participants offering competing amplicon-based NGS library prep products.
$1,593,762 total damages awardedQiagen faces damages liability and strengthened patent bar for QIAact/QIAseq
Qiagen's full suite of invalidity arguments — obviousness, written description, indefiniteness, and anticipation — were rejected by the jury, leaving the asserted patent claims intact. The judgment exposes the Qiagen group entities named to the full damages award. Whether Qiagen has pursued or intends to pursue post-trial motions or an appeal is not disclosed in the available record.
All invalidity defenses rejectedValidated patents raise the IP risk bar across the NGS library prep market
The jury's comprehensive verdict — covering direct, induced, and contributory infringement across two patents — signals meaningful enforceability of amplicon-based NGS library prep IP. Competitors or kit manufacturers operating in this space who use similar amplicon-based approaches should treat the '810 and '597 Patents as active enforcement risks. The damages award, while relatively modest, reflects actual commercial sales volumes and does not cap future exposure if infringement continues.

R&D signals in the amplicon-based NGS library prep space
This verdict spotlights key innovation and filing activity around ArcherDX, MGH, and Qiagen in the amplicon sequencing and liquid biopsy diagnostics domain.
ArcherDX and MGH's broader amplicon sequencing patent estate
The '810 and '597 Patents are two validated nodes in what may be a broader filing programme by ArcherDX and The General Hospital Corporation in amplicon-based NGS and liquid biopsy. Mapping their full portfolio — including continuations, divisionals, and co-assigned filings — can reveal the perimeter of their IP position across clinical sequencing workflows.
Portfolio mapping signalFiling trends in amplicon-based NGS library prep methods
Amplicon-based NGS library preparation is an active innovation area, with filings spanning primer design, adapter ligation, target enrichment, and error-correction methods. Tracking publication trends in this space can reveal whether the technology is consolidating around a few dominant assignees or whether white space remains for new entrants developing differentiated approaches.
Filing trend watchQiagen's own patent position in NGS reagents and kits
Despite losing this action, Qiagen maintains a substantial patent portfolio in molecular biology reagents, nucleic acid isolation, and NGS sample preparation. Understanding Qiagen's own offensive IP position — including any filings that post-date the asserted patents — provides context for how the competitive landscape may evolve and whether cross-licensing dynamics are in play.
Competitor portfolio reviewAdjacent innovation opportunities near the asserted claim scope
The specific claims litigated — covering amplicon-based library preparation steps — leave potential white space in adjacent approaches such as ligation-based or hybrid-capture library prep methods. R&D teams seeking to develop NGS library prep products outside the validated claim scope of the '810 and '597 Patents should explore these alternative technical pathways and assess their own freedom to operate.

Portfolio viewWhat this verdict signals for the NGS library prep IP landscape
A clean plaintiff sweep — infringement on all theories, invalidity defeated — reshapes the competitive IP risk profile in amplicon-based NGS.
Both patents survived every invalidity challenge — enforcement credibility is high
Qiagen contested the '810 and '597 Patents on obviousness, written description, indefiniteness, and anticipation. All were rejected. For any party operating in amplicon-based NGS library prep, these patents now carry a strengthened presumption of validity reinforced by a jury verdict, making design-around or IPR strategies the more likely defensive routes.
Three-theory infringement finding expands exposure for NGS kit suppliers
The jury's findings on direct, induced, and contributory infringement collectively signal that the patents cover not only direct use of the claimed methods but also the commercial supply of kits that enable or contribute to that use. NGS kit manufacturers and distributors active in the U.S. market should assess whether their products fall within the asserted claim scope of the '810 and '597 Patents.
Two-year post-verdict gap suggests significant post-trial motion activity
Final judgment was entered nearly two years after the jury verdict, consistent with contested post-trial motions practice — potentially JMOL, new trial motions, or supplemental damages briefing. The specific nature and resolution of any such proceedings is not detailed in the available record, but the delay is a material signal for monitoring the appeal posture.
ArcherDX–MGH patent family warrants broad portfolio mapping for NGS players
With two asserted patents validated at trial, the broader ArcherDX and MGH patent portfolios in the amplicon sequencing and liquid biopsy space merit systematic review by any company developing or commercialising NGS library preparation products. Adjacent claims in continuation or divisional applications could extend coverage beyond the specific claims litigated here.
ArcherDX v Qiagen — key questions answered
The jury returned a unanimous verdict on August 27, 2021 finding Qiagen entities directly infringed, induced infringement of, and contributorily infringed specific claims of U.S. Patent Nos. 10,017,810 and 10,450,597. The jury also rejected all of Qiagen's invalidity defenses. Final judgment was entered on August 8, 2023 awarding plaintiffs $1,593,762 in total damages.
The accused products were Qiagen's QIAact Kits and QIAseq Kits — commercially available next-generation sequencing library preparation products. The jury awarded $841,756 attributable to RNA-related accused products and $752,006 for other accused products, indicating both product lines were addressed in the damages assessment.
Claims 16, 17, and 19 of U.S. Patent No. 10,017,810 (the '810 Patent) and claims 1, 5, and 19 of U.S. Patent No. 10,450,597 (the '597 Patent) were found directly infringed, induced infringed, and contributorily infringed by the Qiagen defendants.
Qiagen raised obviousness, lack of written description, and indefiniteness against the '810 Patent claims, and anticipation, lack of written description, and indefiniteness against the '597 Patent claims. The jury rejected all of these defenses, leaving the asserted claims valid and enforceable.
The jury returned its verdict on August 27, 2021, but formal final judgment under Fed. R. Civ. P. 58 was not entered until August 8, 2023 — a gap of nearly two years. The specific nature and resolution of any post-trial proceedings during that interval are not detailed in the available record.
