Bayer & Monsanto v. Glass: Permanent Injunction Over GM Soybean Seed Patents
Bayer AG and Monsanto Technology LLC brought a patent infringement action against Missouri farmer Danny Glass in January 2023, asserting two foundational GM soybean biotechnology patents. The case closed after 799 days with a consent judgment permanently enjoining Glass from saving, planting, or transferring seed containing Plaintiffs’ patented technologies.
Monsanto’s seed biotech patents enforced against Missouri grower via consent order
Filed on 25 January 2023 in the Eastern District of Missouri before Judge John A. Ross, this action pitted Bayer AG and its subsidiary Monsanto Technology LLC against Danny Glass, an individual defendant. The plaintiffs alleged infringement of US7838729B2, covering the soybean event MON89788 and detection methods, and US9944945B2, covering chloroplast transit peptides used to target the dicamba-degrading enzyme DMO in Roundup Ready 2 Xtend® crops. The accused conduct centred on saving and replanting patented GM soybean seed and applying unapproved dicamba-based herbicide formulations to those crops.
The case closed on 3 April 2025 through a consent judgment — a court-entered order agreed to by both parties — rather than a contested trial verdict. The consent judgment permanently enjoins Glass from making, using, saving, planting, selling, offering for sale, importing, or otherwise transferring any soybean or other seed containing Monsanto’s patented biotechnologies without express written permission. It also bars him from applying unapproved dicamba formulations to Roundup Ready 2 Xtend® crops. A permanent injunction of this scope constitutes a complete legal win for the plaintiffs on the injunctive relief sought.
At 799 days, the case ran longer than many seed-enforcement actions that settle early, suggesting some degree of contested negotiation before terms were agreed. The public record does not disclose any monetary damages, royalty payment, or cost award, which is consistent with consent judgments in which the primary plaintiff objective is cessation of infringing conduct rather than financial recovery. What remains unknown is whether any confidential financial terms were reached outside the court order, and whether Bayer/Monsanto simultaneously pursued or settled related technology-stewardship agreement claims.

Consent judgment explained: what the permanent injunction means for both parties
What a consent judgment means in patent enforcement
A consent judgment is a court-entered order reflecting the parties’ agreed resolution. It carries the full force of a judicial order — including contempt exposure for breach — without requiring the plaintiff to prove infringement at trial. Here, the court entered a permanent injunction on agreed terms, meaning Glass stipulated to the injunctive relief. This is not a voluntary dismissal; it is an enforceable court order that remains in effect indefinitely.
Enforceable court orderBayer and Monsanto secure full injunctive relief sought
The consent judgment delivers precisely the remedy Bayer and Monsanto typically pursue in seed-enforcement cases: a permanent, court-enforceable ban on all infringing conduct. Glass is prohibited from the full spectrum of infringing acts — saving, planting, selling, transferring seed, and applying unapproved herbicide formulations. Future violation would expose Glass to civil contempt proceedings, a powerful deterrent. The absence of a disclosed damages award is consistent with Monsanto’s long-standing enforcement strategy of prioritising injunctive compliance over financial recovery from individual growers.
Full injunctive relief grantedGlass permanently barred from patented seed activities
For Glass, the consent judgment means permanent court supervision of his seed-sourcing and herbicide practices. He is barred from any use of seed containing Monsanto’s patented GM traits — including MON89788 and DMO/chloroplast transit peptide technologies — without written permission. While consenting to the injunction avoids the cost and risk of a full trial, the injunction’s scope is broad and indefinite. Any future non-compliance could be addressed through contempt proceedings rather than a new lawsuit, raising the stakes of any future deviation.
Permanent conduct restrictionEnforcement signal for the GM seed technology stewardship regime
This case reinforces Bayer/Monsanto’s consistent strategy of pursuing individual growers through federal district courts to maintain the integrity of their technology licensing regime. Consent judgments against named defendants create public record deterrence — visible to other growers in the region. For IP professionals monitoring agricultural biotech, the case signals that US7838729B2 and US9944945B2 remain actively asserted patents, and that the Eastern District of Missouri continues to serve as a preferred enforcement venue for Monsanto’s seed IP portfolio.

Official order — verbatim text
The consent judgment’s injunction is drafted in unusually broad terms, covering not merely the specific acts alleged in the complaint but the full universe of possible infringing conduct — making, using, saving, planting, selling, offering to sell, importing, or transferring any seed containing either patent’s biotechnology. This language tracks the statutory remedies of 35 U.S.C. § 283 and leaves no ambiguity about scope. The dual prohibition — on both seed activities and unapproved herbicide application — reflects the integrated nature of Monsanto’s Roundup Ready 2 Xtend system and confirms that both patents remain operative enforcement instruments.
US7838729B2 & US9944945B2 — GM Soybean Event and Herbicide-Tolerance Patents
US7838729B2 (application no. US11/758659) covers the soybean transformation event MON89788 — the genetic insertion event underlying Roundup Ready 2 Soybean — and methods for its detection. US9944945B2 (application no. US14/539923) covers chloroplast transit peptides engineered to efficiently deliver the dicamba mono-oxygenase (DMO) enzyme into plant chloroplasts, enabling the dicamba herbicide tolerance trait in Roundup Ready 2 Xtend® soybeans. Together, these patents protect both the GM event itself and the molecular machinery that confers herbicide tolerance, covering the core commercial value of Monsanto’s second-generation soybean platform.
For competitors and independent seed developers, these two patents represent a significant FTO obstacle in the herbicide-tolerant soybean space. US7838729B2’s event-specific claims make it difficult to develop MON89788-based products without a licence, while US9944945B2’s chloroplast transit peptide claims have potential reach into any DMO-based herbicide tolerance engineering. The Roundup Ready 2 Xtend® platform is planted on tens of millions of acres annually in the US, making these among the most commercially significant GM crop patents in active enforcement. Bayer’s willingness to litigate against individual growers reinforces that the portfolio is actively policed at every level of the supply chain.
Should you run an FTO against US7838729B2 and US9944945B2?
Any company breeding, developing, or commercialising herbicide-tolerant soybean varieties — or working with chloroplast-targeted enzyme delivery systems in crop biotech — should treat these patents as priority FTO targets. US9944945B2’s transit peptide claims are potentially broad enough to implicate engineering approaches beyond MON89788 itself. Contract seed producers, trait licensors, and growers in technology stewardship programmes are all within the enforcement perimeter Bayer/Monsanto has demonstrated it will police through federal court action.

What this case signals for the agricultural biotech IP landscape
Bayer and Monsanto’s consent judgment against Glass is one data point in a systematic enforcement programme that shapes how GM seed IP is policed across the US Midwest.
Consent judgments serve as public deterrents in seed IP enforcement
Monsanto’s enforcement model relies on court-entered consent judgments as much as financial damages. A named, publicly docketed permanent injunction signals to other growers in the region that seed saving will be pursued to a court order. IP professionals advising agricultural clients should note that the E.D. Missouri is a high-frequency venue for these actions and that resistance through litigation carries significant risk.
Both asserted patents remain live enforcement tools for Bayer/Monsanto
US7838729B2 and US9944945B2 were both actively asserted and specifically named in the injunction order, confirming their continued enforceability. R&D teams developing soybean trait technologies or herbicide-tolerance systems should treat these patents as active FTO risks, particularly where MON89788 event detection or chloroplast-targeted DMO expression is involved in product development or breeding programmes.
Bayer v Danny — key questions answered
Two patents were asserted: US7838729B2, covering soybean transformation event MON89788 and detection methods, and US9944945B2, covering chloroplast transit peptides for efficient DMO enzyme targeting in herbicide-tolerant crops. Both patents underpin the Roundup Ready 2 Xtend® soybean platform.
The case closed on 3 April 2025 via a consent judgment. The court entered a permanent injunction prohibiting defendant Danny Glass from making, using, saving, planting, selling, offering to sell, importing, or transferring any seed containing Monsanto’s patented biotechnologies without written permission, and from applying unapproved dicamba formulations to Roundup Ready 2 Xtend® crops.
A consent judgment is a court-entered order agreed to by both parties that carries full judicial force. For Glass, it means he is permanently subject to the injunction’s restrictions. Any future violation would expose him to civil contempt proceedings, which can result in fines or other sanctions without requiring Monsanto to file a new lawsuit. The injunction has no expiration date based on the public record.
Yes. US9944945B2 was specifically named in the permanent injunction entered in this case in April 2025, confirming it remains an active enforcement asset. Companies working in the chloroplast transit peptide or DMO-based herbicide tolerance space should treat this patent as a live FTO risk and monitor Bayer/Monsanto’s continuation filing activity.
Monsanto’s long-standing enforcement strategy encompasses individual growers who save patented GM seed, as each act of saving and replanting constitutes independent infringement under the patent exhaustion doctrine as interpreted post-Bowman v. Monsanto (2013). Pursuing individual growers through federal court and securing public consent judgments serves a deterrence function across the broader farming community, reinforcing the technology stewardship agreements that govern licensed GM seed use.
