Sharda USA v. FMC Technologies: Federal Circuit Vacates Insecticide Patent Ruling
Sharda USA, LLC appealed to the Federal Circuit in a patent infringement dispute with FMC Technologies over two insecticide patents covering Sharda’s WINNER product. In 315 days, the Court of Appeals vacated the lower court’s decision and remanded the case, resetting the litigation clock for both parties.
Federal Circuit resets insecticide patent fight between Sharda and FMC
Sharda USA, LLC and FMC Technologies, Inc. are adversaries in a patent infringement action centred on insecticide technology. The dispute involves two granted US patents — US9107416B2 and US9596857B2 — that cover formulations and methods relevant to Sharda’s WINNER insecticide product. The case reached the Court of Appeals for the Federal Circuit under docket number 24-2335, filed in September 2024.
The Federal Circuit issued its ruling on 1 August 2025, ordering the lower court’s decision to be vacated and the matter remanded. A vacatur means the prior ruling has no legal force; neither party can rely on it as precedent or as a final resolution of the infringement claims. The remand directs the lower tribunal to reconsider the dispute, potentially with corrected legal standards or factual findings.
The 315-day resolution at the appellate level is relatively efficient for Federal Circuit matters, suggesting the panel may have identified a discrete legal error rather than requiring extensive merits re-examination. The specific grounds for vacatur are not detailed in the public docket summary, leaving the ultimate liability question unresolved. What drove the panel’s decision — claim construction, procedural error, or substantive patent law — will be critical context as the case proceeds below.

Federal Circuit vacates: what the remand means for both parties
Vacatur nullifies the lower ruling — case must restart below
A Federal Circuit vacatur wipes the prior decision from the record. It is not an affirmance or a win for either side on the merits. The lower tribunal must now reconsider the case, typically under corrected legal guidance issued by the Federal Circuit. Until remand proceedings conclude, no final liability determination exists for either US9107416B2 or US9596857B2.
Decision nullifiedSharda gets a second chance — but so does FMC
For Sharda USA as appellant, vacatur is a qualified win: the adverse lower decision no longer stands. However, remand is not a finding of infringement. Sharda must re-litigate the relevant issues under whatever corrected framework the Federal Circuit prescribed. The patents remain in force and enforceable, but their scope or validity may be re-examined on remand.
Outcome still openFMC loses the favourable lower ruling — faces renewed exposure
FMC Technologies, Inc. had secured a favourable outcome at the tribunal below, which the vacatur has now erased. The company faces renewed litigation risk on remand without the protection of the prior decision. FMC’s legal team — led by MoloLamken LLP — will need to rebuild its defence from the revised legal framework the Federal Circuit has signalled is required.
Prior win erasedInsecticide sector faces continued IP uncertainty
Until remand proceedings produce a final outcome, the scope of patent protection around WINNER-type insecticide formulations remains legally unsettled. Competitors and distributors operating in this product space should treat the two patents as active enforcement risk. Licensing decisions and freedom-to-operate assessments made in reliance on the prior lower decision should now be revisited.

Official order — verbatim text
The Federal Circuit’s order — ‘VACATED AND REMANDED’ — is a directive of legal nullification, not a merits ruling. At the appellate level, vacatur signals the panel found reversible error in the lower proceeding, most commonly a misapplication of law, an incorrect claim construction standard, or an unsupported factual finding. Critically, neither party prevails on the underlying infringement question; both must return to the lower tribunal. The remand instruction places the procedural initiative back with the originating court to apply corrected legal standards to the facts of the WINNER insecticide infringement dispute.
US9107416B2 & US9596857B2 — Insecticide formulation patents at the centre of dispute
US9107416B2 (application number US12/158487) and US9596857B2 (application number US14/662480) are granted US patents covering insecticide formulations and associated methods. These patents protect the specific compositions and preparation approaches underlying Sharda’s WINNER product line. The application sequences suggest US9596857B2 is a continuation or related filing to US9107416B2, extending coverage across formulation variations. Both patents are held by Sharda USA, LLC and were actively asserted in this Federal Circuit appeal.
In the agrochemical sector, insecticide formulation patents are high-value enforcement assets because the protected compositions often define the commercial product directly. A company holding two layered patents — on both the compound formulation and its methods — creates a stacked IP barrier against generic or competing products. FMC Technologies’ position in this dispute, and the Federal Circuit’s willingness to hear the appeal, underscores that the scope and validity of these patents carries meaningful competitive consequence for the broader crop protection market.
Should you run an FTO analysis against US9107416B2 and US9596857B2?
Any company formulating, distributing, or commercialising insecticide products in the composition or method space covered by WINNER-type agrochemicals should treat these two patents as live risk assets. The Federal Circuit vacatur means no court has definitively narrowed their scope — both claims remain fully asserted and unresolved. R&D teams evaluating new insecticide compositions or formulation processes should flag these patents as priority items in FTO clearance workflows.
PatSnap Eureka’s FTO Search Agent can map the claim language of US9107416B2 and US9596857B2 against your specific product formulations, identify prior art relevant to any PTAB challenge, and surface continuation risk from the US14/662480 application family. As this litigation remains live through remand, ongoing patent landscape monitoring will be as important as the initial FTO clearance — Eureka’s alert tools can track new filings in the Sharda portfolio automatically.

What this case signals for the agrochemical patent IP landscape
A Federal Circuit vacatur in an insecticide patent dispute resets enforcement dynamics and raises monitoring urgency for the sector.
Vacatur does not end the case — monitor remand proceedings actively
Patent professionals tracking Sharda USA v. FMC Technologies should not treat the Federal Circuit’s order as a final resolution. The vacatur restores live litigation risk on both sides. Any competitor or licensee with exposure to WINNER insecticide formulations should maintain docket monitoring until a final merits decision is issued on remand.
Both patents remain enforceable during remand — FTO exposure persists
US9107416B2 and US9596857B2 are granted patents with no cancellation or invalidation on the record. The vacatur addresses the lower ruling only, not patent validity. Companies working with insecticide formulations in the scope of these claims should continue to treat them as live enforcement assets until remand concludes or the patents are formally challenged.
SHARDA v FMC — key questions answered
The Federal Circuit’s vacatur in case 24-2335 nullifies the lower court’s decision in the WINNER insecticide patent dispute. Neither party wins on the merits; the matter is remanded for reconsideration under corrected legal standards. Both US9107416B2 and US9596857B2 remain active enforcement assets while remand proceedings continue.
Two patents are asserted: US9107416B2 (application US12/158487) and US9596857B2 (application US14/662480). Both cover insecticide formulations relevant to Sharda’s WINNER product. They appear to form a related patent family, with the second patent potentially extending coverage of the first.
The product at the centre of the dispute is Sharda’s WINNER insecticide. The infringement action alleges that FMC Technologies’ conduct infringed the formulation and method claims of the two asserted patents covering this product category.
Sharda USA was represented by Benesch, Friedlander, Coplan & Aronoff LLP, with attorneys Manish Mehta, Mircea Tipescu, and Tara Mythri Raghavan. FMC Technologies was represented by MoloLamken LLP, with attorneys including Jeffrey A. Lamken, Benoit Quarmby, Jennifer Elizabeth Fischell, and others.
No. The Federal Circuit’s vacatur and remand order means the underlying infringement question — whether FMC Technologies infringed US9107416B2 or US9596857B2 — has not been finally adjudicated. The case returns to the lower tribunal for further proceedings. A final merits determination remains pending as of the close of the Federal Circuit appeal.
