II. Technology and Patent(s)-in-Suit Analysis

U.S. Patent No. 9,856,179 - "Method and Composition for Agricultural Potassium-Plus Fertigation"

The patent-in-suit is U.S. Patent No. 9,856,179, issued January 2, 2018 (the "’179 Patent"). (Compl. ¶150; ’179 Patent, p. 1).

The Invention Explained

  • Problem Addressed: The patent describes how conventional fertilizer formulations, when added to irrigation water, increase the concentration of inorganic salts. In modern micro-irrigation systems, which use fine emitters to conserve water, this increased salt load can cause minerals to precipitate and form deposits, leading to system "plugging." This clogging results in uneven water and nutrient distribution and can cause a complete shutdown of the irrigation system. (’179 Patent, col. 5:6-16).
  • The Patented Solution: The invention is a "potassium-plus nutrient feedstock" composition designed for fertigation that avoids the plugging problem. The key is its use of potassium formate as the potassium source, which, along with other specified "yield-assist constituents," creates a highly soluble, stable formulation. This composition is designed to have a high nutrient content while lacking constituents known to cause precipitation, such as sulfates or certain phosphates, thereby allowing for effective use in sensitive micro-irrigation equipment. (’179 Patent, Abstract; col. 6:5-27). Exhibit 3 to the complaint provides a schematic of an emitter irrigation system, illustrating the main water line, lateral lines, and emitters where the patented composition is intended for use (’179 Patent, Fig. 1; Compl. Ex. 3).
  • Technical Importance: This technology enables reliable "fertigation"—the simultaneous delivery of fertilizer and water—through high-efficiency micro-irrigation systems, a practice critical to precision agriculture and water conservation. (’179 Patent, col. 5:41-50).

Key Claims at a Glance

  • The complaint asserts infringement of at least independent claim 14. (Compl. ¶155).
  • The essential elements of independent claim 14 are:
    • A treated irrigation water comprising a potassium-plus nutrient feedstock and irrigation water,
    • wherein said potassium-plus nutrient feedstock is comprised of from 10 to 50 wt. percent potassium formate
    • and from 1 to 35 wt. percent additional yield-assist constituent(s). (’179 Patent, col. 12:30-35).
  • The complaint reserves the right to assert other claims discovered to be infringed. (Compl. ¶156).

III. The Accused Instrumentality

Product Identification

The accused instrumentalities are several fertilizer formulations, including "Fusion/Rogue 0-6-18," "Fusion/Rogue 9-0-14," and "Rogue 9-4-14," collectively referred to as the "'179 Accused Products." (Compl. ¶152).

Functionality and Market Context

The complaint alleges these are liquid fertilizer formulations made by Defendant Custom AG at the direction of Defendants Agrigenix and Mahoney, and subsequently sold by Agrigenix and Mahoney to their customers for use in agricultural fertigation. (Compl. ¶151). The complaint alleges these products are "pirated" from Deerpoint’s confidential information and were launched to directly compete with Deerpoint's own product line. (Compl. ¶¶74-75, 80).

IV. Analysis of Infringement Allegations

The complaint alleges that infringement details are provided in a claim chart (Exhibit 4) filed separately under seal; this exhibit was not provided for analysis. (Compl. ¶159). The infringement theory, as articulated in the complaint, is that the Defendants directly infringe, induce others to infringe, and contribute to the infringement of at least claim 14 of the ’179 Patent by making, using, selling, and offering for sale the accused fertilizer formulations. (Compl. ¶152). The complaint alleges that the '179 Accused Products, which constitute the "potassium-plus nutrient feedstock," meet the limitations of claim 14 when mixed with irrigation water by an end-user. (Compl. ¶155).

Identified Points of Contention

  • Scope Questions: Claim 14 recites a "treated irrigation water," a composition formed when the accused fertilizer ("feedstock") is mixed with water. A central question is whether Defendants, who are alleged to primarily make and sell the feedstock precursor, can be held liable for direct infringement. The analysis may therefore focus heavily on the alternative claims for indirect infringement, which require proof of specific knowledge and intent regarding the end-user's infringing act of creating the final composition.
  • Technical Questions: A key evidentiary question will be whether the chemical composition of the '179 Accused Products falls within the claimed ranges. The complaint does not provide an independent chemical analysis, instead relying on allegations of trade secret theft to assert that the formulations are copies. A primary technical dispute will likely center on whether the accused products contain "potassium formate" and "additional yield-assist constituent(s)" in the specific weight percentages required by claim 14.

V. Key Claim Terms for Construction

"additional yield-assist constituent(s)"

  • Context and Importance: This term defines the active ingredients in the composition beyond potassium formate. The scope of this term is critical, as it will determine what other substances can be included in an infringing product. Practitioners may focus on this term because its definition will dictate whether Defendants' specific formulations are covered by the claim.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The specification defines the term functionally as a "non-potassium-formate constituent that is beneficial to the crop's nutrient-uptake and/or soil condition" and provides a non-exhaustive list of examples, including macronutrients (N, P), micronutrients (Zn, Cu, Fe, Mn), and acid. (’179 Patent, col. 6:25-28, col. 8:3-7). This language may support a broad construction covering a wide range of common agricultural additives.
    • Evidence for a Narrower Interpretation: The patent provides specific examples of such constituents in its embodiments, such as urea, di-ammonium phosphate (DAP), and EDTA-chelated metals. (’179 Patent, col. 6:50-58, col. 7:55-65). A defendant may argue the term should be limited by these examples or by other characteristics of the preferred feedstock, such as having no components with a molecular weight greater than 1,000. (’179 Patent, col. 8:31-34).

"potassium-plus nutrient feedstock"

  • Context and Importance: This is the name the patent gives to the concentrated formulation before it is mixed with water. The infringement case rests on the accused products being this "feedstock."
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: Plaintiff may argue that "feedstock" is simply a label for any composition that meets the recited structural limitations of the claim (i.e., containing potassium formate and yield-assist constituents in the specified amounts).
    • Evidence for a Narrower Interpretation: Defendants may argue that the term is defined by more than its ingredients, pointing to specification language describing the feedstock as having other properties, such as a "minimal amount of water" and "no essential yield-adverse constituent." (’179 Patent, col. 8:26-34). An argument could be made that a product lacking these described properties is not the claimed "feedstock," even if it contains the recited ingredients.

VI. Other Allegations

Indirect Infringement

The complaint explicitly alleges both induced and contributory infringement. It asserts inducement based on Defendants "actively encouraging others" (e.g., farmers) to use the accused products in an infringing manner. (Compl. ¶153). It alleges contributory infringement on the basis that Defendants sell a material component (the fertilizer formula) knowing it is especially adapted for an infringing use and is not a staple article of commerce. (Compl. ¶154).

Willful Infringement

While the complaint does not use the word "willful" in its patent infringement count, it alleges Defendants "actively, knowingly, and intentionally induced infringement." (Compl. ¶153). The overarching narrative, which centers on a former CEO with intimate knowledge of the Plaintiff’s technology and intellectual property, provides a strong factual basis for arguing that any infringement was undertaken with knowledge of the patent, a key element for a potential willfulness claim.

VII. Analyst’s Conclusion: Key Questions for the Case

  • A key evidentiary question will be one of chemical identity: Will discovery and testing confirm the complaint's allegation that the accused "Fusion/Rogue" products contain potassium formate and other "yield-assist constituents" within the specific compositional ranges recited in claim 14?
  • The case will likely involve a central question of infringement liability: As claim 14 is directed to "treated irrigation water"—a composition created by the end-user—the court will have to determine if Plaintiff can prove that Defendants, as sellers of the precursor feedstock, are liable for direct infringement, or if the case will turn on proving the heightened knowledge and intent requirements for induced or contributory infringement.
  • A core issue will be one of definitional scope: How will the court construe the term "additional yield-assist constituent(s)"? The outcome of this claim construction battle—whether the term is interpreted broadly to cover many standard nutrients or narrowly limited to the patent's specific examples—may determine whether the accused products fall within the scope of the patent.
