• Patent Identification: U.S. Patent No. 10,507,407, "Methods to reduce chlorophyll co-extraction through extraction of select moieties essential oils and aromatic isolates," issued December 17, 2019.

The Invention Explained

• Problem Addressed: The patent's background describes prior art methods for cannabis extraction, such as those using hydrocarbons (e.g., butane) or supercritical CO2, as facing significant drawbacks ʻ407 Patent, col. 1:19-40 Hydrocarbon methods are noted for their volatility and the dangers associated with their use, while supercritical CO2 extraction is described as expensive and inefficient at separating desired compounds from undesired ones like plant lipids ʻ407 Patent, col. 1:26-40
• The Patented Solution: The invention proposes a method using a super-cooled solvent, specifically 100% grain ethanol, to extract cannabinoids and terpenes ʻ407 Patent, col. 2:4-5 By lowering the temperature of the solvent and the plant substrate to a range of -30°C to -50°C, the process selectively dissolves the desired compounds while leaving behind undesired waxes and chlorophyll, which have lower solubility at such cold temperatures ʻ407 Patent, col. 2:6-9 '407 Patent, col. 3:4-6 This is intended to produce a cleaner initial extract and reduce the need for extensive post-processing ʻ407 Patent, col. 1:58-65
• Technical Importance: The patented method aims to provide a safer, more efficient, and commercially viable process for producing high-purity cannabis extracts compared to the flammable hydrocarbon or capital-intensive supercritical CO2 methods prevalent at the time ʻ407 Patent, col. 1:58-65

Key Claims at a Glance

• The complaint asserts infringement of at least independent claim 1 Compl. ¶40
• The essential elements of independent claim 1 are:
  • (i) pre-processing comprising lowering the temperature of a solvent to a range of -30 degrees C. and -50 degrees C.,
  • (ii) contacting at -30 degrees C. to -50 degrees C. wherein there is a contacting time between the plant substrate and the solvent to create an emulsion,
  • (iii) evaporating for reduction of the emulsion by means of atmospheric evaporation of the solvent,
  • (iv) recovering for recovery of the solvent from the emulsion,
  • (v) purging whereby a resultory extract is substantially free of any lipids and chlorophyll.
• The complaint alleges infringement of "one or more claims" of the patent, reserving the right to assert additional claims, including dependent claims Compl. ¶41

U.S. Patent No. 10,814,248 - "Methods to reduce chlorophyll co-extraction through extraction of select moieties essential oils and aromatic isolates"

• Patent Identification: U.S. Patent No. 10,814,248, "Methods to reduce chlorophyll co-extraction through extraction of select moieties essential oils and aromatic isolates," issued October 27, 2020.

The Invention Explained

• Problem Addressed: Similar to its parent, the '248 Patent addresses the safety, cost, and purity issues associated with prior art cannabis extraction techniques using hydrocarbons or supercritical fluids ʻ248 Patent, col. 1:30-56
• The Patented Solution: The '248 Patent also discloses a cold extraction process but expands upon the solvent composition. While still focused on a low-temperature extraction between -30°C and -50°C, this patent explicitly claims the use of solvent mixtures, such as 95% ethanol with 5% of another non-ethanol solvent, or alternative solvents like heptane, hexane, and isopropyl alcohol ʻ248 Patent, col. 2:50-56 '248 Patent, claim 1 The process steps of contacting, evaporating, recovering, and purging remain central to the method ʻ248 Patent, col. 2:40-49
• Technical Importance: By broadening the range of applicable solvents beyond pure ethanol, the invention provides processors with greater flexibility to optimize their extraction method based on cost, availability, and the specific profile of compounds being targeted ʻ248 Patent, col. 2:57-65

Key Claims at a Glance

• Identified Points of Contention:
  • Scope Question: The complaint alleges the "atmospheric evaporation" step is performed using an evaporator that "retains and recaptures" the solvent Compl. ¶32 This raises the question of whether a closed or semi-closed recapture system falls within the scope of "atmospheric evaporation," which a court may be asked to construe as being limited to open-air evaporation.
  • Evidentiary Question: The claims require the resulting extract to be "substantially free of any lipids and chlorophyll." The complaint asserts this based on the final product's quality and characteristics Compl. ¶31 Compl. ¶37 The factual basis for this assertion and the degree of "freeness" required will be a central point of evidence and argument.
  • Factual Question: The complaint alleges operation in the claimed -30°C to -50°C range Compl. ¶29, while also mentioning temperatures "below -40C" Compl. ¶24 Proving that the accused process consistently operates within the precise temperature window recited in the claims will be critical for the plaintiff's infringement case.

V. Key Claim Terms for Construction

• The Term: "substantially free of any lipids and chlorophyll"

• Context and Importance: This term defines the required purity of the final product and is a critical limitation for infringement. Its construction will determine the quantitative or qualitative standard against which the accused process's output is measured. Practitioners may focus on this term because its ambiguity could be a key non-infringement argument if the defendant's extract contains more than a de minimis amount of these impurities.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The body of the claims and specification does not provide a precise numerical definition, which may support a more flexible, qualitative interpretation (e.g., a noticeable reduction compared to warmer extraction methods). The term "substantially" itself suggests a standard of approximation rather than absolute purity.
  • Evidence for a Narrower Interpretation: The abstract of the '407 Patent states that the method provides an extract "with a concentration of chlorophyll that is below 1%" ʻ407 Patent, abstract A defendant may argue this statement provides a concrete, quantitative ceiling for what "substantially free" means, at least with respect to chlorophyll.

• The Term: "atmospheric evaporation of the solvent"

• Context and Importance: The definition of this term is central to whether the accused process, which allegedly uses a closed-loop evaporator to recapture solvent Compl. ¶32, meets this claim limitation. If "atmospheric" is interpreted narrowly, it could provide a straightforward non-infringement defense.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: A party may argue that "atmospheric" refers to the pressure conditions of the evaporation (i.e., not under vacuum or elevated pressure), regardless of whether the vapor is vented or captured. The specification introduces the step simply as "atmospheric evaporation of the solvent" without further limitation ʻ407 Patent, col. 2:19-21
  • Evidence for a Narrower Interpretation: The specification discusses a "solvent recovery step which can be accomplished via simple distillation or a rotary evaporator apparatus" separately from the evaporation step ʻ407 Patent, col. 2:21-23 A party could argue this distinction implies that "atmospheric evaporation" is a distinct, simpler process (e.g., open-air) and that using a "rotary evaporator" or similar recapture device falls under the separate "solvent recovery" step, not the "evaporation" step.

VI. Other Allegations

• Willful Infringement: The complaint alleges that Defendant's infringement of the '407 and '248 Patents has been willful, meriting increased damages Compl. ¶44 Compl. ¶50 The basis for this allegation is tied to notice of the patents provided by the lawsuit itself, with willfulness alleged to have begun "since at least the date of the filing of this complaint" Compl. ¶44 Compl. ¶50 The complaint does not allege pre-suit knowledge.

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

• A core issue will be one of definitional scope: can the claim term "substantially free of any lipids and chlorophyll" be met by an extract that shows a reduction in such impurities, or does the patent's abstract implicitly set a quantitative threshold (e.g., "below 1% chlorophyll") that the accused product must satisfy?
• A second key issue will be a technical and legal distinction: does the accused process, which allegedly uses an "evaporator which retains and recaptures" solvent, perform "atmospheric evaporation" as required by the claims, or is that a fundamentally different operation that falls outside the claim scope?
• A third central question will be one of evidentiary proof: beyond the narrative allegations, what specific, factual evidence can Plaintiff provide to establish that Defendant's extraction method operates within the precise temperature ranges recited in the claims and that the resulting commercial products consistently meet the claimed purity standard?
