Frazer Industries LLC v. Eteros Technologies

I. Executive Summary and Procedural Information

• Parties & Counsel:
  • Plaintiff: Frazer Industries LLC (Washington)
  • Defendant: Eteros Technologies Inc. (Canada); Eteros Technologies USA, Inc. (Washington)
  • Plaintiff's Counsel: Baker IP PLLC; Ray Quinney & Nebeker P.C.
• Case Identification: 2:25-cv-00202, D. Utah, 07/28/2025
• Venue Allegations: Plaintiff alleges venue is proper in the District of Utah because Defendants have substantial, continuous, and systematic contacts with the district, including transacting business through a local retail partner, Moonlight Garden Supply in Salt Lake City.
• Core Dispute: Plaintiff alleges that Defendants' cannabis and hemp harvesting machines, known as "buckers," infringe a patent directed to systems and methods for mechanically separating cannabis leaves and buds from their stems.
• Technical Context: The technology relates to agricultural mechanization in the commercial cannabis industry, aiming to automate the labor-intensive process of stripping harvested plants to improve efficiency and maintain product quality.
• Key Procedural History: The complaint alleges that Defendants had pre-suit knowledge of the patent family as early as October 2018. It also notes a conversation at a November 2018 conference where the former owner of one of Defendants' brands allegedly acknowledged the product was a "copy." The asserted patent underwent a reexamination that amended some claims not asserted in the complaint. The complaint also states that Defendant Eteros USA requested an ex parte reexamination of the patent-in-suit on July 16, 2024. This history suggests a long-standing awareness of the technology and may be used to support allegations of willfulness.

Case Timeline

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

• Patent Identification: U.S. Patent No. 11,766,066, "SYSTEMS AND METHODS FOR MEDICINAL CANNABIS HARVESTING," issued September 26, 2023.

• The Invention Explained:

  • Problem Addressed: The patent's background section describes the growing and harvesting of cannabis as a multi-step process traditionally done by hand ʼ066 Patent, col. 1:28-30 It notes that manual separation of desirable leaves and buds from undesirable stems is inefficient, and that harvesting equipment from other crop types has failed to work effectively for cannabis due to the plant's unique structure ʼ066 Patent, col. 1:33-36 '066 Patent, col. 1:50-59
  • The Patented Solution: The invention is a mechanical harvesting system designed specifically for cannabis stems ʼ066 Patent, abstract As illustrated in the patent's figures, the system uses two counter-rotating cylindrical members (rollers) to create a "pinch region" that grabs a cannabis stem and pulls it through an orifice in a "die member" (plate) ʼ066 Patent, Fig. 12A-B This action strips the leaves and buds from the stem, which then fall into a collection bin ʼ066 Patent, col. 8:35-38 A critical aspect of the design is the close proximity of the orifices to the pinch region, which the patent teaches is necessary for the proper harvesting of cannabis ʼ066 Patent, col. 10:30-33
  • Technical Importance: The invention provides an automated solution specifically engineered for the physical properties of cannabis plants, addressing a key bottleneck in the commercial harvesting process. ʼ066 Patent, col. 2:21-24

• Key Claims at a Glance:

  • The complaint asserts infringement of at least independent claim 1 Compl. ¶19
  • The essential elements of independent claim 1 are:
    • A frame member;
    • A die member coupled to the frame, which includes a plate with a plurality of orifices;
    • A first rotating cylindrical member coupled to the frame;
    • A second rotating cylindrical member coupled to the frame;
    • The two rotating members are in a "substantially vertical configuration" that defines a "pinch region" where their surfaces are in closest proximity;
    • A rotation system with a motor and power source; and
    • The plurality of orifices are disposed "within six inches of the pinch region." Compl. ¶17

III. The Accused Instrumentality

• Product Identification: The complaint accuses the "Eteros Buckers," which include the BUCKMASTER, BUCKMASTER PRO, and MBX BUCKER models Compl. ¶18
• Functionality and Market Context: The complaint alleges these are commercial machines for harvesting cannabis and hemp Compl. ¶18 It states their function is to "efficiently and carefully remove the buds from their stems" and "gently removes cannabis and hemp flowers from their stems" Compl. ¶20 The complaint includes annotated diagrams from Defendants' websites that identify key components such as a "roller assembly," "bucking plate" (die plate), and "motor assembly," which allegedly correspond to the elements of the patented system Compl. ¶18 An image from a product page shows an exploded diagram of the Buckmaster Pro, identifying a "roller assembly" containing rubber rollers and "bucking plates" Compl. p. 8

IV. Analysis of Infringement Allegations

'066 Patent Infringement Allegations

• Identified Points of Contention:
  • Factual Question: The complaint's allegation for the final limitation-that the orifices are "within six inches of the pinch region"-is made "on information and belief" based on "publicly available videos and visual inspections" Compl. ¶27 This raises the question of what specific evidence Plaintiff will produce to prove this critical geometric relationship, as it appears to be a central part of the inventive concept.
  • Scope Question: The claim requires a "substantially vertical configuration" for the rotating members. While the complaint's visuals appear to show a stacked orientation Compl. ¶25, a potential point of dispute could be the definition of "substantially." The defense may argue that any deviation from a perfectly vertical alignment of the rollers' axes is legally significant.

V. Key Claim Terms for Construction

• The Term: "pinch region"

• Context and Importance: This term defines the location from which the critical "six inches" distance is measured. Its construction is vital to determining whether the accused products meet the final, and perhaps most significant, limitation of claim 1.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The patent specification defines it as "a region of closest proximity between the first and second circumferential surfaces" '066 Patent, col. 10:11-14 This functional language may support a broader interpretation that does not require direct physical contact between the rollers.
  • Evidence for a Narrower Interpretation: The patent also notes the region "may include a coupling between the first and second circumferential surfaces" '066 Patent, col. 10:25-27, which could be argued to imply physical contact. A defendant may point to specific embodiments to argue for a narrower, more structurally defined region.

• The Term: "within six inches of the pinch region"

• Context and Importance: This is a specific, quantitative limitation that distinguishes the invention from prior art and is a cornerstone of the infringement allegation. Practitioners may focus on this term because proving it is a simple matter of measurement, and failure to do so is fatal to the infringement claim.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: A plaintiff would argue the term should be given its plain and ordinary meaning: the distance from any part of any orifice to the closest part of the pinch region must be less than or equal to six inches.
  • Evidence for a Narrower Interpretation: A defendant could argue that the measurement must be made in a specific way not explicitly defined (e.g., from the center of the orifice, or only in a certain plane). The patent states that extensive testing "concluded that the distance to the pinch region 492 must be under six inches to function properly for harvesting of cannabis with an optimal value of approximately two inches" '066 Patent, col. 10:30-35, language which a defendant might use to argue that "within six inches" really means a much smaller, optimal distance.

VI. Other Allegations

• Indirect Infringement: The complaint alleges both induced and contributory infringement. It claims Defendants induce infringement by selling the Eteros Buckers with the knowledge and intent that customers will use them in an infringing manner Compl. ¶31 Compl. ¶35 It further alleges contributory infringement on the basis that the accused products are especially made for practicing the invention and are not staple articles of commerce with substantial non-infringing uses Compl. ¶38 Compl. ¶49
• Willful Infringement: The complaint makes specific allegations to support willfulness. It claims Defendants had knowledge of the patent's underlying application as early as October 2018 via a notification letter Compl. ¶28 It further alleges that at a November 2018 conference, the CEO of Frazer had a conversation with the "former owner of Triminator," who acknowledged the accused product was a "copy" of a Frazer product and would "likely infringe" the resulting patent Compl. ¶29 Defendants' own action of requesting reexamination of the patent in 2024 is also cited as evidence of knowledge Compl. ¶30

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

• A central evidentiary question will be one of measurement: Can the Plaintiff prove, with reliable evidence, that the accused products' stripping orifices are located "within six inches of the pinch region" as strictly required by Claim 1, especially given that this allegation is currently pleaded on "information and belief"?
• A key legal question will be one of willfulness: In light of the highly specific allegations of pre-suit knowledge dating to 2018, including an alleged admission of copying, can the Defendants successfully argue they had a good-faith belief of non-infringement or invalidity, or will the case turn on the extent of enhanced damages for willful infringement?
• A core issue of claim construction will be one of definitional precision: How will the court define the boundaries of the "pinch region"? A construction requiring direct physical contact between the rotating members, versus one allowing for a defined gap, could be outcome-determinative for the "within six inches" infringement analysis.
