MPL Brands NV, Inc v. Buzzballz, LLC
I. Executive Summary and Procedural Information
- Parties & Counsel:
- Plaintiff: MPL Brands NV, Inc. d/b/a Patco Brands (Nevada)
- Defendant: BuzzBallz, LLC (Texas)
- Plaintiff’s Counsel: Perkins Coie LLP
- Case Identification: 3:24-cv-01282, N.D. Cal., 03/29/2024
- Venue Allegations: Plaintiff alleges venue is proper in the Northern District of California because its headquarters is located in the district, a substantial part of the events giving rise to the claim occurred there, and its accused products were designed, developed, and stored in the forum.
- Core Dispute: Plaintiff MPL Brands seeks a declaratory judgment that its "Big Sipz" line of ready-to-drink cocktails does not infringe two patents owned by Defendant BuzzBallz related to the specific geometric shape of beverage containers.
- Technical Context: The lawsuit concerns container design in the competitive ready-to-drink alcoholic beverage market, where distinctive packaging is a key element of branding and market differentiation.
- Key Procedural History: This declaratory judgment action follows prior litigation between the parties. Defendant previously sued Plaintiff in the Western District of Texas for infringement of one of the patents-in-suit (the ’904 patent) but later amended its complaint to drop the infringement claim. Shortly after the second patent-in-suit (the ’441 patent) issued, Defendant filed a new lawsuit in the District of Nevada asserting it against Plaintiff. The complaint alleges that Defendant engaged in improper prosecution tactics, including dropping key limitations from parent patents to draft new claims that would specifically read on Plaintiff's existing products.

II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 11,738,904 - "Container"
- Patent Identification: U.S. Patent No. 11,738,904, titled "Container", issued August 29, 2023.
The Invention Explained
- Problem Addressed: The patent's background notes that while metal containers with easy-open lids are popular, metal is difficult and expensive to mold into novel shapes, limiting design options. Plastic, in contrast, is easily molded into various attractive shapes. (’904 Patent, col. 1:24-39).
- The Patented Solution: The invention combines a molded plastic container body with a conventional metal easy-open lid, seeking the design flexibility of plastic and the consumer familiarity of a "pop top." The patent describes a specific container geometry, including a body shaped like a "truncated spherical body," and claims a "stemless" configuration where the lower part of the container wall is wider than the container's base. (’904 Patent, col. 2:26-29; col. 4:32-39).
- Technical Importance: This hybrid approach allows for the creation of beverage containers with more distinctive, non-traditional silhouettes than typical cylindrical cans, which can enhance product appeal, while using a standard, inexpensive lid mechanism. (’904 Patent, col. 1:34-39).
Key Claims at a Glance
- The complaint focuses on independent claim 1. (Compl. ¶19).
- Essential elements of claim 1 include:
- A container body made of resin and a lid made of metal.
- A container body comprising a side wall and a "horizontally-extending portion" (the base).
- The opening at the top is narrower than the middle of the container body.
- The base is also narrower than the middle of the container body.
- A "lower portion" of the side wall extends from the middle to the base and is "greater in diameter along its entirety than the horizontally-extending portion, including the bottom, thereby rendering the container body stemless."
- The complaint does not explicitly reserve the right to assert dependent claims but states that "All claims of the '904 patent" require the "stemless" limitation. (Compl. ¶21).
U.S. Patent No. 11,932,441 - "Container"
- Patent Identification: U.S. Patent No. 11,932,441, titled "Container", issued March 19, 2024.
The Invention Explained
- Problem Addressed: The patent identifies the same problem as the ’904 patent: the difficulty of creating unique container shapes using traditional metal-forming processes. (’441 Patent, col. 1:28-34).
- The Patented Solution: Like the ’904 patent, the invention is a container with a molded plastic body and a metal lid. The claims of the ’441 patent also recite a "stemless" geometry but add further detail, defining specific angular relationships between the upper, middle, and lower portions of the container sidewall relative to the base. (’441 Patent, col. 4:20-27; col. 5:44-64).
- Technical Importance: This invention also seeks to enable unique container shapes for market differentiation while using a standard lid. (’441 Patent, col. 1:34-39).
Key Claims at a Glance
- The complaint focuses on independent claim 1. (Compl. ¶2).
- Essential elements of claim 1 include:
- A container body made of resin and a lid made of metal.
- A container body comprising a side wall and a "base portion."
- The base portion contains an upwardly-extending depression.
- A "lower portion" of the side wall extends from the middle to the base and is "greater in diameter along its entirety than the base portion, including the bottom, thereby rendering the container body stemless."
- The upper, middle, and lower portions of the side wall define specific acute, second, and obtuse angles, respectively, relative to the base.
- The complaint states that "All claims of the '441 patent" require the "stemless" limitation. (Compl. ¶6).
III. The Accused Instrumentality
Product Identification
- Plaintiff's "Big Sipz" ready-to-drink alcoholic cocktail products. (Compl. ¶16).
Functionality and Market Context
- The complaint alleges that Plaintiff produces ready-to-drink cocktails packaged in a can, similar to the Defendant. (Compl. ¶¶16, 18). The core of Plaintiff's non-infringement argument is that the shape of its Big Sipz container is factually different from the shape required by the patent claims. (Compl. ¶¶26-28). Specifically, Plaintiff alleges its products do not have the claimed "stemless" geometry. (Compl. ¶¶10-14, p.15). The complaint further alleges that Plaintiff intentionally designed its products to avoid the claims of Defendant's earlier patents, which required a "truncated spherical shape"—a limitation allegedly removed from the patents-in-suit. (Compl. ¶¶7-9, p.9). No probative visual evidence provided in complaint.
IV. Analysis of Infringement Allegations
’904 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Non-Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| wherein a lower portion of the container side wall extends downwardly from the middle portion of the container side wall to the horizontally-extending portion of the container body, said lower portion being greater in diameter along its entirety than the horizontally-extending portion, including the bottom, thereby rendering the container body stemless. | The complaint alleges that the container for Plaintiff's Big Sipz products does not satisfy this geometric limitation. | ¶¶26-3, p.10-11 | col. 4:32-39 |
’441 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Non-Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| wherein a lower portion of the container side wall extends downwardly from the middle portion of the container side wall to the base portion of the container body, the lower portion along its entirety being greater in diameter than the base portion, including the bottom, thereby rendering the container body stemless. | The complaint alleges that the container for Plaintiff's Big Sipz products does not satisfy this geometric limitation. | ¶¶10-14, p.15 | col. 4:20-27 |
Identified Points of Contention
- Scope Questions: A primary issue will be the proper construction of the "stemless" limitation. The complaint alleges that this term was adopted after Defendant removed language from parent patents requiring a "truncated spherical shape." (Compl. ¶¶25-27, p.5). This raises the question of whether the term "stemless" should be construed narrowly in light of the specification's embodiments (e.g., Fig. 1) and the prosecution history, or whether its plain meaning as defined in the claim (lower portion wider than base) should control.
- Technical Questions: The factual dispute will concern the actual geometry of the Big Sipz container. The case will likely require detailed measurements and expert analysis to determine if the accused container's "lower portion" is, in fact, "greater in diameter along its entirety" than its base portion.
- Prosecution History Questions: The complaint heavily relies on the prosecution history, alleging that Defendant improperly dropped limitations from parent patents to ensnare Plaintiff's products. (Compl. ¶¶12-14, p.12). This suggests that prosecution history estoppel and arguments related to prosecution disclaimer may be central to limiting the scope of the claims.
V. Key Claim Terms for Construction
- The Term: "rendering the container body stemless"
- Context and Importance: This phrase, present in the asserted independent claims of both patents, is identified in the complaint as the dispositive limitation that Plaintiff's products do not meet. (Compl. ¶26, p.10; ¶10, p.15). The definition of this term is therefore critical to the infringement analysis. Practitioners may focus on this term because the complaint alleges it was added to later-filed applications to capture a competitor's product while abandoning language ("truncated spherical shape") from parent patents that the competitor's product allegedly avoided. (Compl. ¶¶8-9, p.9).
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: A party may argue that the claim itself provides the complete definition: a container is "stemless" if its lower portion's diameter is greater along its entire length than the diameter of its base. (’904 Patent, col. 4:32-39). This interpretation would not depend on the overall shape (e.g., spherical vs. cylindrical) of the container.
- Evidence for a Narrower Interpretation: The specification repeatedly refers to the container body being shaped as a "truncated spherical body." (’904 Patent, col. 2:27-28). A party may argue that "stemless" must be interpreted in this context, limiting its application to containers that are generally rounded or spherical, as depicted in figures like Figure 1 of the patents. The prosecution history, particularly the alleged strategic removal of the "truncated spherical shape" limitation, may be presented as evidence that the patentee was attempting to broaden the claims beyond the original invention, which could support a narrower construction. (Compl. ¶11, p.11).
VI. Other Allegations
- Exceptional Case Allegations: The complaint does not contain a formal willfulness count. However, Plaintiff requests that the case be deemed "exceptional" under 35 U.S.C. § 285, entitling it to attorneys' fees. (Compl., Request for Relief, p.15). The basis for this request is the allegation that Defendant's infringement claims are "objectively baseless, bad faith, and false" and pursued for anticompetitive purposes, pointing to Defendant's withdrawal of its ’904 patent claim in prior litigation after receiving a non-infringement letter from Plaintiff. (Compl. ¶¶5-6, p.2; ¶18, p.9).
- Unfair Competition and Inequitable Conduct: Plaintiff brings a cause of action for unfair competition under California law, which is predicated on allegations that would typically support an inequitable conduct defense in patent law. (Compl. ¶¶11-28, p.11-14). Plaintiff alleges Defendant violated its duty of candor to the USPTO by (1) improperly adding new matter (a specific volume limitation) to an application to gain an earlier priority date (Compl. ¶¶3-7, p.13); (2) deliberately removing material limitations from parent patents to target Plaintiff's products (Compl. ¶¶12-14, p.12); and (3) failing to disclose its own commercial products and a relevant patent publication as material prior art during prosecution. (Compl. ¶¶17-25, p.13).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of claim scope and prosecution history: Will the court construe the term "stemless" based solely on the geometric definition provided in the claim, or will it be narrowed by the specification's disclosure of a "truncated spherical body" and the patentee's alleged strategic decision to remove that explicit language from the claims during prosecution?
- A key evidentiary question will be one of factual comparison: Based on the court's construction of the claims, do the precise physical measurements of Plaintiff's "Big Sipz" containers meet the "stemless" limitation, or is there a clear geometric mismatch as the complaint alleges?
- A dispositive threshold question will be the viability of Plaintiff's inequitable conduct theory: Does the evidence support the allegations that the patentee intentionally misled the USPTO by adding new matter, removing limitations to ensnare a competitor, and withholding material prior art? A finding of such conduct could render the patents unenforceable and support the unfair competition claim.
