II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 10,858,176 - "Portion Capsule Having An Identifier"
- Issued: December 8, 2020.
The Invention Explained
- Problem Addressed: The patent's background section notes that a wide variety of similar-looking coffee capsules are on the market. Using a capsule in a machine for which it was not designed could lead to "significant security issues and/or the coffee machine may be damaged" (Compl. ¶38; ’176 Patent, col. 1:17-21). Specific risks cited include compromising the brewing chamber's seal, resulting in the discharge of high-pressure hot water (’176 Patent, col. 8:18-23).
- The Patented Solution: The invention proposes placing an "identifier," such as a barcode, on the portion capsule. A machine with a barcode reader can then identify the capsule to confirm compatibility and automatically adapt brewing parameters like "the pressure, the temperature and/or the amount of water" to suit the specific beverage (’176 Patent, col. 5:60-61). This creates a system that is both safer and capable of producing a consistent, quality beverage tailored to the specific capsule used (Compl. ¶39).
- Technical Importance: This technology allows for the creation of a closed ecosystem, preventing the use of incompatible third-party capsules while also automating the brewing process for different types of beverages (e.g., espresso vs. a larger coffee) from a single machine (Compl. ¶39).
Key Claims at a Glance
- The complaint asserts independent claim 1 and dependent claims 2-3 and 10-14 (’176 Patent, col. 13:1-14:12; Compl. ¶52).
- Independent Claim 1 is a method claim with the essential elements:
- Providing an apparatus with a barcode reader.
- Inserting a first portion capsule with specific physical features and a first barcode.
- Reading the first barcode and controlling a first production process based on that reading.
- Performing brewing steps (piercing, sealing, introducing water).
- Unloading the first capsule.
- Inserting a second portion capsule with a second barcode different from the first.
- Reading the second barcode and controlling a second production process different from the first.
- Performing brewing steps for the second capsule.
U.S. Patent No. 10,858,177 - "Portion Capsule Having An Identifier"
- Issued: December 8, 2020.
The Invention Explained
- Problem Addressed: As with the related ’176 Patent, the invention addresses the problem of consumers using incompatible beverage pods, which can damage the brewing machine or create safety hazards for the user (Compl. ¶70; ’177 Patent, col. 1:17-21).
- The Patented Solution: The patent claims a complete beverage system comprising both the portion capsule and the beverage machine. The core of the solution is a machine with a detector that reads a barcode on the capsule and a pump that "is controlled to push water into the portion capsule only upon a determination that the read barcode agrees with a stored reference" (’177 Patent, Abstract). This creates an automated compatibility check that prevents the machine from operating with unauthorized capsules (’177 Patent, col. 2:11-14).
- Technical Importance: By claiming the system as a whole, the patent covers the physical apparatus that enforces the closed ecosystem, contrasting with the method claims of the ’176 Patent (Compl. ¶73).
Key Claims at a Glance
- The complaint asserts independent claim 1 and dependent claims 4 and 5 (’177 Patent, col. 13:50-14:48; Compl. ¶78).
- Independent Claim 1 is a system claim with the essential elements:
- A portion capsule with a foil lid, a cavity for beverage material, and a circumferential flange with a barcode on its bottom side.
- The capsule's base element has an electrically conductive section and radially/vertically oriented grooves and ribs.
- A beverage machine that includes:
- A barcode detector.
- A media chute to receive and support the capsule.
- A pump controlled to push water into the capsule only upon a determination that the read barcode agrees with a stored reference.
U.S. Patent No. 10,870,531 - "Portion Capsule Having An Identifier"
- Issued: December 22, 2020.
Technology Synopsis
The ’531 Patent claims a method of using a portion capsule in a machine. The method involves providing a machine with a barcode reader and pump, inserting a capsule with specific features (including a base element and/or lid made of metal and an electrically conductive section), piercing the lid, reading the barcode, and activating the pump to push heated water into the capsule only if the barcode matches a stored reference (Compl. ¶98; ’531 Patent, claim 1). This ensures both compatibility and correct brewing settings.
Asserted Claims
The complaint asserts independent claim 1 and several dependent claims (Compl. ¶104).
Accused Features
The accused features are the operational steps of the Nespresso Vertuo system, including the insertion of aluminum Vertuo pods, the machine's reading of the barcode on the pod, and the subsequent control of the brewing cycle based on the barcode information (Compl. ¶¶100-103).
III. The Accused Instrumentality
Product Identification
The accused instrumentalities are Defendants' "Vertuo Next, VertuoPlus, Evoluo, and Vertuo product lines," which include both single-serve beverage machines and their corresponding capsules ("Vertuo pods") (Compl. ¶14).
Functionality and Market Context
The complaint alleges that the Vertuo system employs "Centrifusion™ technology" and an "intelligent extraction system" that "recognizes, through barcode technology, each expertly designed coffee capsule" (Compl. ¶31). According to Nespresso's website, as cited in the complaint, "each Vertuo machine[] uses barcode recognition . . . The unique barcode on each capsule adjusts the flow and volume of water, temperature, infusion time and capsule rotation" (Compl. ¶45). The complaint highlights that Defendants have marketed this system as a "groundbreaking advancement" and one of the "most important Nespresso innovations in the past 25 years" (Compl. ¶¶31, 42). A screenshot from the Nespresso website states the "Vertuo technology reads the barcode on each capsule, automatically adjusting to the perfect settings" (Compl. ¶43).

Identified Points of Contention
- Scope Questions: The method claim of the ’176 Patent requires a sequence involving two different capsules. A potential point of contention is whether Plaintiff must prove that end-users perform this entire sequence of steps to establish direct infringement, or if an inducement theory based on the machine's inherent capability and instructions will be the primary focus.
- Technical Questions: For the ’177 Patent, the interpretation of the phrase "only upon a determination that the read barcode agrees with a stored reference" will be significant. The question for the court may be whether this requires the barcode match to be the sole and exclusive trigger for the pump, or if it functions as a necessary "gatekeeper" that must be satisfied before another action (e.g., a user pressing a button) can activate the pump. The complaint alleges the system uses the barcode to prevent use of third-party capsules, which suggests a gatekeeper function (Compl. ¶42).
V. Key Claim Terms for Construction
The Term: "only upon a determination that the read barcode agrees with a stored reference"
(from claim 1 of the ’177 Patent)
Context and Importance: The definition of this term is critical to the scope of the system claim. Its construction will determine whether the claim covers any system where barcode validation is a mandatory precondition for brewing, or if it is limited to systems where the barcode match is the sole, direct trigger for the pump's activation. Practitioners may focus on this term because it defines the precise logic of the machine's compatibility lock-out feature.
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The patent states that if the identifier matches the reference, the machine will be activated, and "Otherwise the coffee machine will not start operating" (’177 Patent, col. 2:12-14). This language could support a broader "gatekeeper" interpretation, where the match is a necessary condition precedent to any operation.
- Evidence for a Narrower Interpretation: The claim language "pump that is controlled to push water... only upon a determination" could be argued to require a direct causal link between the match and the pump activation, without intervening steps like a user command. A defendant may argue that if a user must still press a "brew" button after a successful barcode scan, the "only upon" condition is not met.
The Term: "a second production process being different than the first production process"
(from claim 1 of the ’176 Patent)
Context and Importance: This term is central to proving infringement of the full two-capsule method. The dispute may center on how "different" the two processes must be. The complaint alleges the Vertuo system adjusts multiple parameters like water volume, temperature, and rotation, which would constitute different processes (Compl. ¶49).
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The specification provides a non-exhaustive list of parameters that may be adapted, including "the pressure, the temperature and/or the amount of water" (’176 Patent, col. 5:60-61). This suggests that a change in any single brewing parameter could render the process "different."
- Evidence for a Narrower Interpretation: A defendant could argue that minor or trivial variations in brewing parameters do not constitute a "different" process and that a more substantial, qualitatively distinct change is required by the claim.
VI. Other Allegations
Indirect Infringement
The complaint alleges inducement of infringement for all patents, asserting that Defendants provide the accused products along with instructions, user manuals, and online videos that encourage and direct customers to use the systems in an infringing manner (Compl. ¶¶56, 82, 108).
Willful Infringement
The complaint alleges willfulness based on Defendants' alleged pre-suit knowledge of the application that led to the ’176 Patent since at least May 15, 2019 (Compl. ¶54). For all patents, the complaint itself is asserted as providing notice to support claims of post-suit willful infringement (Compl. ¶¶54, 80, 106).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of infringement theory and proof: For the method claims of the ’176 Patent, which require a sequence involving two different capsules, a key question is whether direct infringement by end-users can be sufficiently proven at scale, or if the case will depend primarily on a theory of indirect infringement based on the machine's capabilities and Defendants' instructions.
- A second central issue will be one of claim scope: The construction of the term "only upon" in the ’177 Patent's system claim will be pivotal. The case may turn on whether this term is interpreted broadly to mean a necessary "gatekeeper" check for compatibility, or narrowly to mean the barcode match is the sole and direct cause of the pump's activation.
- A third question will be evidentiary: The complaint relies heavily on Defendants' marketing materials to describe the accused functionality. A key aspect of the case will be the extent to which discovery into the Vertuo system's software and hardware reveals a technical implementation that maps directly onto the specific limitations of the asserted claims, such as the use of a "stored reference" and the precise logic for controlling the brewing process.
