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

U.S. Patent No. 10,035,651 - "Storage Systems and Methods for Retrieving Units from a Storage System"

• Patent Identification: U.S. Patent No. 10,035,651, "Storage Systems and Methods for Retrieving Units from a Storage System," issued July 31, 2018 Compl. ¶36

The Invention Explained

• Problem Addressed: The patent's background describes the inefficiency of retrieving a "target bin" located deep within a vertical stack of containers in a high-density storage system. This requires a time-consuming "digging" operation where overlying bins must be moved one by one. '651 Patent, col. 4:25-30 '651 Patent, col. 5:1-7
• The Patented Solution: The invention proposes a system with two different types of independently movable robotic handling devices operating above the stacks. A first handling device is capable of lifting a plurality of non-target containers from a stack in a single operation, while a second handling device can then access and lift the single target container that has been exposed. '651 Patent, abstract '651 Patent, col. 5:32-42 This dual-robot approach is intended to significantly speed up the retrieval process. '651 Patent, col. 5:48-52
• Technical Importance: The use of a specialized multi-bin handling device directly addresses the "digging" bottleneck, a primary constraint on the throughput of grid-based AS/RS technology. '651 Patent, col. 5:43-52

Key Claims at a Glance

• The complaint identifies independent claims 1, 5, and 7 as being asserted by Ocado Compl. ¶38
• The essential elements of independent claim 1 include:
  • A frame containing a plurality of stacks of containers;
  • A top of the frame including rails arranged in a grid pattern;
  • At least one handling device configured for lifting at least one container from a stack;
  • The handling device including a body mounted on two sets of wheels for movement on the rails;
  • The body of the handling device including a substantially centrally located container receiving space with container lifting means.
• The complaint does not mention any dependent claims.

U.S. Patent No. 10,759,597 - "Robotic Picking Systems and Devices"

• Patent Identification: U.S. Patent No. 10,759,597, "Robotic Picking Systems and Devices," issued September 1, 2020 Compl. ¶44

The Invention Explained

• Problem Addressed: The patent background identifies that conventional AS/RS systems require containers to be transported to separate picking stations for items to be removed, which can cause delays and congestion. '597 Patent, col. 2:18-33
• The Patented Solution: The patent describes a robotic picking device that operates directly on the storage grid itself. The device is configured to move above the stacks, pick an individual inventory item from a container, and move that item to a different, predetermined container (such as a delivery tote), all without removing the source container from the grid area. '597 Patent, abstract '597 Patent, col. 2:34-47
• Technical Importance: This "on-grid picking" concept decentralizes the order fulfillment process, aiming to reduce bottlenecks at picking stations and improve overall system efficiency and speed. '597 Patent, col. 2:50-53

Key Claims at a Glance

• The complaint identifies independent claims 1, 11, and 24 as being asserted by Ocado Compl. ¶45
• The essential elements of independent claim 1 include:
  • A picking device for a grid-based storage system with containers located beneath tracks;
  • The picking device is adapted to move laterally on the tracks above the containers;
  • The picking device includes "picking means" to pick at least one inventory item from a container;
  • The picking device includes "means for moving" the item to a different predetermined container.
• The complaint does not mention any dependent claims.

III. The Accused Instrumentality

Product Identification

The accused instrumentality is Plaintiff's "Gridpicker" robotic fulfillment system Compl. ¶19

Functionality and Market Context

The complaint describes the Gridpicker as an AI-powered, end-to-end warehouse automation solution Compl. ¶4 A key characteristic alleged by the Plaintiff is that it operates within a "traditional warehouse rack-and-aisle layout" using standard shelving Compl. ¶20 Items are stored in trays called "totes" which rest on these shelves Compl. ¶20 To retrieve a tote not on the top shelf, a separate robot moves through the aisle, laterally pulls the tote from its shelf, and moves it to the top level for a picking robot to access Compl. ¶20 The complaint contrasts this with Ocado's system, which it describes as requiring a "grid of stacked containers" that are only addressable from the top Compl. ¶¶17-18 An image in the complaint shows multiple Gridpicker robots on a grid-like floor structure, with one robot positioned next to a shelving rack Compl. p. 5 The complaint positions the Gridpicker system as an innovative solution that avoids the high capital cost of rebuilding a warehouse, as it is compatible with existing rack-and-aisle infrastructure Compl. ¶4 Compl. ¶15

IV. Analysis of Infringement Allegations

As this is a complaint for declaratory judgment of non-infringement, the following charts summarize the Plaintiff's (Brightpick's) allegations as to why its product does not meet the claim limitations.

'651 Patent Infringement Allegations

Claim Element (from Independent Claim 1)	Alleged Non-Infringing Functionality	Complaint Citation	Patent Citation
a frame containing a plurality of stacks of containers	The Gridpicker system uses standard shelving in a traditional warehouse rack-and-aisle layout, with items resting on shelves rather than being stacked on top of each other.	¶41	col. 2:39-41

'597 Patent Infringement Allegations

Claim Element (from Independent Claims 1 & 24)	Alleged Non-Infringing Functionality	Complaint Citation	Patent Citation
movement of the device ... such that the picking device may be positioned above a predetermined container to pick the item (Claim 1)	The Gridpicker system picks from a position that is laterally offset from the tote, not from a position "above" the tote.	¶47	col. 10:25-29
lifting means for lifting at least one container from beneath a grid into the container receiving space during operation (Claim 24)	The Gridpicker system picks from a lateral position and does not perform a "lifting" of the tote "into the container receiving space."	¶49	col. 10:25-29

• Identified Points of Contention:
  • Scope Questions: A central dispute for the '651 Patent, and indeed for most of the patents-in-suit, will be the construction of the phrase "plurality of stacks of containers" Compl. ¶39 The case raises the question of whether this term, used in the context of directly-stacked bins, can be interpreted to read on a system where containers (totes) are placed on individual shelves within a traditional rack-and-aisle structure.
  • Technical Questions: For the '597 Patent, the analysis may focus on the operational differences between the systems. The complaint alleges its Gridpicker robots access totes laterally, while the patent describes a device "positioned above" a container to lift it '597 Patent, col. 21:48-49 Compl. ¶47 The question for the court will be whether the Gridpicker's lateral retrieval mechanism performs a function equivalent to the claimed "lifting means for lifting... from beneath a grid into the container receiving space" Compl. ¶48 The complaint includes an image of a Gridpicker robot next to a shelving unit, which may be used to argue this functional distinction Compl. p. 11

V. Key Claim Terms for Construction

• The Term: "a plurality of stacks of containers"

• Context and Importance: This term, or a close variant, appears in the independent claims of at least six of the seven patents-in-suit Compl. ¶39 Compl. ¶55 Compl. ¶63 Compl. ¶70 Compl. ¶84 '574 Patent, claim 1 Brightpick's primary non-infringement argument is that its system uses shelves, not "stacks." Therefore, the construction of this term will be dispositive for much of the case. Practitioners may focus on this term because it represents the core architectural difference alleged between the patented technology and the accused system.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The term "stack" is not explicitly defined in the '651 patent with a negative limitation that would expressly forbid the presence of shelves between containers. A party might argue that a vertical column of containers, even if separated by shelves, could still be considered a "stack" in a general sense.
  • Evidence for a Narrower Interpretation: The '651 patent specification repeatedly and consistently describes the architecture as "stackable containers, known as bins 10, are stacked on top of one another to form stacks 12" '651 Patent, col. 2:39-41 The figures, such as Figure 1 of the '651 patent, depict containers in direct vertical contact. This consistent description may support an interpretation that requires containers to be physically stacked on each other.

• The Term: "positioned above a predetermined container"

• Context and Importance: This term from the '597 patent is central to Brightpick's non-infringement argument for that patent. Brightpick alleges its robots access totes from a "laterally offset" position, not from "above" Compl. ¶47 The outcome of the infringement analysis for the '597 patent may depend on whether "above" requires direct vertical alignment (i.e., within the same X-Y footprint) or can have a broader meaning.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: A party could argue that "above" is a relative term and only requires the picking device to be at a higher Z-axis coordinate than the container, without a strict requirement for X-Y alignment.
  • Evidence for a Narrower Interpretation: The '597 patent's detailed description states "the lifting means 44 of the picking device 230 is placed over a bin 10 in a stack 12" ('597 Patent, col. 10:25-27, emphasis added). Figures 8c and 8d of the '597 patent, which are referenced in the complaint, depict the picking device directly over the bin it is engaging Compl. p. 10 This may support a narrower construction requiring direct vertical alignment.

VI. Other Allegations

• Indirect Infringement: The complaint makes general denials of contributory infringement and inducement for all asserted patents but does not provide specific facts for analysis, as its purpose is to seek a declaration of non-infringement Compl. ¶43 Compl. ¶51 Compl. ¶60 Compl. ¶67 Compl. ¶74 Compl. ¶81 Compl. ¶88
• Willful Infringement: The complaint does not allege willfulness but seeks a declaration of non-infringement, which, if granted, would preclude a finding of willfulness. The facts alleged in the complaint, specifically the receipt of a letter from Ocado's U.S. counsel on April 9, 2026, establish that Brightpick had pre-suit knowledge of the patents-in-suit Compl. ¶34 This fact would become central to a willfulness analysis if Brightpick were to be found liable for infringement.

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

• A core issue will be one of definitional scope: Can the term "plurality of stacks of containers," which appears throughout the asserted patents and is described in the specifications as containers resting directly on top of one another, be construed to cover the accused Gridpicker system, where containers rest on individual shelves in a traditional rack-and-aisle warehouse configuration?
• A second central question will be one of functional distinction: Does the Gridpicker system's use of separate robots for lateral tote retrieval from an aisle and subsequent picking from the top level represent a fundamentally different technical operation than the patented methods, which describe a single type of device operating "above" a grid to lift, move, and pick from containers?
• Finally, the case raises a procedural and competitive context question: To what extent will the history of conflict between the parties, including the ex parte injunction obtained by Ocado in Germany Compl. ¶¶27-28, influence the court's view of the dispute, particularly in relation to equitable considerations or potential remedies?
