Case Timeline

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

U.S. Patent No. 8,725,924 - "Information Backup System with Storing Mechanism and Method of Operation Thereof," issued May 13, 2014

The Invention Explained

• Problem Addressed: The patent describes the difficulty of backing up data from handheld devices like smart phones, which are prone to being lost, damaged, or replaced with different models that have incompatible communication interfaces (’924 Patent, col. 1:29-54).
• The Patented Solution: The invention proposes a system where a dedicated "host microcontroller" serves as the master controller for both a handheld device (e.g., a phone) and a separate mass storage device (e.g., a USB drive). This intermediary device supplies power to both ports and manages the data transfer between them, allowing for a direct backup from the phone to the storage drive without requiring a personal computer to orchestrate the process (’924 Patent, Abstract; col. 2:21-41; Fig. 10).
• Technical Importance: This architecture provides a method for backing up data from devices that typically function only as "slave" devices and cannot independently control another peripheral, simplifying the backup process for users of portable electronics (’924 Patent, col. 7:36-40).

Key Claims at a Glance

• The complaint asserts independent method Claim 1 (Compl. ¶16).
• Essential Elements of Claim 1:
  • supplying power to a first and second communication port via an internal power supply;
  • electrically connecting a host microcontroller to the first port for connecting a handheld device;
  • electrically connecting the host microcontroller to the second port for connecting a mass storage device;
  • wherein the host microcontroller functions as a host to both the first and second communication ports; and
  • transferring data between the two ports.
• The complaint reserves the right to assert additional claims (Compl. ¶15).

U.S. Patent No. 6,938,104 - "Removable Hard Drive Assembly, Computer with a Removable Hard Disk Drive, Method of Initializing and Operating a Removable Hard Drive," issued August 30, 2005

The Invention Explained

• Problem Addressed: The patent notes that standard internal computer hard drives are typically configured as "fixed" or non-removable devices. An operating system expects them to be permanently attached, and removing one while the computer is running ("hot-swapping") was not natively supported, unlike lower-capacity media like floppy disks (’104 Patent, col. 5:33-40).
• The Patented Solution: The invention describes a system with a programmable circuit board placed between a standard hard drive and the host computer. This circuit intercepts the drive's native identification data (its "ID buffer"), which marks it as a fixed device, and alters it to report to the host computer that the drive is a "removable media device." This technique "fools" the operating system into treating a conventional, high-capacity hard drive as a hot-swappable device (’104 Patent, Abstract; col. 4:16-23).
• Technical Importance: The technology enabled the convenient use of high-capacity, high-speed hard disk drives for portable, hot-swappable data storage, overcoming the capacity and speed limitations of other removable media available at the time (’104 Patent, col. 5:7-14).

Key Claims at a Glance

• The complaint asserts independent system Claim 9 (Compl. ¶26).
• Essential Elements of Claim 9:
  • a computer system with a standard drive bay, power supply, and an ATA-standard drive controller;
  • a drive assembly mounted in the bay, connected to the power/drive controller, with an opening;
  • a removable cartridge with a hard drive device, dimensioned to fit in the opening; and
  • a printed circuit board connected between the hard drive and the host's drive controller, programmed to modify the hard drive's identification to indicate to the host that it is a removable drive.
• The complaint reserves the right to assert additional claims (Compl. ¶25).

III. The Accused Instrumentality

Product Identification

The complaint names the "ORICO Backuper Type-C External Enclosure" and the "ORICO-OS800" as infringing products, as well as a general category of "hard disk enclosures, docking stations, and adapters" (Compl. ¶12, ¶17, ¶25).

Functionality and Market Context

• The "ORICO Backuper Type-C External Enclosure" is alleged to operate as an information backup system that connects to both a handheld device and a mass storage device, managing data transfers between them using an internal host microcontroller (Compl. ¶17).
• The "ORICO-OS800" is alleged to be a device that includes a drive bay for a removable hard drive cartridge and a printed circuit board that modifies the drive's identification to make it appear as a removable drive to a host system (Compl. ¶27).
• No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

’924 Patent Infringement Allegations

• Identified Points of Contention:
  • Technical Questions: A primary technical question is whether the accused enclosure's internal circuitry meets the definition of a "host microcontroller" that "function[s] as a host" to both the handheld device and the mass storage device simultaneously. The evidence will need to show that the device actively manages both downstream peripherals, rather than implementing a simpler data pass-through or switching function that might fall outside the claim's scope.

’104 Patent Infringement Allegations

• Identified Points of Contention:
  • Scope Questions: A likely dispute will concern whether the accused "ORICO-OS800" enclosure, by itself, constitutes a "computer system" as recited in the claim preamble, or whether it is merely a component of such a system.
  • Technical Questions: The central factual dispute will be whether the accused product's circuit board is "programmed to modify an identification of the hard drive device." Plaintiff will need to provide evidence that the product actively alters the identifying information of a standard, non-removable hard drive, rather than simply using a drive that is already configured as removable.

V. Key Claim Terms for Construction

’924 Patent: "host microcontroller"

• Context and Importance: This term is the technological heart of Claim 1. The infringement analysis depends entirely on whether the accused device's controller performs the functions of a "host microcontroller" as understood in the patent, specifically its ability to manage two downstream devices.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The patent refers to the component as a "specialized microprocessor" and connects it to the function of transferring data between two ports, which could support a construction covering any controller that achieves this end result (’924 Patent, col. 4:22-23, col. 11:46-48).
  • Evidence for a Narrower Interpretation: The specification also refers to a "USB host controller" and depicts a specific architecture where a controller 1018 explicitly manages downstream ports 1010 and 1012 (’924 Patent, col. 7:21-22; Fig. 10). This could support an argument that the term requires the specific capabilities of a formal USB host or a similar dedicated control architecture.

’104 Patent: "modify an identification of the hard drive device"

• Context and Importance: This phrase captures the core inventive concept of the ’104 patent. Infringement hinges on proving that the accused product performs this specific action of modification.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The claim language recites modifying "an identification," which a party could argue is broader than modifying a specific data structure. This could potentially cover any process that results in the host receiving an identification that marks the drive as removable, even if the original ID buffer is not directly altered.
  • Evidence for a Narrower Interpretation: The specification provides a detailed explanation of the modification process, stating that the electronics modify the drive's "ID buffer" by altering specific bits (e.g., Bit 7 of Word 0) to "indicate that the drive is removable" (’104 Patent, col. 5:1-6, col. 8:26-30). This detailed description could be used to argue that "modify" requires the specific act of reading and changing the contents of the drive's pre-existing ID buffer.

VI. Other Allegations

• Indirect Infringement: The complaint alleges that the Defendant induces infringement by providing the accused products to customers and end-users with the knowledge and intent that they will be used in an infringing manner (Compl. ¶18-20, ¶28-30). The complaint does not, however, cite specific instructional materials or marketing documents to support these allegations.
• Willful Infringement: Willfulness is alleged based on Defendant’s knowledge of the patents, with knowledge asserted to exist "at least as of the date of this Complaint" (Compl. ¶19, ¶29). This provides a basis for potential post-suit willfulness. The complaint also alleges willful blindness (Compl. ¶20, ¶30).

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

• A core issue will be one of functional operation: For the ’924 patent, the case will likely turn on whether the accused backup device’s internal controller performs the dual-host management role required by the term "host microcontroller," or if it employs a technologically distinct, simpler data-forwarding mechanism.
• A key evidentiary question will be one of technical proof: For the ’104 patent, the central issue will be whether the Plaintiff can produce evidence showing that the accused enclosure actively "modifies an identification" of a standard hard drive, as opposed to merely packaging a drive that is already configured by its original manufacturer as removable.
• A foundational dispute may be one of definitional scope: For the ’104 patent, the parties will likely contest whether an external hard drive enclosure can be considered a "computer system" as recited in Claim 9, raising a potentially case-dispositive question of claim construction.
