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

U.S. Patent No. 9,307,014 - Supplemental capacity unit for portable wireless devices, issued April 5, 2016

The Invention Explained

• Problem Addressed: The patent asserts that portable wireless devices like tablets, while popular, lack the processing, memory, and storage capacities of traditional personal computers and laptops, preventing them from running full-featured software applications for tasks like CAD, complex gaming, or large-scale data analysis (’014 Patent, col. 1:36-61).
• The Patented Solution: The invention is a physical "supplemental capacity unit" that wirelessly connects to a portable device (’014 Patent, Fig. 1). This external unit contains its own processor, memory, and storage, and runs a "communication software program" that allows the portable device to offload computationally intensive tasks to the unit (’014 Patent, col. 2:21-44). The portable device effectively becomes a "virtual window" for operations being performed on the more powerful external unit, thereby overcoming its own hardware limitations (’014 Patent, col. 5:6-9).
• Technical Importance: The described approach seeks to bridge the gap between mobile convenience and desktop computing power, allowing users to perform resource-intensive tasks on portable devices that would otherwise be unable to support them.

Key Claims at a Glance

• The complaint asserts at least independent claim 1 (Compl. ¶11).
• Independent Claim 1: The essential elements include:
  • A supplemental capacity unit for at least one portable wireless device, comprising:
  • an electronic control board having wireless communication and at least one connection port,
  • the connection port being capable of interfacing with an additional device to increase computational power for computer aided design, gaming, and scientific calculation,
  • a communication software program accessible by the electronic control board and installed on the portable device,
  • the software enabling the portable device to use the computing power of the electronic control board,
  • the electronic control board providing a specified increase in floating point performance relative to the portable device.
• The complaint does not explicitly reserve the right to assert other claims but refers generally to "one or more claims" (’014 Patent, Compl. ¶11).

III. The Accused Instrumentality

Product Identification

The complaint names "AMD's Radeon Software Adrenalin" as the "Exemplary AMD Product" (Compl. ¶11).

Functionality and Market Context

The complaint does not describe the specific functionality of the accused software. It is identified only by its product name (Compl. ¶11). The complaint contains no allegations regarding the product's specific market position or commercial importance beyond the general allegation of infringement through making, using, selling, and importing the product (Compl. ¶11).

IV. Analysis of Infringement Allegations

The complaint alleges that it provides claim charts comparing the asserted claims to the accused products in an Exhibit 2, which is incorporated by reference (Compl. ¶17-18). However, this exhibit was not included with the public-facing complaint document. As a result, a detailed, element-by-element analysis of Plaintiff's infringement theory is not possible based on the provided filings.

The complaint’s narrative theory of infringement is stated at a high level. It alleges that Defendant directly infringes "at least exemplary claims 1 of the ’014 Patent" by "making, using, offering to sell, selling and/or importing, without limitation, at least AMD's Radeon Software Adrenalin" (Compl. ¶11). It further alleges direct infringement through internal testing and use of the products by Defendant's employees (Compl. ¶12). Without the accompanying claim charts, the specific manner in which the accused software is alleged to meet the limitations of a claimed physical "unit" is not detailed in the complaint.

No probative visual evidence provided in complaint.

V. Key Claim Terms for Construction

The central dispute may revolve around whether claims directed to a physical hardware "unit" can read on the accused software product.

• Term: "supplemental capacity unit"

  • Context and Importance: This term appears in the preamble of claim 1 and describes the invention as a whole. The construction of this term is critical because the patent repeatedly describes the "unit" as a physical hardware device (e.g., a "housing" containing an "electronic control board") while the accused product is software. Practitioners may focus on whether this term limits the claim to a physical apparatus or if it can be construed more broadly to cover a system created by software running on general-purpose hardware.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The claims use functional language, defining the "unit" by what it does (e.g., "provides an increase in floating point performance") rather than solely by its physical structure (’014 Patent, col. 6:29-39). Plaintiff may argue this functional definition is met by the accused software when it orchestrates a computer's hardware to perform the claimed functions.
    • Evidence for a Narrower Interpretation: The specification consistently describes the invention as a discrete physical object. The summary states the unit "preferably includes a housing, an electronic control board, a hard drive..." (’014 Patent, col. 2:26-30). The figures, such as Figure 7, explicitly depict a physical enclosure containing distinct hardware components like an electronic control board (12), hard drive (14), and power supply (22), which could support a narrower, purely physical interpretation.

• Term: "electronic control board"

  • Context and Importance: This is a core structural element of claim 1. The infringement analysis will depend on whether this term can describe a standard computer's motherboard or graphics card when running the accused "Radeon Software Adrenalin," or if it is limited to the specific, dedicated board of the patented external unit.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The patent does not define the term with particularity, stating only that it is "preferably microprocessor based" (’014 Patent, col. 4:8-9). This lack of a specific structural definition may leave room for an argument that any microprocessor-based board performing the claimed functions meets the limitation.
    • Evidence for a Narrower Interpretation: The detailed description and Figure 7 show the "electronic control board" (12) as a specific component contained within the housing (10) of the "supplemental capacity unit" (1), separate and distinct from the portable wireless device it communicates with (’014 Patent, col. 4:6-9; Fig. 7). This context suggests the term refers to the dedicated hardware of the external unit, not the pre-existing hardware of a general-purpose computer.

VI. Other Allegations

• Indirect Infringement: The complaint alleges both induced and contributory infringement. For inducement, it alleges Defendant sells the accused products and distributes "product literature and website materials" that instruct end users to use the products in an infringing manner (Compl. ¶14-15). For contributory infringement, it alleges the accused products are not staple articles of commerce suitable for substantial noninfringing use (Compl. ¶16).
• Willful Infringement: Willfulness is not explicitly pleaded as a separate count, but the complaint alleges that its filing constitutes "actual knowledge" and that Defendant's continued infringement is therefore knowing and intentional (Compl. ¶13-14). The prayer for relief requests that the case be declared exceptional under 35 U.S.C. § 285 (Compl. ¶D.i).

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

The complaint, as filed, presents several fundamental questions that will likely define the litigation.

• A core issue will be one of definitional scope: can the claim terms "supplemental capacity unit" and "electronic control board", which are described in the patent specification as physical hardware components in a standalone external device, be construed to read on the accused "Radeon Software Adrenalin," which is a software product that runs on a user's existing computer hardware?
• A second key issue will be evidentiary: given the absence of the referenced claim charts in the complaint, a central question will be what specific facts and evidence Plaintiff will proffer to support its allegation that the accused software practices each element of the asserted claims, particularly the structural limitations.
• Finally, the case may turn on the question of divided infringement: since the claims require both the "supplemental capacity unit" and a "portable wireless device" on which a "communication software program" is installed, the court will need to determine whether AMD's actions alone meet all claim limitations or if the actions of a third-party end-user must be attributed to AMD for a finding of direct infringement.
