II. Technology and Patent(s)-in-Suit Analysis
- Patent Identification: U.S. Patent No. 6,446,111, Method and Apparatus for Client-Server Communication Using a Limited Capability Client Over a Low-Speed Communications Link, issued September 3, 2002.
The Invention Explained
- Problem Addressed: The patent describes the technical challenge of providing dynamic, interactive content to "limited capability" client devices, such as early Personal Digital Assistants (PDAs), which suffered from limited memory, little to no secondary storage, and slow, often wireless, network connections (’111 Patent, col. 1:47-2:10). It notes that traditional web "plug-ins" were a poor solution as they consumed valuable and permanent storage space on the client device even if used only once (’111 Patent, col. 5:45-54).
- The Patented Solution: In response to a client request, the server "dynamically" generates a "transient applet" that bundles both the specific data items requested by the user and the executable code (the "data interface capability") required to manipulate and display that data (’111 Patent, col. 2:56-3:10; Fig. 2). This self-contained applet is sent to the client, executed, and then "substantially discarded" after the session, thereby minimizing the impact on the client's limited storage resources (’111 Patent, col. 11:45-48).
- Technical Importance: This architecture was designed to reduce bandwidth consumption and client-side storage requirements, aiming to make data-rich, interactive applications more feasible on the resource-constrained mobile devices of its time (’111 Patent, col. 2:27-32).
Key Claims at a Glance
- The complaint alleges infringement of "one or more claims" without specifying which ones (Compl. ¶34). Independent claim 1 is representative of the asserted system.
- Independent Claim 1 recites a data processing system comprising:
- A server coupled to a communications link, operable to receive a request from a client and collect a plurality of data items in response.
- An "executable applet dynamically generated by the server" which includes a subset of the data items as "pre-loaded" values.
- A "data interface capability" associated with the applet, configured to provide operations on the pre-loaded values.
- The applet is operable to be transferred over the communications link to the client.
- The complaint does not explicitly reserve the right to assert dependent claims, but the broad allegation of infringing "one or more claims" leaves this possibility open.
III. The Accused Instrumentality
- Product Identification: The accused instrumentalities are the commercial websites operated by the numerous defendants, such as "www.abercrombie.com", "www.amazon.com", and "www.dell.com" (Compl. ¶¶ 35, 39, 51).
- Functionality and Market Context: The complaint alleges that the defendants' websites are operated via servers that receive requests from client devices (e.g., a user's web browser) (Compl. ¶35). These servers are alleged to infringe by collecting data items in response to requests and then creating and transmitting "executable applets" to the client device for operation (Compl. ¶35). The complaint does not provide technical specifics about the underlying technologies (e.g., JavaScript, AJAX) that allegedly constitute the "applets" but focuses on the functional outcome of providing dynamic website content.
IV. Analysis of Infringement Allegations
The complaint's infringement allegations are substantively identical for each defendant and largely track the language of the patent claims. The following chart summarizes the allegations for claim 1, using Abercrombie & Fitch Co. as a representative defendant.

No probative visual evidence provided in complaint.
- Identified Points of Contention:
- Scope Questions: A primary question will be whether the term "executable applet", as described in the patent in the context of Java and ActiveX technologies circa 1999, can be construed to read on the client-side scripting technologies (e.g., JavaScript, DHTML, AJAX) used by modern websites in 2010.
- Technical Questions: What evidence does the complaint provide that the accused websites perform "dynamic generation" of an "applet" in the specific manner claimed by the patent, versus a standard server-side process (e.g., PHP, ASP.NET) generating an HTML document that includes calls to pre-written, non-customized JavaScript libraries?
V. Key Claim Terms for Construction
The Term: "executable applet"
Context and Importance: The definition of this term is critical. If construed narrowly to mean only technologies like compiled Java applets that run in a Java Virtual Machine, the infringement case against modern websites using interpreted JavaScript may be significantly weakened. Practitioners may focus on this term because the patent's description appears rooted in the "plug-in" problem of the late 1990s, which is technologically distinct from how modern client-side scripts operate.
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The term "applet" is not explicitly defined or limited to a specific language in the claims. The specification states the applet may be a "Java, ActiveX or other suitable type of applet" and may be encoded in any "suitable programming language, scripting language, or the like," which may support a broader construction to include modern scripts (’111 Patent, col. 8:35-39).
- Evidence for a Narrower Interpretation: The specification repeatedly discusses Java applets, the Java Virtual Machine (JavaVM), and contrasts the invention with the problem of installing permanent "plug-ins" (’111 Patent, col. 6:28-50). This context may suggest that an "applet" is a specific type of self-contained, machine-independent program, not simply any client-side script embedded within a web page.
The Term: "dynamically generated by the server"
Context and Importance: This term is central to distinguishing the invention from merely serving a static file containing code. The nature of the "generation" will determine if the accused websites practice the invention.
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The term could be argued to cover any server-side process that assembles a response containing both data and code for a client.
- Evidence for a Narrower Interpretation: The patent describes a specific process where the "data manipulation system" (the code) is customized as a function of the "data items" (the payload) being sent in that specific response (’111 Patent, col. 11:55-62). This suggests a more bespoke creation process than a server simply populating a template with data and linking to a generic, pre-existing script library.
VI. Other Allegations
- Indirect Infringement: The complaint alleges that by operating their websites, Defendants induce their customers (the "others") to directly infringe, and contribute to that infringement (Compl. ¶36). The allegations assert that Defendants have the requisite knowledge and intent for such infringement (Compl. ¶37).
- Willful Infringement: For most defendants, willfulness is alleged based on knowledge acquired "at least since becoming aware of the '111 patent," suggesting a basis in post-filing conduct (Compl. ¶36). However, for Amazon.com and Kayak, the complaint alleges more directly that their "infringement is clear and...would necessarily be an objectively reckless act," suggesting a basis for pre-suit willfulness (Compl. ¶129).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of technological translation and scope: Can the term "executable applet", conceived in the late-1990s context of solving the "plug-in" problem for devices like PDAs using technologies such as Java, be construed to encompass the fundamentally different architecture of modern websites that use interpreted JavaScript within a browser?
- A key evidentiary question will be one of functional distinction: Does the operation of the accused websites—where a server typically generates an HTML document that references client-side scripts—constitute the specific, integrated act of "dynamically generating" a transient application that bundles customized code with its data payload, as claimed in the patent, or is it merely a conventional and distinct method of delivering web content?
