Case Timeline

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

U.S. Patent No. 9,529,918 - System and methods thereof for downloading applications via a communication network, issued December 27, 2016

The Invention Explained

• Problem Addressed: The patent identifies a problem with conventional application repositories (e.g., app stores) where searching for a desired application is often "very time consuming" and requires navigating "through tens or hundreds of applications." It notes that search results are often promoted by the repository owner and may not align with the user's actual "needs or intent." (’918 Patent, col. 2:4-12).
• The Patented Solution: The invention proposes a system that goes beyond simple keyword matching. It receives a user's search query and determines the "search intent," which represents the user's specific topic of interest. This determination can be "explicit," based on analyzing the query itself, or "implicit," based on environmental variables like location and time of day (’918 Patent, col. 4:7-12). Based on this determined intent, the system selects a relevant application, displays its icon in a "display segment" on the user's device, and, upon user selection, establishes a "direct communication link" to download the application from its source (’918 Patent, Abstract; col. 4:54-68).
• Technical Importance: The technology aims to improve the user experience of application discovery by providing more contextually aware and relevant search results, thereby reducing the time and effort required to find a suitable application (’918 Patent, col. 2:9-12).

Key Claims at a Glance

• The complaint asserts "Exemplary '918 Patent Claims" identified in an external exhibit (Compl. ¶11). Based on the patent’s structure, independent claim 1 is a representative method claim.
• Independent Claim 1 (Method) requires:
  • receiving, via a communication network, an input search query from a user device;
  • determining the search intent based on the input search query;
  • selecting, based on the search intent, at least one application from at least one applications central repository;
  • causing an icon corresponding to the at least one selected application to be displayed on a display of the user device;
  • receiving an input from the user device indicating a particular one of the at least one selected application;
  • causing establishment of a direct communication link between the user device and a location hosting the particular application; and
  • causing initiation of a download of the particular application to the user device over the direct link.
• The complaint does not specify whether dependent claims are also asserted at this stage.

III. The Accused Instrumentality

Product Identification

The complaint identifies the accused instrumentalities as the "Exemplary Defendant Products," which are detailed in charts incorporated as Exhibit 2 (Compl. ¶11, ¶16). The complaint body itself does not name specific ASUSTOR products.

Functionality and Market Context

The complaint alleges that the accused products "practice the technology claimed by the '918 Patent" (Compl. ¶16). This suggests the products are systems or services that allow users to search for, select, and download software applications. The infringement allegations imply these products perform functions corresponding to determining user search intent and facilitating application downloads in a manner that allegedly satisfies all elements of the asserted claims (Compl. ¶16). The complaint does not provide detail on the products' market context beyond alleging they are made, used, sold, and imported in the United States (Compl. ¶11, ¶14).

IV. Analysis of Infringement Allegations

The complaint references but does not include its claim chart exhibit (Exhibit 2), which it states compares the "Exemplary '918 Patent Claims to the Exemplary Defendant Products" (Compl. ¶16). The narrative alleges that these products "satisfy all elements of the Exemplary '918 Patent Claims" (Compl. ¶16). Lacking the specific charts, the infringement theory must be summarized from the complaint’s general allegations. The core allegation is that the accused products implement an application search-and-download system that mirrors the steps of the patent’s claims, including receiving a query, selecting an application, displaying it, and facilitating its download (Compl. ¶11, ¶16).

No probative visual evidence provided in complaint.

Identified Points of Contention

• Technical Questions: A central question will be how the accused products "determine the search intent." The patent describes a sophisticated process involving "explicit" and "implicit" intent analysis using various engines and tokenizers (’918 Patent, col. 4:7-35; col. 7:1-8:43). The case may turn on whether the accused products perform a comparable analysis or merely a conventional keyword search, and whether the latter falls within the scope of the claims.
• Scope Questions: The meaning of "direct communication link" may be a point of dispute. The infringement analysis will need to address whether the link established by the accused products is "direct" in the manner contemplated by the patent, which describes a link between the user device and the application's hosting location (’918 Patent, col. 5:48-51).

V. Key Claim Terms for Construction

The Term: "determining the search intent"

Context and Importance

This term is the central innovative concept of the patent. The outcome of the infringement analysis will heavily depend on whether this term is construed broadly to cover any form of query analysis or narrowly to require the specific multi-faceted process described in the patent.

Intrinsic Evidence for Interpretation

• Evidence for a Broader Interpretation: A party might argue that the plain language of the claim does not import the specific limitations from the specification, and that any process that determines a user's goal from a query meets the limitation.
• Evidence for a Narrower Interpretation: The specification provides a detailed description of how "search intent" is determined, including distinguishing between "implicit intent" (based on environmental variables) and "explicit intent" (based on tokenizing a query and processing it through multiple "engines") (’918 Patent, col. 4:7-35; col. 9:19-10:54). A party could argue these detailed descriptions define and limit the scope of the claimed term.

The Term: "direct communication link"

Context and Importance

This term defines the mechanism for downloading the application. Its construction will be important to determine if the accused system's architecture meets the claim. Practitioners may focus on this term to dispute whether an intermediated or brokered download process still qualifies as "direct."

Intrinsic Evidence for Interpretation

• Evidence for a Broader Interpretation: One could argue "direct" simply means the link facilitates the download without requiring the user to navigate away to a separate app store interface manually.
• Evidence for a Narrower Interpretation: The specification states the link is established "between a source of the at least one selected application and the user device" (’918 Patent, col. 5:48-51). This could be interpreted to require a point-to-point connection that bypasses other servers, potentially excluding architectures where a central server (like the defendant's) remains involved in managing the download stream.

VI. Other Allegations

Indirect Infringement

The complaint alleges induced infringement, stating that Defendant distributes "product literature and website materials" that instruct and encourage end users to use the accused products in a manner that directly infringes the ’918 Patent (Compl. ¶14-15).

Willful Infringement

The willfulness allegation is based on post-suit knowledge. The complaint asserts that the service of the complaint itself provides "actual knowledge" of infringement and that Defendant's continued infringing activities despite this knowledge are willful (Compl. ¶13-14).

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

• A core issue will be one of definitional scope: can the term "determining the search intent," which the patent describes as a complex analytical process, be construed to cover the specific method of query processing used by ASUSTOR’s accused products? The answer will depend on whether the court limits the claim term to the detailed embodiments in the specification.
• A key evidentiary question will be one of technical implementation: assuming a claim construction is established, what evidence will show that the accused products actually perform each claimed step? In particular, discovery will likely focus on the architecture of the download process to resolve whether it establishes a "direct communication link" as required by the claims.
