II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 7,590,636 - Knowledge Filter
- Issued: September 15, 2009
The Invention Explained
- Problem Addressed: The patent identifies shortcomings in prior art network-based knowledge sharing systems like "threaded discussion" forums. These prior systems offered no way to determine the usefulness of a contribution, lacked a logical structure for organization, and became unwieldy and difficult to search as the volume of posts increased (’636 Patent, col. 1:37-51).
- The Patented Solution: The invention is described as a "self-organizing knowledge base" that allows a group of users to build a repository of information and then use ratings and comments to rank and sort that information (’636 Patent, col. 1:15-22). The system collects submissions from users and organizes them within a "hierarchically organized category structure," using an embodiment described as a "Cookbook" for recipes as a primary example (’636 Patent, col. 7:12-23). Users can then sort the information based on various criteria derived from the collective ratings, allowing them to find the most valuable content.
- Technical Importance: The patent asserts that this approach improves upon prior systems by providing a framework that "automatically presents the information that is most meaningful or useful to an individual user" without discarding other information in the database (’636 Patent, col. 3:6-9).
Key Claims at a Glance
- The complaint asserts dependent claims 4, 5, 8, and 9, which all depend from independent method claim 1. (Compl. ¶ 29).
- The essential elements of independent claim 1 are:
- A computer system storing items of information in a database, where the items are received from a first set of remote computer systems.
- The computer system receiving submissions (including a rating and/or comment) about the stored items from a second set of remote computer systems.
- The computer system storing the received submissions.
- The computer system receiving a request from a remote computer to view a listing of the stored items ordered according to a "selected criterion that pertains to the stored submissions."
- The computer system providing data to the remote computer to display the ordered listing.
- The complaint reserves the right to amend its infringement contentions. (Compl. ¶ 31).
III. The Accused Instrumentality
Product Identification
The "Accused Instrumentalities" are identified as Defendant's website and/or the computer systems that host the website, with a specific product page for "shea soap" provided as an example (Shea Soap Product Page) (Compl. ¶ 29).
Functionality and Market Context
The complaint alleges that the accused website performs a method wherein "user comments and ratings were collected and stored" for products sold by The Body Shop (Compl. ¶ 29). This system is further alleged to allow users to "access and sort such items of information according to selected rating criteria in order to find the most reliable and/or valuable information" (Compl. ¶ 30). The complaint asserts that Defendant used this patented method to "drive sales of its cosmetics, body care and other products" (Compl. ¶ 15).
IV. Analysis of Infringement Allegations
The complaint states that an exemplary infringement analysis is provided in an "Exhibit B" (Compl. ¶ 31); however, that exhibit was not attached to the complaint document. The following chart is constructed based on the narrative infringement allegations within the complaint.
No probative visual evidence provided in complaint.
’636 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| a computer system storing items of information in a database, wherein the items are received from a first set of two or more of a plurality of remote computer systems | The Body Shop's computer systems store information regarding products, such as cosmetics and body care, for sale on its website. | ¶29 | col. 13:30-34 |
| the computer system receiving, via the computer network, submissions regarding two or more particular ones of the stored items of information, wherein each submission is received from a corresponding one of a second set of two or more of the plurality of remote computer systems, wherein each of said submissions includes a rating and/or a comment | The Body Shop's website solicits and receives ratings and comments from users regarding its products. | ¶29 | col. 13:35-43 |
| the computer system storing the received submissions in the database | The collected user ratings and comments are stored in a database associated with the website. | ¶29 | col. 13:44-45 |
| the computer system receiving a request from a given one of the plurality of remote computer systems to view a listing of the stored items of information according to an ordering consistent with a selected criterion that pertains to the stored submissions | The website allows users to access and sort items of information according to selected rating criteria. | ¶30 | col. 13:46-52 |
| responsive to the request, the computer system providing a first set of data to the given remote computer system... to display said listing of the stored items according to said ordering | The website displays a sorted list of products to the user based on the selected rating criteria. | ¶30 | col. 13:53-58 |
Identified Points of Contention
- Scope Questions: A primary question may be whether the term "items of information", which is exemplified in the patent as user-contributed "recipes" in a "Cookbook" embodiment ('636 Patent, col. 7:19-23), can be construed to read on commercially-offered products listed on an e-commerce website, as alleged in the complaint (Compl. ¶ 29).
- Technical Questions: A key factual question will be whether The Body Shop's website performs the specific functions required by the asserted dependent claims. For example, does the accused system "prevent a given contribution source from rating a given one of the stored items of information more than once," as required by asserted claim 9? The complaint does not provide specific evidence on this operational detail.
V. Key Claim Terms for Construction
The Term: "items of information" (Claim 1)
Context and Importance: The definition of this term is central to the scope of the patent. The infringement theory depends on construing commercially-listed products as "items of information." Practitioners may focus on this term to determine if the patent, which describes a collaborative "knowledge base," applies to a conventional e-commerce catalog.
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The term itself is general and not explicitly defined or limited in the claims. The "Summary of the Invention" describes a general "method and system for sharing knowledge" by receiving "information input into a database" ('636 Patent, col. 3:43-46).
- Evidence for a Narrower Interpretation: The specification's main embodiment is a "Cookbook," where it is stated that "for the CookBook an Item is a recipe" ('636 Patent, col. 7:22-23). This could support an argument that "items" are limited to user-generated, informational content rather than products for sale.
The Term: "extensible hierarchy of information categories" (Asserted Claim 4)
Context and Importance: Infringement of asserted claim 4 requires the presence of this feature. The dispute may turn on whether a standard, pre-defined e-commerce navigation menu (e.g., Body > Soaps > Shea Soap) qualifies as an "extensible hierarchy."
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The patent depicts hierarchical category maps that resemble website navigation structures ('636 Patent, FIG. 6). The term "hierarchy" itself can describe such a structure.
- Evidence for a Narrower Interpretation: The patent describes "allowing users to add new subject or topic divisions to the knowledge base" ('636 Patent, col. 5:42-43) and includes a "Create New Category" interface function ('636 Patent, FIG. 4, item 410). This may support a narrower construction where "extensible" requires the ability for users to create new categories, not just for an administrator to modify a fixed commercial structure.
VI. Other Allegations
- Indirect Infringement: The complaint does not include a separate count for indirect infringement. It does, however, allege in its direct infringement count that Defendant "caused to be used by others" the infringing systems (Compl. ¶ 29).
- Willful Infringement: The complaint does not explicitly allege willful infringement or plead facts suggesting Defendant had pre-suit knowledge of the ’636 patent. However, in its prayer for relief, Plaintiff seeks a "declaration that this case is exceptional under 35 U.S.C. § 285" and an award of attorneys' fees (Compl., Prayer for Relief ¶ C).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of definitional scope: Can the claims, which describe a system for filtering a collaboratively-built "knowledge base" of user-contributed "items" like recipes, be construed to cover the standard product rating and sorting features of a modern e-commerce platform where the items are commercial goods?
- A second central issue, preemptively addressed by the Plaintiff (Compl. ¶¶ 19-23), will be patent eligibility under 35 U.S.C. § 101. The court will need to determine whether the claims are directed to a patent-ineligible abstract idea (such as organizing information based on user feedback) or to a specific, non-conventional improvement in computer functionality.
- A key evidentiary question will be one of technical implementation: Does the accused website actually perform all the specific steps recited in the asserted dependent claims, such as preventing a single user from rating the same product more than once (Claim 9), a technical detail not substantiated in the complaint.
