II. Technology and Patent(s)-in-Suit Analysis
- Patent Identification: U.S. Patent No. 8,078,498, “Virtual Showroom System and Method,” issued December 13, 2011.
The Invention Explained
- Problem Addressed: The patent and complaint describe the technical challenges of online retail in the early 2000s, particularly the difficulty for consumers to "adequately evaluate" tangible products through a two-dimensional web interface and the slow performance of websites that displayed multiple large images over then-prevalent dial-up internet connections ('498 Patent, col. 1:29-34; Compl. ¶¶16, 18).
- The Patented Solution: The invention proposes a method where a product is displayed with one large image in a "master display field" and a plurality of smaller "thumbnail images." These thumbnails each represent a different perspective view (e.g., front, rear, side) of the same product. A user can select a thumbnail, which causes the corresponding view to be displayed in the master field. This method is intended to preserve bandwidth by loading only the selected large image on demand, while providing the user with comprehensive visual information ('498 Patent, Abstract; col. 4:16-34). The selected thumbnail is also given a "distinctive characteristic" to visually distinguish it from the others ('498 Patent, col. 4:56-65).
- Technical Importance: The complaint alleges this approach improves webpage performance and provides a more intuitive user interface compared to prior systems that either showed fewer images or forced the loading of a full gallery of large images, which was inefficient ('498 Patent, col. 2:12-15; Compl. ¶¶17, 23).
Key Claims at a Glance
- The complaint asserts independent claims 1, 7, and 11, and dependent claims 2, 5, 6, and 8 (Compl. ¶26).
- Independent Claim 1 recites a method of displaying an article, with the essential elements including:
- Providing a plurality of thumbnail images of an article, where each thumbnail is an icon representing a different perspective view (from the group of front, rear, side, and isometric).
- Allowing a user to select one of the thumbnails for display in a "master display field."
- Providing a "distinctive characteristic" to the selected thumbnail.
- Displaying the "selected one of said plurality of thumbnail images" in the master display field.
- Independent Claim 7 is similar to claim 1 but is directed to a method for displaying a plurality of different articles, rather than multiple views of a single article.
- Independent Claim 11 is directed to a method involving providing a first and a second thumbnail image representing different perspective views of the same article and allowing a user to select one for display.
- The complaint reserves the right to assert additional dependent claims (Compl. ¶26).
III. The Accused Instrumentality
Product Identification
- The accused instrumentalities are Defendant's websites, www.nordstrom.com and www.nordstromrack.com (the "Websites") (Compl. ¶4).
Functionality and Market Context
- The complaint alleges that the Websites utilize a "virtual showroom" method for displaying products to consumers (Compl. ¶27). The accused functionality involves providing a main product image and several selectable thumbnail images that show the product from different angles. When a user selects a thumbnail, the main image display is updated to show that view (Compl. ¶¶28-30). The complaint positions the parties as direct competitors in the apparel retail market (Compl. ¶6). No probative visual evidence provided in complaint.
IV. Analysis of Infringement Allegations
The complaint references claim charts in an attached Exhibit C, which was not available for this analysis (Compl. ¶33). The following summary is based on the narrative allegations in the complaint body.
'498 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| providing, by a processor, a plurality of thumbnail images of said article, each image comprising an icon and representing a respective perspective view of said article, allowing a user...to select one of said plurality of thumbnail images for display in a master display field...each respective perspective view being selected from the group consisting of front, rear, side, and isometric views | Through the Websites, Defendant allegedly provides, via a processor, several thumbnail images of articles that each represent a different perspective view (from the group of front, rear, side, and isometric views), which a user can select for display in a master display field. | ¶28 | col. 4:16-34 |
| providing a distinctive characteristic to said one of said plurality of thumbnail images selected by said user | The Websites allegedly provide a distinctive characteristic to the thumbnail image that a user selects. | ¶29 | col. 4:56-65 |
| displaying said selected one of said plurality of thumbnail images in said master display field | The Websites allegedly display the thumbnail image selected by the user in the master display field. | ¶30 | col. 4:29-32 |
- Identified Points of Contention:
- Scope Questions: Claim 1 recites displaying "said selected one of said plurality of thumbnail images in said master display field." A primary dispute may arise over whether this requires displaying the small thumbnail image itself in the main viewing area, or if it can be read to cover the common e-commerce practice of displaying a corresponding larger image. The complaint alleges infringement under the doctrine of equivalents as an alternative, suggesting this may be a known point of contention (Compl. ¶31).
- Technical Questions: A factual question for the court will be whether the accused Websites provide perspective views from the specific Markush group recited in claim 1 ("front, rear, side, and isometric views"). Evidence regarding the specific views offered for products on the Websites will be necessary to resolve this element.
V. Key Claim Terms for Construction
The Term: "displaying said selected one of said plurality of thumbnail images in said master display field"
- Context and Importance: The construction of this phrase appears central to the literal infringement analysis. If construed narrowly to mean only the thumbnail itself is displayed in the master field, it could present a significant hurdle for the plaintiff’s literal infringement theory, as most modern websites display a larger, higher-resolution image.
- Intrinsic Evidence for a Broader Interpretation: The patent specification repeatedly describes the master display field as showing a "larger electronic image" of the selected item to allow the user to "more thoroughly evaluate the featured undergarment" ('498 Patent, col. 4:30-40). This purpose-driven language may support a construction where "displaying said...thumbnail" is understood to mean displaying the image represented by the thumbnail.
- Intrinsic Evidence for a Narrower Interpretation: A defendant may argue that the claim language is plain and unambiguous. The patentee chose to recite "displaying said selected...thumbnail image" and not, for example, "displaying a larger image corresponding to the selected thumbnail image," and should be held to that specific language.
The Term: "distinctive characteristic"
- Context and Importance: The definition of this term will determine what forms of user interface feedback meet the claim limitation. Practitioners may focus on this term because its scope will be a factual question applied to the specific highlighting method (e.g., underlining, color change, border) used on the accused Websites.
- Intrinsic Evidence for a Broader Interpretation: The specification provides examples such as a different "color scheme" or a "size larger than" the other thumbnails, suggesting the term is not limited to a single method of distinction ('498 Patent, col. 4:62-65; col. 5:6-10).
- Intrinsic Evidence for a Narrower Interpretation: While the specification gives examples, a defendant could argue that the characteristic must be a significant visual alteration on par with those examples, and that a more subtle form of highlighting (e.g., a thin border) does not qualify as "distinctive."
VI. Other Allegations
- Indirect Infringement: The complaint alleges induced infringement, stating that Nordstrom instructs and encourages users to infringe by providing the Websites and related marketing materials (e.g., catalogs, email alerts) that direct users to perform the claimed methods (Compl. ¶¶34, 36).
- Willful Infringement: Willfulness is alleged based on knowledge of the '498 Patent "since at least the filing of this Complaint" (Compl. ¶36). This allegation forms a basis for seeking enhanced damages for any post-filing infringement. No facts supporting pre-suit knowledge are alleged.
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of definitional scope: can the claim limitation "displaying said selected one of said plurality of thumbnail images" be construed to read on a system that displays a corresponding larger image? The outcome of this claim construction, or the subsequent analysis under the doctrine of equivalents, will likely be determinative for infringement.
- A key evidentiary question will be one of factual compliance: does the accused functionality of the Nordstrom websites meet the specific requirements of the claims, particularly the limitation that perspective views must be selected from the group of "front, rear, side, and isometric views"? This will require a detailed factual analysis of the accused websites' operation.
- A final question will concern intent for indirect infringement: what evidence can be produced to demonstrate that Nordstrom, by operating its websites and marketing them to customers, specifically intended for users to perform the patented method in a way that constitutes infringement?
