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

U.S. Patent No. 9,792,662 - Embedding Digital Content Within a Digital Photograph During Capture of the Digital Photograph, issued October 17, 2017

The Invention Explained

• Problem Addressed: The patent specification describes a shortcoming in prior art digital photography where enhancing a photograph, such as by adding a label or special effect, required a separate process to be performed after the photograph was taken (Compl. ¶18; ’873 Patent, col. 2:9-16).
• The Patented Solution: The invention provides a system where digital content (e.g., a watermark, icon, or text) is displayed as an overlay on the live camera view within the device’s screen prior to and during image capture. When the user takes the picture, the resulting digital file is a "What You See Is What You Get (WYSIWYG)" representation that merges the captured scene with the digital overlay, streamlining the process into a single step (’873 Patent, col. 2:28-45).
• Technical Importance: This approach integrates the act of contextualizing or customizing a digital image directly into the act of capturing it, rather than treating it as a subsequent, multi-step editing task (Compl. ¶18).

Key Claims at a Glance

• The complaint asserts independent claim 1 and dependent claims 6, 12, and 16 (Compl. ¶26).
• Independent Claim 1 requires, in essence:
  • Receiving a user's selection of an "embeddable content image."
  • Displaying the selected content image on the device's image viewing structure.
  • Displaying the real-time visual content from the camera in combination with the selected content image.
  • Maintaining the selected content image at a "static position" on the screen, independent of the camera's field of view.
  • Displaying the selected content image as a "mask applied to the visual content" being captured.
  • Outputting a data structure for the final visual image that includes the selected content image and the portions of the captured visual content visible through the mask.

U.S. Patent No. 10,102,601 - Embedding Digital Content Within a Digital Photograph During Capture of the Digital Photograph, issued October 16, 2018

The Invention Explained

• Problem Addressed: As with the related ’662 Patent, this patent addresses the problem of enhancing digital photographs through separate, post-capture editing processes (’601 Patent, col. 2:5-16).
• The Patented Solution: The invention solves this by displaying embeddable content over a live camera view, allowing a user to frame and capture a single WYSIWYG image that includes both the real-world scene and the digital overlay (’601 Patent, col. 2:28-45). This is achieved by displaying the embeddable content in a foreground layer and the live camera feed in a background layer, which are then merged upon capture (’601 Patent, col. 7:31-38).
• Technical Importance: The technology allows for the creation of customized and contextualized images at the moment of capture, an approach that has become foundational to many social media applications (Compl. ¶18).

Key Claims at a Glance

• The complaint asserts claims 2-11, 14, and 16; claims 2 and 9 are independent (Compl. ¶39).
• Independent Claim 9 requires, in essence:
  • Displaying a combined visual image in the device's viewing structure, which includes a "captured image" from the device in real time and an "embeddable content image."
  • The embeddable content image is displayed as a "mask" over the captured image.
  • The embeddable content image is maintained in a "static position" in the viewing structure during the taking of the photograph.
  • Generating a digital file of the combined visual image, which includes the embeddable content and the captured image as it was displayed during capture.

U.S. Patent No. 10,489,873 - Embedding Digital Content Within a Digital Photograph During Capture of the Digital Photograph, issued November 26, 2019

• Patent Identification: U.S. Patent No. 10,489,873, “Embedding Digital Content Within a Digital Photograph During Capture of the Digital Photograph,” issued November 26, 2019 (Compl. ¶13).
• Technology Synopsis: This patent, which shares a common specification with the other patents-in-suit, discloses a method for overcoming the limitations of post-capture photo editing. The invention enables a user to select digital content (e.g., an icon or text) and have it displayed over a live camera view, maintained in a static position as a mask, so the user can frame and capture a final WYSIWYG image that merges the live view and the digital overlay (Compl. ¶¶ 18-19).
• Asserted Claims: Independent claim 1 and dependent claims 2-3, 7, 9-14, 17-20, and 23 are asserted (Compl. ¶52).
• Accused Features: The complaint alleges that the "effects" features of the TikTok app infringe this patent (Compl. ¶52).

III. The Accused Instrumentality

• Product Identification: The accused instrumentality is the "TikTok app," a mobile application for creating and sharing short videos, with specific focus on its "effects" features (Compl. ¶¶ 3, 26, 39, 52).
• Functionality and Market Context: The complaint describes the TikTok app as a video-sharing social network that allows users to create short videos, often with music, and edit them with filters or speed adjustments (Compl. ¶4). The accused "effects" features are alleged to perform the patented method of overlaying content during capture (Compl. ¶¶ 32, 45, 58). The complaint alleges the app's significant market presence, with over one billion users worldwide as of August 2020 (Compl. ¶3). No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

The complaint references claim chart exhibits detailing the infringement allegations for each patent-in-suit (Exs. 8, 9, and 10), but these exhibits were not included with the filed complaint document (Compl. ¶¶ 27, 40, 53). In their absence, the infringement theory is based on the narrative allegations.

The core of Plaintiff's infringement theory is that the "effects" features in the TikTok app practice the claimed inventions. The complaint alleges that when a user selects an "effect" (such as a filter, sticker, or other digital content), the TikTok app overlays that content on the live camera view shown on the user's screen. This overlay is allegedly maintained in a static position and acts as a mask on the live video feed. When the user captures a video, the final output file allegedly combines the captured scene with the overlaid effect, mirroring the WYSIWYG process described in the patents (Compl. ¶¶ 18-19, 26, 39, 52).

• Identified Points of Contention:
  • Scope Questions: A central issue may be whether the term "photograph" and the act of "taking a photograph," as recited throughout the patents (e.g., ’601 Patent, Claim 9), can be construed to read on the capture of a video, which is the primary function of the accused TikTok app. The court may need to decide if capturing a sequence of frames is equivalent to taking a photograph for the purposes of the claims.
  • Technical Questions: The claims require maintaining an "embeddable content image" at a "static position" (e.g., ’662 Patent, Claim 1). This raises the question of whether this limitation is met by all of TikTok’s accused "effects." While some effects may be static overlays (e.g., a fixed frame or logo), many are dynamic AR effects that track and move with faces or objects in the scene, which may present a mismatch with the "static position" requirement.

V. Key Claim Terms for Construction

Term 1: "photograph"

• Context and Importance: This term is critical because the patents consistently refer to capturing a "photograph," while the accused product is primarily a video creation and sharing application. The construction of this term could determine whether the patents apply to video capture at all.
• Intrinsic Evidence for a Broader Interpretation: A party could argue that the specification's focus on "digital photography" in a general sense should encompass the capture of any digital image data, including the individual frames that constitute a video (’601 Patent, col. 1:55-56).
• Intrinsic Evidence for a Narrower Interpretation: A party could argue that the repeated use of the singular "photograph" and "photo," along with embodiments showing the capture of a single still image, limits the term to its conventional meaning of a single static picture (’601 Patent, Figs. 2A-2H; col. 2:9-11).

Term 2: "maintaining... at a static position"

• Context and Importance: This term defines a key functional aspect of the invention. Its construction will be central to determining whether dynamic, object-tracking, or interactive AR "effects" in the TikTok app fall within the scope of the claims.
• Intrinsic Evidence for a Broader Interpretation: The specification states the content is maintained at a static position "within an area of the image viewing structure" (’601 Patent, col. 4:13-15). This could be interpreted to mean static relative to the screen, covering any fixed overlay regardless of camera movement.
• Intrinsic Evidence for a Narrower Interpretation: The specification contrasts the invention with post-capture editing, focusing on framing a scene with a fixed overlay like a watermark or text (’601 Patent, col. 4:40-49). This context may support a narrower construction that excludes effects that dynamically interact with or move in response to content within the live camera view.

VI. Other Allegations

• Indirect Infringement: The complaint alleges inducement, asserting that TikTok specifically intended for its customers to infringe by providing instructions and encouragement for using the accused "effects" features. This intent is allegedly evidenced by TikTok's product support webpage (Compl. ¶¶ 32, 45, 58).
• Willful Infringement: The complaint alleges that TikTok has knowledge of the patents-in-suit and their infringement "based, at least, on its receipt of this Complaint" (Compl. ¶¶ 30, 43, 56). This allegation supports a claim for post-suit willful infringement. The prayer for relief also requests a finding that the case is "exceptional" under 35 U.S.C. § 285 (Compl. p. 14, ¶(vi)).

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

• A core issue will be one of definitional scope: can the term "photograph," rooted in the patent's context of capturing a single still image, be construed to cover the act of recording video frames, the primary function of the accused TikTok application?
• A key evidentiary question will be one of technical correspondence: do the varied and often dynamic "effects" in the TikTok app perform the same function as the claimed "embeddable content image" that is maintained in a "static position," or is there a fundamental mismatch between the accused AR technology and the simpler overlay system described in the patent specification?
• The viability of the indirect infringement claim will likely depend on a question of specific intent: does evidence of TikTok providing general instructions for its "effects" features prove that it specifically intended users to perform every limitation of the patented methods, particularly if there are arguable differences in scope and technical operation?
