II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 10,687,708 - Method and Apparatus For A Compact And High Resolution Mind-View Communicator, Issued June 23, 2020
The Invention Explained
- Problem Addressed: The patent addresses the technical limitations of digital cameras in small form factors, which typically use smaller lenses and detector chips, resulting in lower image resolution compared to larger, more professional cameras (Compl. ¶33).
- The Patented Solution: The invention proposes a multi-camera system to overcome these limitations. It uses one camera with a wide field of view (FOV) and lower resolution to capture a broad scene, and a second camera with a narrower FOV and higher resolution to capture a more detailed view of an object within that scene (Compl. ¶36). The system then calculates the object's distance from the cameras and generates a composite output image where the object is sharp and the background is blurred, mimicking the way human eyes perceive depth (’708 Patent, Abstract; col. 15:10-21).
- Technical Importance: This approach allows compact devices like smartphones to computationally generate depth-of-field effects that were previously the domain of cameras with large lenses and apertures, creating a more professional and aesthetically pleasing image (Compl. ¶35, ¶37).
Key Claims at a Glance
- The complaint asserts independent claims 1 and 8 (Compl. ¶49).
- Independent Claim 1 recites an imaging method comprising the key steps of:
- Capturing a first image with a first camera having a first image resolution and first field of view.
- Capturing a second image with a second camera having a second image resolution that is higher than the first and a second field of view that is smaller than the first.
- Calculating the distance of an object in the scene from the multi-camera device.
- Generating an output image with an inner region and an outer region.
- The inner region's image resolution is higher than the first image's resolution, and the outer region's image resolution is lower than the first image's resolution.
- Saving the output image.
- The complaint reserves the right to assert dependent claims 3, 7, 9, 11, 13, 14, 16, 17, 18, and 19 (Compl. ¶49).
U.S. Patent No. 10,623,705 - Method and Apparatus for a Wearable Imaging Device, Issued April 14, 2020
The Invention Explained
- Problem Addressed: The patent addresses the challenge of creating high-quality, human-like images with depth effects using compact, wearable devices that are physically constrained by small components ('705 Patent, col. 1:30-50).
- The Patented Solution: The invention describes a portable apparatus with two camera modules. A first, lower-resolution module captures a wide "main scene," while a second, higher-resolution module captures a "second scene" that is a subset of the first ('705 Patent, col. 17:15-28). A processor estimates an object's distance, executes an "image blurring procedure" based on that distance to reduce the resolution of parts of the image, and generates a final output with a focused subject against a blurred background ('705 Patent, col. 17:48-59).
- Technical Importance: The technology provides a specific method for achieving computational "Bokeh" effects in small devices by combining information from two distinct camera systems to create a final image with variable focus and resolution ('705 Patent, col. 10:55-65).
Key Claims at a Glance
- The complaint asserts independent claim 1 (Compl. ¶61).
- Independent Claim 1 recites a portable imaging apparatus comprising:
- A first camera module with a first field of view and first image resolution.
- A second camera module with a second image resolution that is higher than the first, capturing a second scene that is a subset of the first scene.
- A processor configured to execute a distance calculation procedure, an image blurring procedure, and generate an output image with two areas.
- The second area (background) is blurred, and its resolution is less than the resolution of the first area (subject).
- The complaint reserves the right to assert dependent claims 3, 5, and 9 (Compl. ¶61).
III. The Accused Instrumentality
Product Identification
- A wide range of Samsung Galaxy smartphones and tablets that include "Portrait or Live Focus modes" (collectively, the "Accused Products") (Compl. ¶45, ¶49, ¶61).
Functionality and Market Context
- The complaint alleges that the Accused Products contain multiple built-in cameras with different lenses and resolutions, such as wide-angle, ultra-wide, and telephoto lenses (Compl. ¶46).
- The infringement allegation centers on the "Portrait mode" feature. This mode is alleged to use at least two captured images to computationally "calculate distances to objects" and then "emphasize the object by blurring the area around the object," a process that creates the "Bokeh" effect (Compl. ¶47).
- The complaint alleges that Samsung markets these devices for their ability to generate high-resolution photographs with these specific visual effects and sells them through its website and major third-party retailers (Compl. ¶45, ¶46).
- No probative visual evidence provided in complaint.

Identified Points of Contention
- Scope Questions: The patents describe a system with a "lower resolution" camera and a "higher resolution" camera. A question for the court will be whether Samsung's implementation, which may use two very high-resolution cameras where one is simply of a different resolution than the other, meets the specific relational requirements of the claims. For example, in the '708 patent, does the final blurred "outer region" have a resolution that is demonstrably "lower than the image resolution of the first image," or is it merely a filtered version of an originally high-resolution capture?
- Technical Questions: A key factual question will be how Samsung's "Portrait mode" software functions. The patents describe calculating distance via "triangulation" ('708 Patent, col. 19:12-16). What evidence does the complaint provide that the accused software uses this specific method, as opposed to other modern techniques like AI-driven depth mapping or semantic segmentation? The definition of "distance calculation procedure" will be critical.
V. Key Claim Terms for Construction
The Term: "image resolution"
Context and Importance
This term is foundational to the infringement analysis for both patents, as the claims rely on specific comparisons ("higher than," "lower than") between the resolutions of different cameras and different regions of the final output image. The viability of the infringement case depends on how resolution is measured for the original and processed images.
Intrinsic Evidence for Interpretation
- Evidence for a Broader Interpretation: A party could argue for the plain and ordinary meaning, such as the total pixel count of a sensor (e.g., 48 megapixels vs. 12 megapixels). The specification's frequent reference to cameras having different pixel counts may support this view (Compl. ¶33).
- Evidence for a Narrower Interpretation: A party could argue the term is a more nuanced concept than just sensor size, pointing to the '705 patent's disclosure of an "image blurring procedure, to reduce the image resolution" ('705 Patent, col. 17:48-51). This suggests "resolution" can refer to the effective resolution after computational processing, not just the native hardware specification.
The Term: "calculating... the distance" (’708 Patent, Claim 1) / "distance calculation procedure" (’705 Patent, Claim 1)
Context and Importance
The core of the patented invention involves using distance information to generate the blur effect. The definition of this term will determine whether Samsung’s proprietary method for creating the "Bokeh" effect falls within the claims.
Intrinsic Evidence for Interpretation
- Evidence for a Broader Interpretation: Plaintiff may argue the term should encompass any computational method that determines an object's distance from the camera to inform the blurring algorithm, regardless of the specific technique used.
- Evidence for a Narrower Interpretation: Defendant may argue the term is limited by the patents' own disclosures. Both patents repeatedly teach that distance is estimated via "triangulation" applied to the images from the different cameras (’708 Patent, col. 19:12-16; '705 Patent, col. 6:35-37). Practitioners may focus on this term because this explicit disclosure could be used to argue that the claim scope is limited to this specific method, potentially excluding infringement by devices that use other depth-sensing technologies like AI-based scene analysis.
VI. Other Allegations
Indirect Infringement
- The complaint alleges that Samsung induces infringement by selling the Accused Products and providing materials such as user guides, technical support, and advertising that instruct and encourage customers to use the accused "Portrait" and "Live Focus" modes in their intended, infringing manner (Compl. ¶54, ¶66).
Willful Infringement
- The willfulness allegation is based on Samsung's knowledge of the Asserted Patents, which the complaint alleges began "at least upon the service of this Complaint" (Compl. ¶53, ¶65). The complaint asserts that any continued infringement by Samsung after receiving notice of the lawsuit is intentional, deliberate, and willful (Compl. ¶59, ¶70).
VII. Analyst’s Conclusion: Key Questions for the Case
- A key evidentiary question will be one of technical mechanism: do the accused "Portrait" and "Live Focus" modes operate by "calculating distance" using the multi-camera triangulation method described in the patents, or do they rely on fundamentally different technologies, such as AI-based depth mapping, that may fall outside the scope of the claims?
- A central issue will be one of claim scope and measurement: how is "image resolution" to be construed and measured for the various camera sensors and the computationally generated regions of the final photograph? The case may turn on whether Samsung's products can be shown to meet the specific "higher than" and "lower than" relational limitations required by the asserted claims.
- A third issue will be one of definitional scope: can the patents, which originated in the context of wearable "eye-view" recorders, be broadly applied to the multi-camera array and software architecture of a modern mass-market smartphone, or are there fundamental mismatches in the recited structures and functions?
