II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 8,531,555 - "Method and Apparatus for Automatically Categorizing Images in a Digital Camera"
- Patent Identification: U.S. Patent No. 8,531,555, "Method and Apparatus for Automatically Categorizing Images in a Digital Camera", issued September 10, 2013.
The Invention Explained
- Problem Addressed: The patent addresses the inefficiency of manually categorizing large numbers of digital images, which it describes as a "cumbersome and time-consuming task" for users of digital cameras and other imaging devices (’555 Patent, col. 1:39-44).
- The Patented Solution: The invention is a device, such as a digital camera, that automatically analyzes image data as it is being captured to generate one or more "tags" that describe the image's content ('555 Patent, Abstract). These tags are then stored with the image data, allowing for automated sorting and categorization without manual user intervention ('555 Patent, col. 2:11-17). The analysis is performed by dedicated software modules within the camera's processing pipeline ('555 Patent, col. 5:37-43).
- Technical Importance: This approach sought to improve the user experience by embedding organizational intelligence directly into the imaging device, making image management more efficient than post-capture sorting on a separate computer ('555 Patent, col. 2:1-6).
Key Claims at a Glance
- The complaint asserts independent claim 1 ('555 Patent, Compl. ¶20).
- The essential elements of claim 1 are:
- A device, comprising a processing circuit.
- The processing circuit is configured to automatically generate at least one tag for an image captured using the device.
- This generation occurs in response to analyzing data associated with the image at a time of image capture.
- The device also comprises a memory circuit configured to store the tag with the data to thereby categorize the image.
- The complaint alleges infringement of "at least Claim 1," reserving the right to assert other claims ('555 Patent, Compl. ¶21).
U.S. Patent No. 8,350,928 - "Method and Apparatus for Automatically Categorizing Images in a Digital Camera"
- Patent Identification: U.S. Patent No. 8,350,928, "Method and Apparatus for Automatically Categorizing Images in a Digital Camera", issued January 8, 2013.
The Invention Explained
- Problem Addressed: Like its sibling patents, the ’928 Patent addresses the need for an improved system for the "automatic analysis and categorization of images in an electronic imaging device" to overcome inefficient manual sorting ('928 Patent, col. 1:33-35, col. 2:1-6).
- The Patented Solution: The patent describes a digital camera with an internal "analysis module" coupled to the main processor ('928 Patent, Abstract). This module is configured to analyze image data "at the time of image capture" by tapping into the image processing stream at specific points (e.g., an "RGB insertion point") to generate and store a category tag with the image data ('928 Patent, col. 2:26-34; Fig. 10). The specification discloses that such analysis can be based on detecting characteristics like flesh tones or large amounts of green to identify categories like "people" or "nature scenes" ('928 Patent, col. 6:40-47).
- Technical Importance: By defining specific "plug-in" points for analysis within the image processing pipeline, the invention provided a specific technical architecture for achieving real-time, on-device image categorization.
Key Claims at a Glance
- The complaint asserts independent claim 1 ('928 Patent, Compl. ¶31). A Certificate of Correction was issued for this patent to change the term "preformed" in claim 1 to "performed" ('928 Patent, Cert. of Correction).
- The essential elements of claim 1 are:
- A digital camera for automatically categorizing captured image data.
- The camera comprises a processor for capturing image data.
- The camera comprises an analysis module coupled to the processor.
- The analysis module is configured to perform image data analysis on the captured image data at the time of image capture.
- The module automatically generates, responsive to the analysis, a category tag for the image data.
- A memory for storing the generated category tag in association with the captured image data.
- The complaint alleges infringement of "at least Claim 1," reserving the right to assert other claims ('928 Patent, Compl. ¶32).
U.S. Patent No. 8,836,819 - "Method and Apparatus for Automatically Categorizing Images in a Digital Camera"

Based on detecting this characteristic, the device automatically generates and attaches a category tag to the image file, which is then stored in memory (’819 Patent, Claim 1).
Asserted Claims
Independent claim 1 is asserted (Compl. ¶43).
Accused Features
The accused features are the cameras' processor, which is alleged to capture images of moving objects and categorize them, and the cameras' local storage for the images and associated tags (Compl. ¶¶48-49).
U.S. Patent No. 9,363,408 - "Method and Apparatus for Automatically Categorizing Images in a Digital Camera"
- Patent Identification: U.S. Patent No. 9,363,408, "Method and Apparatus for Automatically Categorizing Images in a Digital Camera", issued June 7, 2016.
Technology Synopsis
This patent claims a method where a first processing device analyzes image data at capture time to generate and store an image category tag. Subsequently, either the first processing device or a second one uses that stored tag to "automatically determine" a category for the image (’408 Patent, Claim 1). This patent focuses on both the generation and subsequent use of the tag for categorization.
Asserted Claims
Independent claim 1 is asserted (Compl. ¶54).
Accused Features
The accused features include the cameras' processor for categorizing images (e.g., as a person, car, or animal), its local storage, and its use of face recognition technology to identify specific people (Compl. ¶¶59-62).
III. The Accused Instrumentality
Product Identification

Identified Points of Contention
- Scope Questions: A primary dispute may arise over the meaning of "at a time of image capture." The patents' shared specification describes analysis occurring at specific "insertion points" within the image processing pipeline before a final image file is compressed and saved ('928 Patent, Fig. 10). The question for the court will be whether the accused products' real-time analysis, which may be architecturally different, falls within this potentially narrow temporal scope.
- Technical Questions: The complaint alleges that detecting a "person, car, or animal" satisfies the "analyzing data" and "generate... a tag" limitations. A technical question is what evidence demonstrates that this functionality is equivalent to the analysis described in the specification, such as detecting flesh tones, green content, or hard edges ('928 Patent, col. 6:40-51). The court will need to determine if the accused functionality is merely a generic object detection or if it performs the specific type of content-based analysis and tag generation claimed.
V. Key Claim Terms for Construction
"at a time of image capture"
Context and Importance
This temporal limitation is present in the independent claims of all four asserted patents and appears to be a cornerstone of the claimed invention, distinguishing it from post-capture categorization software. Its construction will be critical for determining whether the accused products, which perform real-time analysis, actually practice the invention within the specific timeframe required by the claims.
Intrinsic Evidence for Interpretation
- Evidence for a Broader Interpretation: The specification states that "analysis modules may readily analyze image data at any other time or insertion point within the camera" ('928 Patent, col. 8:30-32), which could suggest the term is not rigidly fixed to a single moment.
- Evidence for a Narrower Interpretation: The specification's preferred embodiments and Figure 10 heavily emphasize analysis occurring at specific "RGB" and "YCC" insertion points within the image processing pipeline, prior to compression and final file formatting ('928 Patent, col. 8:12-24; Fig. 10). This may support a narrower construction limited to the period during active image processing and before the image is fully stored.
"analysis module" (’928 Patent, Claim 1)
Context and Importance
This is a key structural limitation in the apparatus claim of the '928 Patent. Whether the software and/or hardware architecture of the Netatmo cameras constitutes an "analysis module" as described in the patent will be a central infringement question. Practitioners may focus on this term because it is a "means-plus-function" style limitation in spirit, if not form, and its scope may be tied to the structures disclosed in the specification.
Intrinsic Evidence for Interpretation
- Evidence for a Broader Interpretation: A plaintiff might argue that any software routine or hardware component that performs the function of analyzing image data to generate a category tag should be considered an "analysis module."
- Evidence for a Narrower Interpretation: The specification provides a specific structure for the "analysis module 540," which includes sub-components like a "text category list 610," "combination logic 615," and "analysis algorithms 630" ('928 Patent, Fig. 7). A defendant could argue that to meet this limitation, an accused device must contain a module with a structure corresponding to that disclosed, not just one that achieves a similar result.
VI. Other Allegations
The complaint does not provide sufficient detail for analysis of indirect or willful infringement.
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of temporal scope: Does the limitation "at a time of image capture," as informed by the patent's disclosure of specific insertion points in a processing pipeline, read on the real-time analysis performed by the accused smart cameras, or does the specific architecture of the accused systems place their analysis outside this claimed timeframe?
- A key evidentiary question will be one of technical correspondence: Do the accused cameras' generalized "people, car, and animal detection" features perform the specific "image data analysis" and "category tag" generation as detailed in the patent specification, or is there a fundamental mismatch between the high-level function of the accused product and the specific technical implementation required by the claims?
- A final question will relate to claim differentiation: Given the assertion of four patents from the same family with similar claims, the court will have to closely examine the subtle differences in claim language (e.g., "processing circuit" vs. "analysis module," "generating a tag" vs. "determining a category") to ascertain the unique scope of each patent and whether the accused products infringe each one independently.
