Case Timeline

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

U.S. Patent No. 7,046,252 - "Method and system for adaptive color and contrast for display devices," Issued May 16, 2006

The Invention Explained

• Problem Addressed: The patent addresses the limitations of manual display controls. A viewer manually adjusting contrast for a dark, "washed out" image may find the same setting makes a normal image "over-contrasty," and simple electronic adjustments can cause a loss of detail in bright or dark areas of an image (Compl. ¶9; ’252 Patent, col. 1:32-53).
• The Patented Solution: The invention proposes an automated system that analyzes an input image's luma (brightness) characteristics by creating a "luma histogram." Based on this analysis (e.g., determining if the image is predominantly dark, mid-toned, or bright), the system generates a tailored, non-linear contrast adjustment to enhance detail. It then modifies the chroma (color) to preserve the perceived color saturation after the contrast has been altered, with all adjustments happening on a pixel-by-pixel basis (’252 Patent, Abstract; col. 2:35-51). Figure 2 of the patent illustrates the sequential process, from separating luma/chroma components to generating the final modifications (’252 Patent, Fig. 2).
• Technical Importance: The technology provides a method for automatically optimizing display quality based on the specific content of an image, aiming to improve visual quality without requiring user interaction or sacrificing detail (’252 Patent, col. 3:1-5).

Key Claims at a Glance

• The complaint does not identify specific claims, asserting infringement of "one or more claims" (Compl. ¶11). Independent claim 1 is a representative method claim.
• Independent Claim 1 recites a method for adaptive color contrast comprising the key steps of:
  • separating input data into luma and chroma components;
  • collecting luma distribution data;
  • analyzing the luma distribution data;
  • generating an appropriate contrast control response based on the analysis;
  • modifying the incoming luma component based on the response;
  • analyzing the modified luma component; and
  • generating a non-linear chroma correction factor based on the analyzed modified luma component.
• The complaint reserves the right to assert other claims, which could include independent claim 11 (a computer program product claim) or various dependent claims (Compl. ¶11).

III. The Accused Instrumentality

Product Identification

• The complaint does not name any specific accused products. It refers generally to "Exemplary Defendant Products" that are identified in an "Exhibit 2" (Compl. ¶11, ¶13). This exhibit was not filed with the public complaint.

Functionality and Market Context

• The complaint provides no technical description of how the accused products operate. It makes only the conclusory allegation that the products "practice the technology claimed by the ’252 Patent" (Compl. ¶13). The complaint does not contain allegations regarding the products' specific commercial importance or market position.

IV. Analysis of Infringement Allegations

The complaint references, but does not include, claim charts detailing its infringement theories (Compl. ¶13, ¶14). The narrative infringement theory is limited to the assertion that the "Exemplary Defendant Products" practice the claimed technology and "satisfy all elements of the Exemplary ’252 Patent Claims" (Compl. ¶13). No probative visual evidence provided in complaint.

• Identified Points of Contention: Due to the limited detail in the complaint, the primary points of contention are broad and foundational.
  • Evidentiary Question: A threshold issue for the court will be what evidence the Plaintiff can produce to demonstrate that specific, yet-unnamed MediaTek products perform each of the discrete steps recited in the asserted claims.
  • Technical Question: Does the accused technology operate by creating and analyzing a luma histogram to generate a blended, non-linear contrast response, as described in the ’252 Patent’s preferred embodiments, or does it achieve dynamic contrast through a fundamentally different technical process? The answer will be central to the infringement analysis.

V. Key Claim Terms for Construction

The complaint does not provide sufficient detail for analysis of specific infringement disputes that would highlight key terms. However, based on the technology, the construction of the following terms from independent claim 1 will likely be critical.

"analyzing the luma distribution data"

• Context and Importance: This term is the core of the invention's "adaptive" nature. The definition will determine what kind of analysis is required to infringe. Practitioners may focus on this term to dispute whether the accused method performs a comparable analysis to that disclosed in the patent.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The plain language of the claim itself does not specify a particular method of analysis, potentially allowing for a range of analytical techniques (’252 Patent, col. 5:49-50).
  • Evidence for a Narrower Interpretation: The specification repeatedly describes the analysis in specific terms, such as creating a "luma histogram" by dividing the luma range into "overlapping bands" and "counts the number of input luma data values that fall within each of these bands" (’252 Patent, col. 4:32-37). A defendant may argue these descriptions limit the scope of "analyzing."

"generating appropriate contrast control response"

• Context and Importance: This step links the analysis to the resulting image modification. Its construction will define how the accused product must create its contrast adjustment. The dispute may center on whether the accused product's method of generating a response is equivalent to the patent's disclosed method.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The claim uses the general term "generating," which does not, on its face, require a specific mechanism (’252 Patent, col. 5:50-52).
  • Evidence for a Narrower Interpretation: The specification discloses a specific method of "blends the predefined control responses" for different image types (e.g., dark, mid-tone) using "relative luma counts as a blending weight" (’252 Patent, col. 4:51-54). This detailed embodiment could be used to argue for a narrower construction limited to a "blending" process based on predefined templates.

VI. Other Allegations

• Indirect Infringement: The complaint makes no allegations of indirect infringement (induced or contributory). Count 1 is titled "Direct Infringement" (Compl. ¶11).
• Willful Infringement: The complaint does not contain an explicit allegation of willful infringement. However, in the prayer for relief, it requests that the case be "declared exceptional within the meaning of 35 U.S.C. § 285" and seeks an award of attorneys' fees (Compl. p. 4, ¶E.i).

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

1. Evidentiary Sufficiency: The complaint's reliance on conclusory allegations and an unprovided external exhibit raises a primary question of pleading and proof: Can the plaintiff produce sufficient factual evidence to plausibly map the specific functionality of identified MediaTek products to each limitation of the asserted patent claims?

2. Claim Scope vs. Technology: A central substantive issue will be one of technical implementation: Does MediaTek's dynamic contrast technology operate in a manner consistent with the method claimed in the ’252 Patent, particularly regarding the steps of "analyzing the luma distribution data" and "generating appropriate contrast control response," or does it employ a distinct, non-infringing technical approach to achieve a similar end result?
