The user is asking for the most relevant prior art for US patent 7384177. I need to:

Search the USPTO database for patent 7384177. (I will use Google Patents as it often links directly to USPTO data and provides cited/citing information.)
Identify all patent citations listed within US7384177.
For each cited patent, extract:
- Full citation (patent number, title, inventor, assignee, publication/filing dates).
- Brief description of the cited patent's invention.
- Identify which claims of US7384177 are potentially anticipated by the cited patent under 35 U.S.C. § 102. This will require analyzing the claims of US7384177 and comparing them to the description of the cited patent.

Based on the provided patent text, I already have the citation information within the patent itself under the "CROSS-REFERENCE TO RELATED APPLICATIONS" and the "DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS" sections (e.g., U.S. Pat. Nos. 4,897,771 and 5,005,108). I will prioritize these explicit mentions and then look at the "Cited By" and "Prior art keywords" sections on Google Patents for other relevant prior art if needed.

The current date is April 26, 2026, but the request specifies "Current Date: April 26, 2026." which is today.

Let's break down the prior art analysis for each cited patent.

Step 1: Identify all patent citations within US7384177.

From the patent text, specifically the "CROSS-REFERENCE TO RELATED APPLICATIONS" and the "DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS" sections, the following U.S. patents are directly cited:

U.S. Pat. No. 7,160,015 (parent application)
U.S. Pat. No. 6,712,481 (parent application)
U.S. Pat. No. 6,079,838 (parent application)
U.S. Pat. No. 5,613,751 (parent application, also listed under "Priority claimed from US08/495,176")
U.S. Pat. No. 4,897,771
U.S. Pat. No. 5,005,108

I need to focus on these cited patents as the "most relevant prior art". The "Cited By" section lists patents that cite 7384177, which is the opposite of what is requested.

Step 2: For each cited patent, extract full citation, publication/filing date, brief description.

The patent further mentions the use of multiple colored light sources for color or white light output.
Potential Anticipation (35 U.S.C. § 102): US 6,712,481 is a direct parent application of US 7,160,015, which itself is a parent of US 7,384,177. Given the familial relationship and the broad description, this patent likely discloses many of the core features of the assemblies. Therefore, US 6,712,481 potentially anticipates Claims 1-27 of US 7,384,177.

3. U.S. Patent 6,079,838

Full Citation: US 6,079,838, "Light emitting panel assemblies," invented by Jeffery R. Parker, assigned to Solid State Opto Ltd.
Publication/Filing Date: Issued June 27, 2000. The application Ser. No. 08/778,089 was filed January 2, 1997. The earliest priority date claimed is June 27, 1995.
Brief Description: This patent describes light emitting panel assemblies that include a transparent panel for light transmission and a light transition area where one or more light sources are mounted. The invention focuses on efficiently conducting light and controlling its emission through patterns of light-extracting deformities on the panel surface. It also discusses the use of reflective or refractive surfaces to enhance light collection and distribution.
Potential Anticipation (35 U.S.C. § 102): US 6,079,838 is a direct parent application to US 6,712,481, and thus part of the same patent family leading to US 7,384,177. It is highly likely to disclose the fundamental aspects of the light-emitting panel assemblies, including the light transition area, light sources, and light-extracting deformities. Therefore, US 6,079,838 potentially anticipates Claims 1-27 of US 7,384,177.

4. U.S. Patent 5,613,751

Full Citation: US 5,613,751, "Light emitting panel assemblies," invented by Jeffery R. Parker, assigned to Solid State Opto Ltd.
Publication/Filing Date: Issued March 25, 1997. The application Ser. No. 08/495,176 was filed June 27, 1995. This is the earliest priority document for the family.
Brief Description: This patent introduces a light emitting panel assembly comprising a transparent panel that acts as a light guide and one or more light sources. It focuses on controlling light output through light-extracting deformities on the panel surface, allowing for uniform or varied light emission. The patent also discusses the construction of the light input area to efficiently couple light from the source into the panel.
Potential Anticipation (35 U.S.C. § 102): US 5,613,751 is the original parent application from which US 7,384,177 claims priority. It describes the fundamental light-emitting panel assembly concept with light sources, transparent panels, and light-extracting deformities. The tray and secondary reflective/refractive surfaces described in Claims 1 and 15 might be a more refined or specific embodiment of the broader concepts discussed here. However, the core elements of efficiently extracting light from a panel using surface features and light input from sources are likely present. Therefore, US 5,613,751 potentially anticipates Claims 1-27 of US 7,384,177, particularly regarding the general concept of light-emitting panel assemblies with light sources and light-extracting deformities.

5. U.S. Patent 4,897,771

Full Citation: US 4,897,771, "High efficiency light source and illumination system," invented by Jeffery R. Parker, assigned to Solid State Opto Ltd.
Publication/Filing Date: Issued January 30, 1990. Filed November 28, 1988.
Brief Description: This patent describes a high-efficiency light source and illumination system, particularly focusing on methods for efficiently coupling light from a source into a light-transmitting panel. It discusses various types of light sources and methods for maximizing light transmission into the panel and out through controlled extraction features. This patent is referenced in US 7,384,177 as disclosing suitable types of light sources.
Potential Anticipation (35 U.S.C. § 102): This patent predates the priority date of US 7,384,177 and is explicitly incorporated by reference for the types of light sources that can be used. While it focuses on the light sources and their coupling into a panel, it does not appear to explicitly disclose the tray with continuous side walls forming a hollow cavity or secondary reflective/refractive surfaces within the tray as claimed in US 7,384,177 Claims 1 and 15. However, the general concept of efficient light coupling and emission from a panel is present. It would anticipate the element of "at least one light source" and the general idea of an "assembly for controlling light emitted from the assembly." Without a deeper dive into its claims, it's less likely to anticipate the specific structural limitations of the tray and its secondary surfaces. It might serve as prior art for the general concept of light guides and light sources but not for the specific tray structure of Claims 1 and 15.

6. U.S. Patent 5,005,108

Full Citation: US 5,005,108, "Light emitting panel assemblies," invented by Jeffery R. Parker, assigned to Solid State Opto Ltd.
Publication/Filing Date: Issued April 2, 1991. Filed May 22, 1989.
Brief Description: This patent describes a light-emitting panel assembly that uses a light guide with features (e.g., surface treatment, deformities) to extract light uniformly or in a controlled pattern. It focuses on the efficiency of light extraction and uniformity. This patent is referenced in US 7,384,177 as disclosing suitable types of light sources.
Potential Anticipation (35 U.S.C. § 102): Similar to US 4,897,771, this patent is cited for the types of light sources, indicating its general relevance to light-emitting technology. It covers light-emitting panel assemblies with light-extracting features. While it establishes the prior art for general light-guiding panels and light sources, it does not appear to disclose the specific tray structure with continuous side walls forming a hollow cavity or the secondary reflective/refractive surfaces within the tray as defined in Claims 1 and 15 of US 7,384,177. It would anticipate the elements of a "light emitting assembly" including a "sheet, film or substrate overlying the assembly for controlling the light emitted," and the use of "deformities" on the surface for light control. It likely provides a strong basis for anticipation of general light panel concepts, but not necessarily the distinct tray enclosure and internal reflective surfaces.
