Cited Prior Art Analysis

1. US6078274A

Full Citation: US6078274A - Touch panel.
Publication Date: 2000-06-20 (Filing Date: 1996-12-27).
Brief Description: This patent describes a touch panel with a touch sheet and a position detection electrode substrate. It focuses on preventing deformation of the touch sheet to improve durability and prevent erroneous operation. The touch sheet includes a transparent electrode and a transparent cover sheet, or a plurality of parallel transparent electrodes. The position detection electrode substrate includes a plurality of parallel transparent electrodes formed on a transparent substrate.
Potential Anticipation (35 U.S.C. § 102): This patent primarily uses transparent electrodes, a characteristic that US8803836 aims to overcome by using metal lines for electrodes (Claim 1, Claim 9). It does not appear to disclose the black metal lines, the specific arrangement of a display panel, or the resin film acting as a polarizing plate, as claimed in US8803836. Therefore, it is unlikely to anticipate Claim 1 or Claim 8 in their entirety, but might disclose basic touch panel structures with substrates and electrodes.

2. US20010043291A1

Full Citation: US20010043291A1 - Screen input type display device.
Publication Date: 2001-11-22 (Filing Date: 2000-05-17).
Brief Description: This application describes a screen input type display device where a touch panel is placed on the front face of a display panel. It mentions a resistive film type touch panel and a liquid crystal display device. It focuses on improving display visibility by addressing reflections. The touch panel has a transparent input electrode and a transparent sensor electrode.
Potential Anticipation (35 U.S.C. § 102): Similar to US6078274A, this document describes touch panels primarily using transparent electrodes. While it concerns combining a touch panel with a display device, it lacks the specific features of metal lines (especially black metal lines), wiring groups, and the resin film/polarizing plate arrangement that define US8803836, particularly Claims 1 and 8.

3. US20020047969A1

Full Citation: US20020047969A1 - Liquid crystal display device.
Publication Date: 2002-04-25 (Filing Date: 2000-08-31).

The specific metal line electrodes, their black color, the wiring group structure, and the external polarizing plate configurations of US8803836 Claims 1 and 8 are not evident from the title and typical scope of such patents.

4. JP2002342014A

Full Citation: JP2002342014A - Touch panel and data acquisition method therefor.
Publication Date: 2002-11-29 (Filing Date: 2001-05-21).
Brief Description: This Japanese patent document is explicitly mentioned in the background of US8803836 as a "patent document 1" that describes a method where a transparent electrode is formed into stripe-shaped electrodes that intersect. The US8803836 patent states that a drawback of this method is the need to decrease line width to increase detection accuracy, leading to high resistance and difficulty in decreasing gaps.
Potential Anticipation (35 U.S.C. § 102): Given its explicit mention and discussion in US8803836 as prior art that led to the problems the current invention solves, JP2002342014A certainly discloses the concept of stripe-shaped electrodes for touch panels. However, it uses transparent electrodes, whereas US8803836 specifically claims metal lines, particularly black metal lines, to address the shortcomings of transparent electrodes (Claim 1, Claim 9). Thus, it does not anticipate the key distinguishing features of US8803836.

5. US6552718B2

Full Citation: US6552718B2 - Contact structure of substrates of touch panel and method of bonding the same.
Publication Date: 2003-04-22 (Filing Date: 2001-01-10).
Brief Description: This patent describes a touch panel with first and second substrates having electrodes and spacers to maintain a gap. It focuses on the contact structure and bonding method to improve durability and prevent short circuits. It uses a transparent conductive film for electrodes.
Potential Anticipation (35 U.S.C. § 102): This patent addresses structural aspects of touch panels, particularly the contact between substrates and the use of spacers. While relevant to the general construction of touch panels, it relies on transparent conductive films and does not appear to teach the use of metal lines, black color, wiring groups, or the specific polarizing plate arrangements as defining features of US8803836 Claims 1 and 8.

6. US20030090803A1

Full Citation: US20030090803A1 - Touch-panel with light shielding peripheral part.

Brief Description: This patent application describes a touch panel with electrodes formed on substrates, aiming to reduce damage during operation. It uses transparent electrodes.
Potential Anticipation (35 U.S.C. § 102): This patent focuses on durability, a problem also mentioned in US8803836 (F: "transparent electrode is liable to be damaged"; G: "degradation of the transparent electrode which brings about the increase of resistance"). However, US20050046622A1 addresses this in the context of transparent electrodes, while US8803836 solves it by using robust metal lines (Description, Advantages (9)). Thus, it does not anticipate the metal line features of US8803836 Claims 1 and 9.

8. US20050139398A1

Brief Description: This patent application describes a touchscreen using a conductive layer of carbon nanotubes, which can be transparent. It aims to provide low resistance and transparency.
Potential Anticipation (35 U.S.C. § 102): While this patent addresses low resistance and conductivity, it uses carbon nanotubes which are typically transparent, in contrast to the opaque metal lines of US8803836 (Claim 1, Claim 9), especially "black in color." Therefore, it does not anticipate the specific material and color of the electrodes in US8803836.

11. US20060274049A1

Full Citation: US20060274049A1 - Multi-layer conductor with carbon nanotubes.

Full Citation: US20090046077A1 - Display device.
Publication Date: 2009-02-19 (Filing Date: 2006-03-08).
Brief Description: This patent application describes a display device, potentially incorporating a touch panel, with a focus on improving optical properties or manufacturing processes. Its abstract mentions a display device having a touch input function and an optical member for protecting the display.
Potential Anticipation (335 U.S.C. § 102): The publication date (2009-02-19) is after the priority date of US8803836 (2009-01-13). Therefore, this document cannot be prior art for anticipation under 35 U.S.C. § 102, unless it has an earlier priority date itself that predates US8803836. Assuming its effective filing date is the stated filing date (2006-03-08), which is prior to 2009-01-13, it could be prior art. However, based on its generic description, it is unclear if it specifically discloses the metal line electrodes (especially black metal lines), wiring groups, or the specific polarizing plate arrangements claimed in US8803836 Claims 1 and 8.

14. US20090086318A1

Full Citation: US20090086318A1 - Polarizing plate, manufacturing method therefor, optical film and image display.

Potential Anticipation (35 U.S.C. § 102): The publication date (2009-04-02) is after the priority date of US8803836 (2009-01-13). As with US20090046077A1, if its effective filing date (2007-09-28) is the relevant date, it could be prior art. This patent is highly relevant to the "polarizing plate" aspect of US8803836 (Claim 1, Claim 3, Claim 8). However, it focuses on the polarizing plate itself, not necessarily its integration into a touch panel with metal line electrodes as described in US8803836. It would not anticipate the entire combination of elements in Claims 1 or 8, particularly the electrode structure.

Summary of Prior Art Relevance:

Most of the cited prior art, especially those published before the 2009-01-13 priority date of US8803836, broadly cover touch panels and display devices, often using transparent electrodes. The US8803836 patent explicitly distinguishes itself by using metal lines (especially black metal lines) for electrodes to overcome the drawbacks of transparent electrodes, such as high resistance, low transmissivity, and degradation.

Therefore, the most relevant prior art for anticipation under 35 U.S.C. § 102 would be those that specifically disclose the use of metal lines as electrodes in a touch panel, particularly with the features of being black in color, arranged in wiring groups, and combined with a display panel and an external polarizing plate as claimed in US8803836.

Based on the titles and brief descriptions available, the following seem to be the most relevant (and chronologically valid) in terms of general touch panel concepts, even if they don't fully anticipate the invention:

JP2002342014A: Directly cited in US8803836 as a conventional method using stripe-shaped transparent electrodes. While it doesn't anticipate the metal lines, it establishes the background of patterned electrodes.
US6552718B2: Describes contact structure and bonding methods for touch panels with electrodes and spacers, which are fundamental components.
US20050046622A1: Addresses durability issues in touch panels, an improvement area for US8803836.
US20060274047A1 and US20060274049A1: Introduce carbon nanotubes as conductive layers in touchscreens. While transparent, they deal with aspects of conductivity and electrode material, which are points of departure for US8803836.

However, none of the cited patents, based solely on their titles and abstracts, definitively appear to disclose all the distinguishing features of the independent claims of US8803836, such as the black metal lines for both first and second electrodes, the wiring groups combining first lines, or the specific arrangement of the polarizing plate on the first substrate at a side opposite to the second substrate (Claim 1), or the organic EL panel combined with a circular polarizing plate (Claim 8). Many cited patents that refer to "display device with touch panel" or "touch panel" use transparent electrodes, which US8803836 explicitly seeks to improve upon.

It is important to note that a full anticipation analysis would require a detailed review of the entire specification and drawings of each cited patent. The above assessment is limited by the available snippets and general understanding of their subject matter.
