Prior Art Cited in US12502870:

  1. US5406414A

    • Full Citation: US5406414A - Electrochromic rearview mirror for vehicles with constant light transmitting area
    • Publication Date: 1995-04-11 (Priority Date: 1992-04-27)
    • Brief Description: This patent describes an electrochromic rearview mirror for vehicles that maintains a constant light-transmitting area.
    • Potential Anticipation (35 U.S.C. § 102): This reference broadly covers electrochromic devices in a vehicle context. It could potentially anticipate the general concept of an electrochromic device (Claim 1, preamble) and the use of electrode layers (Claim 1, element "a first electrode layer and a second electrode layer facing the first electrode layer of the electrochromic film"). However, its focus on a rearview mirror with a "constant light transmitting area" doesn't directly address the specific edge cutting and sealing claimed in US12502870, so it is unlikely to anticipate the unique edge protection features of claims 1-6 and 9-10. It could potentially anticipate material choices for electrode layers (claims 11, 12) if it discloses ITO electrodes.

  2. US5818625A

    • Full Citation: US5818625A - Electrochromic rearview mirror incorporating a third surface metal reflector
    • Publication Date: 1998-10-06 (Priority Date: 1997-04-02)
