    • Priority Date: 2015-07-28 [cite: US10379301B2]
    • Brief Description: This patent describes an optomechanical assembly for a photonic chip. [cite: US10379301B2]
    • Potential Anticipation (35 U.S.C. § 102): This reference's focus on an "optomechanical assembly for a photonic chip" could be relevant. If the photonic chip is an AWG and the assembly includes the specific reflective coupling to optoelectronic diodes as claimed in US10379301, it could be a strong candidate for anticipation of claims 1 and 7.

    • Full Citation: US20170187462A1, Multi-channel parallel optical transceiver module [cite: US10379301B2]
    • Publication Date: 2017-06-29 [cite: US10379301B2]
    • Priority Date: 2015-12-23 [cite: US10379301B2]
    • Brief Description: This publication describes a multi-channel parallel optical transceiver module. [cite: US10379301B2]
    • Potential Anticipation (35 U.S.C. § 102): This reference is very close in title and subject matter ("Multi-channel parallel optical transceiver module"). It needs to be carefully examined. If its receiving section discloses a carrier, light receiving chip, arrayed optoelectronic diodes, an optical fiber connector, an AWG with an output end having a top surface at a predetermined angle (41-46 or 42 degrees), and the reflection of signals to the diodes arranged as in claims 1 and 7, it could potentially anticipate these claims.

  • US20170248763A1

    • Full Citation: US20170248763A1, Optical transceiver with fiber tray securing inner fiber [cite: US10379301B2]

    • Priority Date: 2016-02-29 [cite: US10379301B2]
    • Brief Description: This publication describes an optical transceiver with a fiber tray for securing an inner fiber. [cite: US10379301B2]
    • Potential Anticipation (35 U.S.C. § 102): The focus here seems to be on fiber management within a transceiver. It is unlikely to anticipate the specific optical coupling and detection features of US10379301.

  • US20170307819A1

    • Full Citation: US20170307819A1, Techniques for direct optical coupling of photodetectors to optical demultiplexer outputs and an optical transceiver using the same [cite: US10379301B2]
    • Publication Date: 2017-10-26 [cite: US10379301B2]
    • Priority Date: 2016-04-25 [cite: US10379301B2]
    • Brief Description: This publication describes techniques for direct optical coupling of photodetectors to optical demultiplexer outputs and an optical transceiver using these techniques. [cite: US10379301B2]
    • Potential Anticipation (35 U.S.C. § 102): This reference is highly relevant because it explicitly mentions "direct optical coupling of photodetectors to optical demultiplexer outputs," which is central to US10379301. An optical demultiplexer functions similarly to an AWG. If this publication discloses the direct coupling via a reflective surface at a predetermined angle to an array of photodetectors (optoelectronic diodes) on the same carrier as a light receiving chip, it could potentially anticipate claims 1 and 7. The priority date (2016-04-25) is prior to the filing date of US10379301 (2017-02-14), making it valid prior art. This reference should be thoroughly investigated.

    • Priority Date: 2016-06-28 [cite: US10379301B2]
    • Brief Description: This patent describes an opto-mechanical coupler. [cite: US10379301B2]
    • Potential Anticipation (35 U.S.C. § 102): The priority date of this reference (2016-06-28) is after the priority date of US10379301 (2016-05-23), but before its filing date. For it to be prior art for anticipation, it would need to have been "effectively filed" before the effective filing date of US10379301, and name another inventor. However, even if it is prior art, an "opto-mechanical coupler" is a general component. It is unlikely to anticipate the entire system of claims 1 or 7, but could be relevant for obviousness if it shows a similar coupling mechanism.

    • Brief Description: This patent describes aligning and directly optically coupling photodetectors to optical demultiplexer outputs in a multichannel receiver optical subassembly. [cite: US10379301B2]
    • Potential Anticipation (35 U.S.C. § 102): This reference is highly relevant because its title directly describes "aligning and directly optically coupling photodetectors to optical demultiplexer outputs in a multichannel receiver optical subassembly." This closely matches the core inventive concept of US10379301. The priority date (2013-05-14) is well before US10379301's priority date, making it strong prior art. A detailed review of US9509433B2's claims and disclosure is crucial to determine if it expressly or inherently discloses all elements of claims 1 and 7 of US10379301, including the specific angled output surface of the demultiplexer (AWG) reflecting to the optoelectronic diodes on the same carrier surface with a light receiving chip.

    • Brief Description: This patent describes a receiving optical sub-assembly and its manufacturing method. [cite: US10379301B2]
    • Potential Anticipation (35 U.S.C. § 102): As a "receiving optical sub-assembly," this is directly relevant. The priority date is before US10379301. It needs to be carefully examined to see if it discloses all the features of claims 1 and 7, particularly the AWG with the specific angled output and the direct reflective coupling to the array of optoelectronic diodes on the carrier.

Most Relevant Prior Art for Anticipation:

Based on the titles and brief descriptions, the following references appear to be the most relevant for potentially anticipating claims 1 and 7 of US10379301 under 35 U.S.C. § 102:

  1. US20170307819A1 (Priority Date: 2016-04-25) - Explicitly mentions "direct optical coupling of photodetectors to optical demultiplexer outputs." This could very directly describe the core novelty of US10379301.
  2. US9509433B2 (Priority Date: 2013-05-14) - Also explicitly describes "aligning and directly optically coupling photodetectors to optical demultiplexer outputs in a multichannel receiver optical subassembly." This is a highly similar concept.
  3. US7532783B2 (Priority Date: 2006-10-11) - Mentions "integrated DWDM receivers," which is the functional goal of US10379301. A detailed review is needed to check for the structural specifics.
  4. US7376308B2 (Priority Date: 2003-12-24) - Refers to "Optical off-chip interconnects in multichannel planar waveguide devices," which could describe components like an AWG and its connection to other chips.
  5. US20160149662A1 (Priority Date: 2014-11-20) - Describes a "Planar lightwave circuit active connector," which might integrate demultiplexing and detection.
  6. US9482819B2 (Priority Date: 2013-03-04) - Discusses a "WDM Mux/DeMux on cable," directly addressing the wavelength division aspect.
  7. TWI498621B (Priority Date: 2014-09-12) - Mentions a "Receiving optical sub-assembly," directly relevant to the overall device.

A definitive determination of anticipation would require a full claim-by-claim comparison of US10379301 against the complete disclosures of these most relevant prior art documents. Each and every element of the claims of US10379301 would need to be found, either expressly or inherently described, in a single one of these prior art references.
