Prior art

I will search the USPTO database for US patent 12166869. Since I cannot directly access the USPTO database in real-time for comprehensive prior art analysis, I will leverage the information provided about the patent and its citations.

US patent 12166869 is titled "Key derivation for a module using an embedded universal integrated circuit card".

Based on the provided patent text, here's an analysis of potentially relevant prior art:

The patent text itself references several standards and general technologies that represent the state of the art at the time of its priority date (2013-11-19):

• ETSI TR 102 216: This standard is cited as defining ETSI standards for a physical UICC as of 2013. This general reference establishes the baseline for physical SIM/UICC cards and their functionality, which the invention aims to improve upon with eUICCs. While not a patent, it provides context for the problem US12166869 addresses.
• ETSI TS 103 383 v12.1: Titled "Smart Cards; Embedded UICC; Requirements Specification," this document describes the eUICC subscription manager. This is highly relevant as US12166869 deals with key derivation for a module using an eUICC, and the specification for eUICC itself forms a foundational piece of prior art for the concept of an embedded, programmable UICC. It likely anticipates the general concept of an eUICC and its management, which is a core component of the claimed invention. Specific claims dealing with the presence of an eUICC, or a module receiving profiles from an eUICC subscription manager, could be challenged by this specification.
• RFC 786 (User Datagram Protocol) and RFC 793 (Transmission Control Protocol): These IETF RFCs describe fundamental internet protocols. They are general networking standards and would form part of the background art for any communication over IP networks, but would not typically anticipate specific inventive steps related to key derivation or eUICCs. They establish the environment in which the communication takes place.
• X.509 series of standards, including X.509 v3 certificates, and IETF RFC 5280 "Internet X.509 Public Key Infrastructure Certificate and Certificate Revocation List (CRL) Profile": These standards relate to Public Key Infrastructure (PKI) and certificate management. Since US12166869 involves public and private keys and certificates, these standards represent fundamental prior art for the cryptographic primitives and concepts used. Claims involving the use of PKI, generation of key pairs, or certificates for authentication would need to demonstrate novelty beyond these established standards.

Detailed Analysis of Cited Patent References (as available in the provided text):

The patent description itself explicitly mentions its priority is claimed from US14/084,141. This indicates US14/084,141 is a direct predecessor application for US12166869.

• US9319223B2: This patent is explicitly linked as a priority document to US14/084,141, which itself is a priority document for US12166869. Therefore, US9319223B2 is highly relevant prior art.
  • Full Citation: US9319223B2 (This is derived from the "patent/US9319223B2/en" link in the "Priority claimed from US14/084,141" section.)
  • Publication/Filing Date: The priority date for US12166869 is 2013-11-19, and it states "Priority claimed from US14/084,141" which then links to US9319223B2. This implies US9319223B2 would have an earlier effective filing or priority date than 2013-11-19, making it prior art.
  • Brief Description: Without the full text of US9319223B2, a precise description is not possible. However, given its relationship as a parent application, it is highly likely to cover aspects of secure communication, key management, or eUICCs for modules. It probably introduces at least some fundamental aspects of key derivation for modules using eUICCs or related technologies.
  • Potential Anticipated Claims: Given its status as a direct ancestor, it has the potential to anticipate a broad range of claims in US12166869, particularly those related to the core concepts of deriving keys for a module with an eUICC. This could include claims relating to:
    • A module utilizing cryptographic algorithms to generate module keys.
    • A module storing an initial key in a UICC or eUICC.
    • A module deriving a shared secret network key using a key derivation function.
    • A module authenticating with a wireless network using a derived key.

To provide a more exhaustive list of relevant prior art and their specific anticipation under 35 U.S.C. § 102, I would need to perform a full search of the "Prior Art Citations" section of US12166869 on the USPTO website. However, based on the provided text, US9319223B2 is the most directly identifiable and significant piece of prior art due to its explicit citation as a priority source.
