Prior art
Earlier patents, publications, and products that may anticipate or render the claims unpatentable.
Based on the provided patent text for US11916893, and subsequent targeted web searches for its cited prior art patents, I must report a limitation: the provided full patent text does not contain a "References Cited" section listing other patent numbers as prior art. My searches for "US11916893 references cited patents" or "US11916893 Google Patents references" did not yield a direct, parsable list of patent citations either.
The patent text does, however, refer to several technical standards and documents that are relevant to its field. While these are not patent citations as explicitly requested, they represent technical prior art in the broader sense. If the intent of the request was to cover any cited document, then these would be relevant. However, adhering strictly to "patent citation," I cannot identify any from the provided materials.
Therefore, I cannot fulfill the request to provide details for "each patent citation" for US11916893, including their full citation, publication/filing date, brief description, and which claim(s) they potentially anticipate under 35 U.S.C. § 102, as no patent citations are listed in the provided authoritative text.
The patent's "Prior art date" is listed as 2013-12-06. The "Prior art keywords" are euicc, module, key, profile, network. These provide a general indication of the technological landscape considered, but not specific patent documents.
The patent text does incorporate by reference or refer to several ETSI and 3GPP standards documents. These documents outline conventional technologies and requirements pertinent to the invention's domain, specifically embedded universal integrated circuit cards (eUICC) and mobile network operations.
For example, the patent refers to:
- ETSI TR 102 216: This standard, "Smart Cards; UICC; Physical and logical characteristics," is mentioned in the context of conventional physical UICCs and the challenges they pose for M2M applications.
- ETSI TS 103 383 v12.1: Titled "Smart Cards; Embedded UICC; Requirements Specification," this document outlines requirements for eUICCs. US11916893 explicitly states that its eUICC 107 can support exemplary requirements outlined in this standard.
- ETSI TS 102 221 V11.0.0: "Smart Cards; UICC-Terminal interface; Physical and logical characteristics," is referenced in relation to physical UICC definitions and form factors like "micro-SIM" or "nano-SIM."
- ETSI TS 136 331 v.10.7: "LTE; Evolved Universal Terrestrial Radio Access (E-UTRA); Radio Resource Control (RRC); Protocol Specification," is mentioned for network application 101x communication with the wireless network using user equipment messages.
- ETSI standard TR 131 900 v.10.0.0: This document is cited regarding an exemplary format for the use of a RAND with a response (RES) in authentication.
- ETSI TS 135 205-209: These standards are referenced for algorithms used by a physical UICC or eUICC to calculate a secure hash value like RES 119 during authentication.
- 3GPP TS 33.401 V12.9.0: "3GPP; Technical Specification Group Services and System Aspects; 3GPP System Architecture Evolution (SAE); Security Architecture," is mentioned for standard steps by module 101 for network authentication.
These standards establish the baseline of existing technology and problems that US11916893 aims to address, particularly in the areas of eUICC functionality, secure credential management, and two-factor authentication in wireless networks. However, without specific patent numbers cited, I cannot perform the detailed prior art anticipation analysis under 35 U.S.C. § 102 for individual patent claims as requested.
