Samsung Electronics - Electronic Device Encrypted Content Decryption Method

The USPTO published Samsung Electronics Co., Ltd.'s patent application US20260100829A1 for an electronic device and control method involving encrypted content decryption. The method includes receiving playback schedule information with disclosure restrictions and validity periods, identifying encrypted content, transmitting decryption requests to a server, receiving encryption keys, decrypting content, and displaying decrypted content based on validity information.

Overlay Protocol Measures End-to-End Network Latency

USPTO published patent application US20260100901A1 by Pranjal Kumar Dutta disclosing methods for embedding overlay protocol packets within network control protocols to measure and calculate end-to-end latency. The invention provides a generic solution for determining latency of network control protocol messages across the entire network path, including host layer latencies not captured by IP-layer measurement tools.

Encrypted Segment Routing in Multi-Region Fabric Networks

USPTO published patent application US20260100831A1 titled 'Encrypted Segment Routing in Multi-Region Fabric Networks' on April 9, 2026. Inventors Arul Murugan Manickam and Basavaraju Halappa filed the application on October 3, 2024. The patent covers methods for hop-by-hop routing in hierarchical multi-region fabric networks where packets contain unencrypted headers and encrypted segment lists.

Collision Avoidance Network Protocol Priority Mode

The USPTO published patent application US20260100863A1 for a collision avoidance mechanism in communication networks. The invention enables devices operating in a priority mode to receive more than one transmit opportunity within a transmit order sequence if they have a particular priority value, while devices without that priority value receive only a single transmit opportunity. The application was filed on October 6, 2025, and published April 9, 2026.

Unicast Aggregation With Minimal Pipeline Flushing in Wireless Communication Networks

USPTO published patent application US20260100919A1 disclosing methods for unicast packet aggregation in time-slotted multi-hop wireless networks. The invention enables a source node to aggregate unicast packets destined for multiple destinations with the same priority into a single MAC Protocol Data Unit, reducing contention for channel access. The application also describes minimal pipeline flushing techniques allowing earlier scheduling of source nodes.

Honeywell Patent for Decentralized Network Discovery in ICS Environments

Honeywell International Inc. has been granted US Patent Application US20260100892A1 for a decentralized network discovery method and apparatus for industrial control systems (ICS). The invention uses a three-component control network module to capture device attributes, construct switch data tables identifying MAC addresses, and build graphical network topology representations. The system enables visualization of connected network devices and their relationships in industrial communication environments. The patent application was filed on December 10, 2025, and published on April 9, 2026.

Multi-Level Link Aggregation Groups for Network Redundancy

The USPTO published patent application US20260100916A1 titled 'Multi-Level Link Aggregation Groups' filed on December 3, 2024. The application, invented by Shiva Kumar Krishna Rao and Mallikarjuna V. Shivakumar, describes a network device that operates hierarchical link-aggregation groups (LAGs) to provide network redundancy. The device can configure a first LAG comprising a set of links between network devices and a second LAG comprising the first LAG plus a high-capacity link.
