Patent №: 12323631 – Image or video coding based on quantization-related information. Chroma QP offset info is signaled via palette coding syntax => index parsed based on list size => reduces signaling bits => improves coding efficiency.

Patent №: 12323630 – Signaling method and device for merge data syntax in video/image coding system. Decoder determines prediction mode from bitstream => derives motion info => generates prediction samples => reconstructs samples; mode decision uses a regular merge flag based on CIIP availability.

Patent №: 12323610 – Adaptive color transform performed with prediction coding. Decoder receives bitstream => performs inverse quantization and transform => checks condition => if met, applies inverse color transform by offsetting color components using bit-depth-based shift.

Patent №: 12323581 – Angular intra prediction. Receive coded block info and reference lines => get first offset from table for adjacent line => get second offset for next line => fetch reference samples using offsets => reconstruct current sample from one of the references.

Patent №: 12323360 – Uplink codeword to layer mapping and phase tracking reference signaling. Devices and methods map codewords to transmission layers and transmit phase tracking reference signals to enhance wireless network performance.

Patent №: 12323357 – DMRS overhead adaptation with AI-based channel estimation. A wireless device receives downlink data with a DMRS pattern => uses a neural network to estimate the channel and find the optimal DMRS pattern => reports the optimal pattern back to the network.

Patent №:  12324191 – Transistor gate structures and methods of forming the same. A wireless device receives downlink data with a DMRS pattern => uses a neural network to estimate the channel and find the optimal DMRS pattern => reports the optimal pattern back to the network.

Patent №: 12322658 – Dummy fin with reduced height and method forming same. Form first and dummy fins above isolation => build gate stack over both => recess fin to form cavity and lower dummy fin height => grow epitaxy region in cavity toward dummy fin.

Patent №: 12322376 – Personalized speech query endpointing based on prior interaction(s) involving a specific phrase preceding an endpoint. A personalized endpointing measure uses recent text and user history to decide if a pause means the user has finished speaking or just paused, improving spoken utterance detection.

Patent №: 12321433 – Adaptive guest mode for portable speakers. A method adapts guest mode on a smart speaker by checking device state => disables guest mode if needed => on receiving a query, identifies the speaker => if not enrolled, suppresses the assistant’s response.
