Automotive Electronics IP Search

Electrification, Autonomy, Connectivity

The automotive industry is undergoing three simultaneous revolutions — electrification, autonomy, and connectivity — each generating dense, overlapping patent landscapes from both traditional automotive suppliers and technology companies with no automotive history. Bosch, Continental, ZF, Aptiv, Mobileye, NVIDIA, Qualcomm, and every major OEM are filing aggressively, creating complex FTO challenges at every supply chain level.

ADAS — Advanced Driver Assistance Systems

ADAS perception systems combine multiple sensing modalities — LIDAR, radar, camera, and ultrasonic — each with independent patent landscapes. LIDAR technology has split into three main architectures with different IP profiles: mechanical spinning LIDAR (Velodyne-era, now largely expired or accessible through Luminar, Cepton), solid-state MEMS LIDAR (Innoviz, Ouster, MicroVision hold MEMS mirror design patents), and FMCW (frequency-modulated continuous wave) LIDAR enabling simultaneous range and velocity from a single chirped laser pulse — the emerging architecture with the fastest-growing patent activity.

77GHz automotive radar uses FMCW modulation, MIMO virtual aperture (4D radar adds velocity per pixel), and neural network processing of radar point clouds. Continental, Bosch, ZF/TRW, Aptiv, and Veoneer hold dense portfolios. The transition from cascade MIMO radar to single-chip radar SoCs (Texas Instruments AWR, NXP S32R) with integrated ADC, DSP, and communication interfaces is generating new patent activity.

Camera-based perception — the Mobileye approach (Tesla also used it before building in-house) — involves monocular depth estimation, temporal integration across video frames, object detection using CNNs (EfficientDet, YOLO variants), and lane marking detection. Mobileye holds hundreds of patents on its EyeQ chip architecture and vision processing algorithms, creating significant FTO considerations for competing ADAS system developers.

EV Powertrain and Battery Management

The SiC MOSFET-based traction inverter — converting DC battery power to three-phase AC for the traction motor — is the highest-power-density power electronics application in volume production. Patents cover SiC-specific gate driver design (high dV/dt immunity requires negative gate bias; common-source inductance compensation), dead-time optimisation (SiC has different body diode characteristics than silicon), space vector PWM (SVPWM) algorithm variants, thermal interface materials for SiC module packaging, and predictive current control for permanent magnet synchronous motors.

Battery Management Systems (BMS) are the most IP-dense area of EV technology. CATL, BYD, Panasonic/Tesla (jointly developed battery management for Model S/3/X/Y), LG Energy Solution, Samsung SDI, and SK On each hold hundreds of BMS patents covering: cell impedance-based State of Health (SoH) estimation using electrochemical impedance spectroscopy (EIS), adaptive extended Kalman filter (EKF) algorithms for State of Charge (SoC) estimation under varying temperature and aging, active cell balancing topologies (switched capacitor, inductive shuttling) versus passive balancing, and electrolyte formulation for fast-charge compatibility.

V2X — Vehicle-to-Everything Communication

5G NR-V2X (3GPP Release 16) and its predecessor PC5-based C-V2X (Release 14/15) define the cellular technology stack for vehicle communication. The standards war between C-V2X (Qualcomm-backed) and DSRC (IEEE 802.11p, backed by Continental and legacy automotive) has largely been settled in favour of cellular V2X in most major markets — but the IP landscape of both technologies remains active for FTO purposes. Nokia, Ericsson, and Qualcomm hold SEP positions in NR-V2X, while the automotive SEP licensing dispute (who licenses at what level) remains commercially unresolved.
