The first study, ARISE Patent Landscape Analysis 1, Solid-State Batteries & CTC, examines solid-state batteries and cell-to-chassis integration as converging, early-stage domains undergoing rapid expansion. Patent activity has accelerated sharply since 2021, signalling a shift from exploratory research to pre-industrial development. The geographic distribution of filings is concentrated across the US, China and Europe, with additional contributions from Asian manufacturing hubs and increasing participation from secondary regions. Filing trajectories indicate three phases, initial groundwork in the late 2000s, system-level scaling in the early–mid 2010s, and intensified recent entry, reflecting rising competitive density. The data confirms a structural transition toward integration of electrochemical innovation with vehicle architecture.

The second study, ARISE Patent Landscape Analysis 2, EV Battery Packs, analyses more than 33,000 patent families and identifies battery packs and modules as a high-growth technological domain. Between 2018 and 2024, publication output increased by 2.47×, with continuous growth in priority filings since 2019, including during the pandemic period. Innovation activity is concentrated across China, the United States, South Korea and Europe, and is structured around thermal management, pack architecture and battery management systems, reflecting core constraints in performance, safety and scalability. The data also shows a clear policy–industry coupling, with a pandemic-era acceleration driven by electrification strategies.

At system level, both analyses highlight convergence across materials, structural design and electronic control, pointing to a transition from component optimisation to integrated battery system engineering. Europe maintains a broad innovation base and a structurally influential role in patent classification, with forward indicators suggesting sustained high patenting intensity driven by recent priority filing peaks.
