Battery technologies

Battery technology lies at the heart of the energy transition, powering everything from electric vehicles to renewable energy storage. But as the sector evolves, so do its challenges. At HGF, we support innovators in navigating a complex and fast-moving IP landscape with tailored, commercially focused strategies.

With technologies ranging from solid-state and sodium-ion batteries to silicon anodes and cobalt-free chemistries, the battery sector is seeing high volumes of patent filings and intense global competition. Drafting patent applications that avoid prior art, and securing meaningful protection requires not only technical expertise but also knowledge of the field’s evolving trends and legal frameworks.

We also advise on freedom-to-operate analyses, which are essential to product launch, yet increasingly complex due to dense patent portfolios and limited public disclosure of manufacturing methods. Whether you’re scaling up solid-state battery production or exploring next-generation chemistries, we help clients protect innovation, manage risk, and lead with confidence in this high-stakes sector.
