Company patents
Energizer Brands, LLC
Energizer Brands, LLC's patent strategy is heavily concentrated in "Batteries & Fuel Cells," which accounts for 70.1% of its portfolio, yet this core area has seen a consistent decline in patenting activity, with a -53.3% YoY drop so far in 2026. Surprisingly, while several smaller materials-related categories like "Compounds Containing Metals" and "Coating Compositions (Paints, Inks)" have seen significant declines, "Containers & Packaging" is emerging as a new focus with 2 patents in 2026 after no activity in prior years.
