This dataset identifies 186 patent records in scope, published between 2015 and the 2026 cut-off, matching search terms covering air termination, down conductors, rolling sphere method, separation distance, bonding of services, risk assessment and material selection. These are ranked into 186 patent families spread across 54 distinct assignees. The figure will keep growing for the most recent two years as publication catches up with filing, since publication typically lags filing by around 18 months.

The ranking covers 54 assignees, with the leader holding 45 of the 186 records in scope — a much larger share than fifth place, which sits at 10. The top 5 assignees combined hold 48.9% of all records, and the top 10 hold 69.4%, showing a field concentrated at the top rather than evenly distributed. The mix includes wind turbine OEMs, aerospace manufacturers and companies specialising specifically in lightning protection hardware.

F03D, the IPC subclass for wind motors, appears in 45.7% of the 186 records in scope, the largest single technology cluster in this dataset. Wind turbine blades and nacelles are tall, isolated structures with high lightning strike exposure, and blade damage from an unprotected strike is costly to repair, which drives sustained filing around air termination and down-conductor integration specific to turbine geometry. This is distinct from, though related to, general building and aerospace lightning protection claims.
