Within this 49-record dataset, one assignee leads with 10 records, roughly one-fifth of all filings in scope. The top five assignees together hold 38 records, or 77.6% of the total, so the field is concentrated rather than fragmented. Anyone assessing freedom-to-operate should prioritise a detailed review of that leading group before searching the smaller, long-tail filers.

The dataset centres on restoring damaged turbine blades through welding and related metalworking processes, with search terms spanning laser cladding, single crystal weldability, heat-affected zone control, dimensional restoration, repair-limit determination, and post-weld heat treatment. IPC data shows B23P (general metal working) and F01D (turbines) as the two most common classes, each appearing on roughly six in ten records, with welding-specific B23K present on 40.8%. Alloy composition claims under C22C are comparatively rare at 18.4%, suggesting most patents protect process sequence rather than metallurgical chemistry.

The trend data does not support a stated growth figure: filing activity peaked at 7 records in 2022 but does not show a consistent multi-year climb, and fewer than four complete years remain once the roughly 18-month publication lag is accounted for. The most recent filing years, including 2026, are necessarily understated because not all filings from those years have published yet. Readers should treat any apparent recent dip as a data artefact rather than a real slowdown until later publications catch up.
