Company patents

Southco, Inc.

Southco, Inc. demonstrates a highly concentrated patent strategy, with Locks & Keys representing nearly 60% of its total portfolio. Despite this dominance, the company shows a surprising shift in focus, as patenting in Locks & Keys saw a significant 66.7% increase in 2025, followed by an 80.0% decline so far in 2026, while other minor categories like Fasteners, Bearings & Shafts, Buildings (Specially Adapted), and Vehicle Body Fittings have seen a complete cessation of patenting activity in 2026 after some intermittent filings in prior years.
