What did securing the modern door lock patent suggest about Martin's expertise in the context of 1880s systemic friction?

Answer

Technical skill and persistent determination

The text notes that the U.S. Patent Office in the late 1880s had a documented history of creating hurdles, often due to bias, for African Americans seeking patents. Therefore, W. A. Martin’s successful acquisition of the patent for the modern door lock in 1889 implies a dual achievement. It required not only the necessary technical skill to devise a novel and patentable security mechanism but also a substantial degree of persistent determination to successfully navigate and overcome the institutional friction inherent in a system not designed for his success. This resilience is described as a critical component of his invention story.
