It started with a problem.
The United States Patent Act of 1790 established the first American patent system, authorizing the Secretary of State, Secretary of War, and Attorney General to review and grant patents. The Patent Act of 1836 reorganized the system, creating the Commissioner of Patents position and requiring examination for novelty — determining whether an invention was genuinely new before granting a patent. The U.S. Patent and Trademark Office documents this history. The international Paris Convention for the Protection of Industrial Property (1883) established the principle of reciprocal patent protection between signatory countries.

Patents changed the economics of invention by enabling inventors to disclose their methods without immediately losing their competitive advantage. Before patents, inventors protected their methods through secrecy — keeping processes proprietary to prevent copying. Patents offered the opposite approach: disclose fully, accept the spread of knowledge, and receive a temporary exclusive right in return. This bargain shifted knowledge into the public domain on a known schedule — after the patent expired, anyone could use the method. The patent system generated a body of technical literature that informed subsequent inventors, accelerating technological development beyond what secrecy would have allowed.
What a builder can learn.
Our interpretation: the patent is a specific tool for a specific type of advantage — a novel, non-obvious, and useful invention. It is not suitable for all competitive advantages. Business processes, customer relationships, brand reputation, and accumulated expertise are typically protected better by operational excellence than by patents. For a business builder, the relevant question is whether a novel process or invention is the source of competitive advantage and whether the advantage would be lost if competitors could copy the method before the market was fully developed.
A door still open.
A hypothesis worth testing: if a small business assessed its most important competitive advantage and asked whether that advantage would persist if competitors could copy the method tomorrow, the answer would reveal whether the advantage was based on something that could be patented, or something — customer trust, accumulated skill, brand familiarity — that could not be copied even without patent protection.
What is the source of your competitive advantage — and if a competitor copied your exact method, how long would it take them to match your position in the market?
