Intellectual Property — key takeaways.
1Four IP mechanisms: copyright (auto, life+70), patent (USPTO, 20 yr), trademark (use + renewal, indefinite), trade secret (no registration, indefinite while secret).
2Pick the right tool. Coca-Cola = trade secret. Code = copyright (register before suing). Mechanism choice is strategic, not procedural.
3Open source is a spectrum. MIT/BSD → Apache 2 → GPL v3 → AGPL v3. Each step adds an obligation downstream.
4AGPL closes the SaaS loophole. Network use triggers copyleft. Most commercial deployments avoid AGPL specifically because of this.
5Work-for-hire assigns employee work to the employer by default. IP-assignment clauses in employment agreements can extend this. Read the contract.
6Waymo v. Uber: 14,000 files downloaded before departure = trade-secret theft. Criminal conviction. $245M civil settlement. The taking is the line.
7Cybersquatting: ACPA (US) and UDRP (global). Three elements: confusingly similar mark, no legitimate interest, bad faith.
8Method, not information. Same datapoint via SEC filing = intelligence. Same datapoint via unauthorized access = espionage. The act, not the artifact, determines the ethics.
