Global Patent Strategy: The 30-Month Reservation System and Where to File

Global Patent Strategy: The 30-Month Reservation System

For AI, robotics, and semiconductor innovators, a U.S. patent is only the first node of protection. If a competitor can manufacture your chip in Taiwan or deploy your algorithm in China, your domestic filing provides zero leverage.

The challenge for startups is the Capital vs. Coverage tension: You need global rights to justify your valuation, but you cannot afford worldwide filing fees on a seed-stage budget.

The solution is choosing the right vehicle: The PCT System or Direct National Filing.

The PCT Mechanism: Buying Time

The most critical takeaway for founders is that there is no such thing as an international patent. The PCT is a reservation system.

The Benefit: One filing preserves your rights in 157 countries for 30 months.

The Strategic Delay: You defer the massive costs of the national phase (e.g., translations and local counsel) for an additional 18 months.

The ROI: By month 30, you have the Series A funding and market validation to know exactly which jurisdictions are worth the investment.

Direct National Filing: The Targeted Strike

If your market is fixed (e.g., only the U.S. and the UK) and your budget is set, direct filing is more cost-effective. It bypasses the PCT fees and moves you toward a granted patent faster.

Strategic Recommendations for 2026

• Default to PCT for Uncertainty: If you aren't sure which markets will matter in two years, pay for the optionality.

• Never Forget Taiwan: For semiconductor firms, Taiwan is a mandatory node but is NOT a member of the PCT. You must file there directly by the 12-month deadline.

• Audit the AI Lifecycle: European and Asian patent offices have distinct standards for AI eligibility. Your initial drafting must anticipate these global hurdles.

The Bottom Line

Global strategy is not about filing everywhere. It is about filing where protection creates Business Value. By the 28-month mark, you should have the clinical data to decide which markets warrant a $50,000+ investment and which should be abandoned.
