What Does Patent Prosecution Cost in North Dakota?

Why Patent Costs Are Difficult to Quote Upfront

Unlike a flat-fee legal service, patent prosecution involves significant variability. The complexity of the technology, the breadth of prior art, how many office actions the USPTO issues, and the number of claims all affect total cost. Any attorney who quotes you a single firm number without understanding your invention should be viewed with skepticism.

That said, there are well-established ranges you can use for planning purposes — and that is what this article provides.

Understanding the Two Cost Components

Total patent prosecution cost has two components:

1. USPTO government fees: Set by the USPTO, these are required regardless of whether you use an attorney. Small entities (businesses with fewer than 500 employees) qualify for 60% reductions. Micro entities (individuals meeting income and prior filing criteria) qualify for 80% reductions.
2. Attorney fees: Charged by the patent attorney for their professional time. These vary by attorney, firm, and complexity of the work.

Provisional Patent Application Costs

A provisional patent application is a lower-cost first step that gives you 12 months of "patent pending" status. It does not result in a patent by itself — you must file a non-provisional (utility) application within 12 months to claim the provisional's filing date.

• USPTO filing fee (small entity): ~$320
• Attorney fees for preparation: $1,200–$3,500 depending on complexity
• Total range: $1,500–$4,000

Note: A poorly drafted provisional provides little benefit. The provisional's value depends heavily on how thoroughly it describes the invention. An attorney-drafted provisional protects you better when the non-provisional is filed.

Utility Patent Application Costs

A utility patent is the most common type and provides the broadest protection for how an invention works. The prosecution process spans from initial filing through grant, typically 2–3 years.

Phase 1: Application Preparation and Filing

• USPTO basic filing fee (small entity): ~$830–$1,080
• Attorney fees for drafting specification, claims, and drawings: $3,500–$8,000+
• Phase 1 total range: $4,500–$9,000

Phase 2: Examination and Office Actions

• Most applications receive at least one rejection (office action). Responding typically costs $1,500–$3,500 per office action in attorney fees.
• 2–3 rounds of office actions is common for complex technologies.

Phase 3: Allowance and Issue

• USPTO issue fee (small entity): ~$500–$750
• Publication fees: ~$0–$250

Total Utility Patent Cost Range

• Simple/mechanical inventions: $8,000–$12,000
• Moderate complexity (electrical, software): $12,000–$18,000
• High complexity (biotech, chemistry): $18,000–$30,000+

Design Patent Application Costs

Design patents protect the ornamental appearance of a product — not how it works. They are faster to obtain (12–18 months typically) and less expensive.

• USPTO fees (small entity): ~$500–$700
• Attorney fees: $1,500–$4,500
• Total range: $2,000–$5,500

Ongoing Maintenance Fees

Utility patents require maintenance fees paid at 3.5, 7.5, and 11.5 years after grant to keep the patent in force for the full 20-year term. Current USPTO maintenance fees for small entities are approximately $800, $1,800, and $3,700 at each interval.

How to Budget for Patent Prosecution

A practical budgeting approach for North Dakota inventors and businesses:

1. Start with a patentability search and opinion ($500–$1,500) to assess likelihood of success before committing to full prosecution.
2. File a provisional to establish a filing date while you evaluate commercial potential (12 months to decide).
3. Budget the full prosecution cost before filing the non-provisional — surprises during prosecution are stressful and can force poor strategic decisions.
4. Factor in maintenance fees for valuable patents when building long-term IP budgets.
