Patent strategy for startups: what to file, when to file, and how much to spend

When a startup founder tells me they have a "patent strategy," it usually means one of two things: they filed a provisional last year and haven't thought about it since, or they're planning to file something eventually but haven't started. Neither is a strategy.

A real patent strategy answers four questions: what to file, when to file, how much to spend, and how to build a portfolio that compounds over time. This guide walks through each of those questions using a framework I've applied across hundreds of early-stage companies.

Step 1: Decide what to patent first

Not every innovation is worth patenting. The goal is to identify inventions that are both patentable and strategically valuable — meaning they cover something a competitor would actually want to copy, and something that's genuinely novel enough to survive examination.

A simple evaluation framework:

• Is it novel? Has a quick prior art search turned up anything close? If the space is already crowded, a patent may be hard to get and narrow in scope.
• Is it central to your competitive advantage? Patents on non-core features or workarounds provide weak protection. Focus on what makes your product hard to replicate.
• Does it have business value? Would a competitor's ability to copy this feature meaningfully harm your market position? If not, the patent may not be worth the investment.
• Is it technically describable? Patents require detailed technical disclosure. Inventions that are hard to describe precisely are harder to patent well.

For most early-stage startups, the first patent should cover the core mechanism that makes the product work — the thing that, if a well-funded competitor implemented it, would feel like a direct threat.

Step 2: Understand your patent budget

Patent costs have two components: professional fees and USPTO fees. Both scale with the complexity of your filing and the stage of prosecution.

Here's a rough cost breakdown:

• Provisional application: $2,000–$6,000 in professional fees, plus $65–$325 in USPTO fees (depending on entity size). A provisional is not examined — it simply establishes a priority date and gives you 12 months to file a non-provisional.
• Non-provisional (utility) application: $8,000–$18,000+ in professional fees, plus $320–$1,600+ in USPTO fees. This is the application that gets examined and, if allowed, issues as a patent.
• Office action responses: $2,000–$5,000 per response. Most applications receive at least one office action from the USPTO examiner before allowance.
• Issue fee: ~$500–$1,200 once a patent is allowed.
• Maintenance fees: Paid at 3.5, 7.5, and 11.5 years after issuance. Small entity fees are $450, $1,150, and $1,900 respectively.

Rough total cost to an issued patent, assuming one office action: $15,000–$30,000+ depending on complexity, entity size, and attorney rates.

For most seed-stage startups, the right approach is to file provisionals on the most important inventions, then convert selectively based on how the business develops.

Step 3: Time your first filing

The most important deadline in patent law is the one most founders don't know about until they've missed it: the one-year on-sale bar.

Under U.S. patent law, you have one year from any public disclosure — a demo, a pitch, a product launch, a conference presentation, a press release — to file a patent application covering that invention. After that year, you're barred from filing in the U.S. and immediately barred from filing in most other countries (which have absolute novelty requirements and no grace period at all).

This means:

• File before any public disclosure whenever possible.
• If you've already disclosed publicly, start the clock and file before the year is up.
• For PCT (international) filings, the clock starts earlier — you have no grace period in most countries.

The practical implication: if you're approaching a fundraise, demo day, or product launch, file at least a provisional beforehand. It takes a few weeks to prepare a solid provisional, so don't wait until the week before.

Step 4: Plan your patent family

A single patent rarely provides robust protection. Strong IP portfolios use a family of related applications to create overlapping coverage that's harder to design around.

Key tools for building a patent family:

• Continuation applications: Filed after the parent application is allowed or issued, with new claims covering different aspects of the same invention. You can file multiple continuations from a single parent, as long as you do so while the parent is still pending.
• Continuation-in-part (CIP): Adds new matter to the original disclosure. Used when you've improved the invention since the original filing. New matter gets a new priority date.
• Divisional applications: Required when the USPTO issues a restriction requirement, splitting a single application into multiple filings covering different inventions.
• PCT applications: Preserve the right to file internationally for up to 30 months from the priority date. Expensive to pursue, but essential for companies with global ambitions.

The right time to start thinking about your patent family is when you file your first non-provisional. The claims strategy for the parent application should be designed with future continuations in mind.
