What does patent protection actually cost a startup?
Provisional versus non-provisional, attorney fees versus government fees, and the multi-year spend curve nobody budgets for.
Ask three patent attorneys what a patent costs and you'll get three ranges, usually because each is quietly answering a different question. So let's separate the pieces, use real numbers, and give you a framework you can actually budget against.
The two filings, and why they cost so differently
Almost every software or hardware company starts with a provisional patent application. A provisional isn't examined and never becomes a patent on its own. What it does is establish a priority date and give you twelve months to file a full application. A well-prepared provisional is a real technical disclosure, not a cover sheet, because a later patent can only claim what the provisional adequately described.
A non-provisional (utility) application is the real thing: examined by the USPTO, and, if allowed, it issues as a patent. It requires formal claims, drawings, and a complete specification, which is why it costs meaningfully more to prepare.
What each actually costs
Two cost buckets exist for every filing: attorney time to prepare it, and USPTO fees to file it. They're independent, and quotes that blur them are where confusion starts.
Attorney preparation
- Provisional: for software and electronics inventions of ordinary complexity, a professionally drafted provisional typically runs in the low thousands of dollars, depending on how much the disclosure needs to be built out from what the inventors provide.
- Non-provisional: a full utility application for comparable subject matter commonly falls in the range of roughly $8,000 to $15,000 in attorney fees, driven by the number of claims, the complexity of the technology, and how much drawing and specification work is required.
One caveat on these ranges: they reflect traditional drafting economics. As AI-assisted drafting tools mature, some of this preparation cost may come down over time, though the strategic and review work, deciding what to claim, how to frame it, and ensuring the disclosure actually holds up, remains judgment of the patent professional and is where most of the value sits. Expect the routine drafting mechanics to get more efficient; expect the strategic layer to stay human.
USPTO fees
Government filing fees are separate and depend on entity size. The USPTO offers reduced fees for small entities and steeply reduced fees for micro entities (most early startups qualify for one or the other). These fees are published and change periodically, so confirm current figures, but they are a modest fraction of the attorney cost at the provisional and filing stage. The larger government costs, issue fees and maintenance fees, come later.
The part nobody budgets for: the multi-year curve
A patent isn't a one-time purchase; it's a spend curve over years. A realistic path for a single invention looks like:
- Year 0: provisional filed.
- Year 1: non-provisional filed (the priority deadline forces this decision).
- Years 2–4: examination. The USPTO usually issues one or more rejections (this is normal, not a failure), and responding to each, called prosecution, carries its own attorney cost per response.
- Issuance: an issue fee, plus, over the life of the patent, three maintenance fees at roughly 3.5, 7.5, and 11.5 years.
Across that curve, a single invention taken from provisional to issued patent commonly totals well into five figures once prosecution is included. Multiply by the number of inventions worth protecting and you see why patent strategy is a budgeting problem, not just a filing decision.
The useful question isn't "what does a patent cost." It's "which inventions justify the multi-year spend, and how do we sequence the filings against our runway." That's a strategy question, and getting it right saves far more than shaving a few hundred dollars off any single filing.
Where a fractional model fits
The costs above are the same whatever engagement model you use; what changes is how the strategic layer around the filings is handled. In the traditional per-matter approach, you engage a firm for each filing and prosecution step, which works well when someone internally, a technical leader, in-house IP counsel, or a GC, owns the ongoing strategy and deadlines between matters. A fractional arrangement changes the shape of the spend by bundling that strategic layer, ongoing strategy, invention harvesting, and portfolio oversight, into a flat monthly fee, with individual filings quoted at fixed fees you approve before work begins. Either way you pay for the filings; the difference is who owns the continuous decision of what to file and when, which is usually where value is created or lost.
