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

Many companies start with a provisional patent application, though it is optional and some file a non-provisional directly. A provisional isn't examined and never becomes a patent on its own. What it does is establish a filing date and give you twelve months to file a non-provisional that claims its benefit. A well-prepared provisional is a real technical disclosure, not a cover sheet: a later claim receives the provisional's filing date only if the provisional adequately describes and enables what that claim covers. The non-provisional can add new subject matter, but claims that rely on the added disclosure ordinarily receive the later filing date.

A non-provisional (utility) application is the real thing: examined by the USPTO, and, if allowed, it issues as a patent. A non-provisional utility application includes formal claims, drawings when necessary, and the other materials required for examination. Both filing types need adequate technical disclosure for the subject matter that relies on their filing dates; the additional preparation cost depends on what work remains.

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: as an illustrative estimate only, for software and electronics inventions of ordinary complexity, a professionally drafted provisional often 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: as an illustrative estimate only, a full utility application for comparable subject matter often falls in the range of roughly $8,000 to $15,000 in US attorney fees (excluding government fees and formal drawings), though actual charges vary by provider and scope, 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, but only if the applicant meets the applicable rules. Eligibility depends on factors such as ownership, affiliations, and licensing relationships, and micro entity status has additional income and filing-history requirements, so confirm it rather than assuming it from company stage. For a non-provisional utility application, government fees include filing, search, and examination fees at filing, an issue fee if the application is allowed, and maintenance fees after grant. These fees are published on the USPTO fee schedule and change periodically, so confirm current figures before budgeting. A provisional requires only a basic filing fee, with no search or examination fees. In aggregate, the later fees, especially maintenance, can be substantial.

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 due at 3.5, 7.5, and 11.5 years after the patent is granted.

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.

Where a fractional model fits

The same broad cost categories apply across engagement models, although amounts, scope, and billing arrangements can differ; what changes most 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 reserved weekly or monthly hours, with larger filing efforts available as fixed-fee engagements 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.
