Patent Strategies for Startups: Provisionals, Software, and When to File
March 3, 2026
Why Patents Matter for Startups
A patent is a government-granted right to exclude others from making, using, selling, or importing a patented invention for a limited period (20 years for utility patents from the filing date). For startups with genuinely novel technology, a strategic patent portfolio can create significant competitive advantages — deterring competitors, supporting premium pricing, and representing real value to investors and acquirers.
But patents are expensive, time-consuming, and uncertain. The USPTO examination process takes 2-4 years on average. Prosecution costs (attorney fees through examination) can easily exceed $15,000-$25,000 per application. And there's no guarantee of issuance — a meaningful percentage of applications are rejected or narrowed during examination. For most startups, a thoughtful, strategic approach to patents is far more valuable than a reflexive filing of every idea.
The Provisional Patent Application: Your First Step
The provisional patent application (PPA) is one of the most useful tools in the early-stage startup's legal toolkit. A provisional application is not examined and does not itself become a patent — but it establishes a priority date, which is the date from which patent rights are measured.
Why File a Provisional?
- Cost: Provisionals are significantly less expensive to prepare than full utility patent applications, since they have fewer formal requirements.
- Speed: A provisional can be filed quickly — often in days or weeks rather than months — to capture a priority date before a public disclosure or product launch.
- One year to decide: Filing a provisional gives you 12 months to decide whether to proceed with a full utility patent application (which claims priority back to the provisional's filing date).
- Patent Pending: Once a provisional is filed, the invention can be marked as "Patent Pending," which has marketing value and puts competitors on notice.
What a Provisional Must Include
While provisionals have fewer formal requirements than utility applications, they must include a written description of the invention sufficient to enable someone skilled in the relevant field to make and use the invention. Claims are not required in a provisional, but the disclosure must support whatever claims are later included in the utility application. A poorly drafted provisional that doesn't fully describe the invention provides weak protection and may not support the claims you ultimately want to pursue.
Software Patent Eligibility: The Alice Problem
Software patents are uniquely challenging because of the Supreme Court's 2014 decision in Alice Corp. v. CLS Bank International, which significantly narrowed the eligibility of software and business method patents under 35 U.S.C. § 101. Under the Alice framework, patent claims directed to abstract ideas (including mathematical concepts and methods of organizing human activity) are not patent-eligible unless they include an "inventive concept" that is "significantly more" than the abstract idea itself.
In practical terms, this means that software patents must be carefully drafted to emphasize the technical implementation of an idea — the specific hardware components, the particular algorithmic steps, the way the invention solves a technical problem in a technical way — rather than the abstract concept the software embodies. Getting this right requires experienced patent counsel who understands both the technology and the evolving § 101 case law.
Building a Patent Strategy
For most startups, the right patent strategy involves several key decisions:
1. What is worth patenting?
Not everything novel is worth patenting. The best candidates for startup patent protection are: (1) core technologies that provide genuine competitive differentiation; (2) inventions that competitors cannot easily design around; (3) technologies where patents will be relevant to investor or acquirer due diligence; and (4) processes that competitors would need to use to compete effectively.
2. Provisional first, utility when the technology is mature
For early-stage startups, the standard approach is to file provisionals early (to secure priority dates) and then file utility applications once the technology is sufficiently developed that meaningful claims can be drafted.
3. Trade secrets as an alternative
For some inventions — particularly algorithms, processes, and methods that competitors cannot reverse-engineer from the product itself — trade secret protection may be more valuable than patent protection. Unlike patents, trade secrets never expire, don't require disclosure of the protected information, and can't be designed around (because competitors don't know what they are). The tradeoff is that trade secret protection is lost if the secret is independently discovered or reverse-engineered.
International Patent Protection
U.S. patents only protect against infringement in the United States. For startups with international markets or global competition, international patent protection may be important. The Patent Cooperation Treaty (PCT) provides a mechanism for filing a single international application that preserves rights in over 150 countries, giving applicants time to decide which national patents to pursue before incurring the expense of individual national filings.
