A company does not need to be based in the United States to file a U.S. provisional patent application. For foreign startups, a provisional can be a useful way to establish an early U.S. filing date while the technology is still developing.
That said, the process changed in one important respect in 2026. As of July 20, foreign-domiciled applicants generally need a USPTO-registered patent practitioner to represent them before the Office. There is also a separate issue that foreign companies need to address before filing: some countries restrict when inventions developed within their borders can first be filed abroad.
Neither point makes a U.S. provisional impractical; they simply affect the order in which a foreign company should approach the filing. This guide walks through that process step by step.
Step 1: Check whether you can file in the U.S. first
Before preparing a U.S. provisional, determine whether the invention can legally be filed in the United States before it is filed anywhere else. Some countries require inventions made within their territory to be filed locally first or require a foreign filing license before the invention can be filed abroad. Others impose restrictions only on certain technologies or national-security-related subject matter.
The relevant rules may depend on where the invention was developed rather than where the company is incorporated. That matters for distributed teams — a company headquartered in Germany, for example, could have engineers developing different inventions in Germany, the United States, and Singapore, with different filing restrictions potentially applying to each.
The United States has its own foreign-filing restrictions in the opposite direction. Inventions made in the U.S. generally require authorization before they are first filed abroad. A foreign company with U.S.-based engineers should therefore consider U.S. rules as well as the rules in its home jurisdiction.
You do not need to turn every filing into a multinational legal project. But before using a U.S. provisional as the first filing for an invention, confirm that the filing sequence is permitted where that invention was actually developed.
Step 2: Identify the invention, inventors, and owner
Before drafting begins, the company needs to be clear about what it is filing on and who has rights to it.
Define the invention
For a technical company, the invention is rarely the product as a whole. It may be a particular architecture, implementation, technical workaround, manufacturing method, or other solution developed while building the product. The goal is to identify the technical contribution that may actually be worth protecting, rather than starting from a broad description of everything the company has built.
This matters because the provisional needs to describe that invention in enough detail to support the subject matter the company may later want to claim.
Identify the inventors
The inventors are the people who contributed to the conception of the invention being filed. That does not automatically mean every engineer who worked on the product, and it does not necessarily mean the founders. The right group depends on who actually contributed to the inventive concepts that may eventually appear in the claims.
Confirm that the company owns the rights
A foreign company does not need a U.S. subsidiary to file a provisional application, and a company incorporated outside the United States can be named as the applicant. The more important question is whether the company actually owns, or has the right to receive, the inventors' patent rights.
For companies with engineers working across several countries, that may mean checking employment agreements and invention-assignment provisions in the jurisdictions where those engineers work. The goal is to make sure the ownership chain is clear before it becomes an issue during financing, diligence, or enforcement.
Step 3: Hire a USPTO-registered practitioner
As of July 20, 2026, foreign-domiciled patent applicants generally need to be represented before the USPTO by a registered patent practitioner. That practitioner can be either a registered patent attorney or a registered patent agent. For a company filing a provisional application, a patent agent can handle the core USPTO work, including preparing and filing the application.
An application submitted without the required practitioner's signature may still receive a filing date, but that does not mean every paper filed with it will have the intended legal effect. For most companies, relying on that distinction creates unnecessary risk.
Patentext builds the representation requirement into the process. Once your company decides to move forward with an invention, the matter goes to a USPTO-registered patent agent at Patentext Services for preparation and filing.
Step 4: Develop the provisional disclosure
A provisional application does not need the same formal structure as a non-provisional, and it does not need formal claims (though it's still highly recommended, especially if you plan to eventually file in other jurisdictions outside of the United States). But it still needs enough technical detail to support the subject matter the company may want to claim later. This is why product decks, technical blog posts, and internal feature descriptions are rarely enough on their own. They are usually written to explain outcomes, not to preserve the technical detail a patent practitioner will need.
For a technical company, that usually means explaining how the invention works at the implementation level, not just what the product does. The disclosure should capture the technical problem the team encountered, the solution it developed, and the architecture or process that makes the solution work.
It should also cover meaningful alternatives and variations where those are known. A provisional that describes only the exact version shipping today may leave later claims without support if a competitor takes a different implementation path that the team had already considered.
Patentext structures this part of the process before drafting begins. The platform helps technical teams develop the invention record while the details are still fresh, so the practitioner starts with substantive technical material rather than trying to reconstruct the invention through a series of interviews later.
Step 5: File before the invention becomes public
Timing matters because a provisional is often used to establish a filing date before the company says more about the technology publicly. That could include a product launch, conference presentation, technical publication, public demo, detailed website disclosure, or a non-confidential conversation with a potential partner.
U.S. law provides a limited grace period for certain inventor-originated disclosures. Many other jurisdictions do not offer the same protection. That means a disclosure that may leave U.S. rights intact could still damage or eliminate rights elsewhere.
For a company that may eventually want patent protection outside the United States, filing before public disclosure is usually the safer sequence. Grace periods are better treated as a fallback than as the filing strategy.
Step 6: Use the 12 months after filing deliberately
A U.S. provisional application expires 12 months after its filing date. If the company wants to keep the benefit of that date, it generally needs to file a corresponding non-provisional application within that window.
Those 12 months should not be treated as dead time. The product may continue to evolve, and the engineering team may develop improvements that were not included in the original provisional. If those additions matter, the company may need another filing rather than assuming the first provisional automatically covers everything developed afterward.
The company also has time to decide which parts of the invention are commercially important enough to carry forward into the non-provisional application. By the time the 12-month deadline approaches, the goal should be to have a much clearer view of what is worth claiming and what technical material needs to be added.
Patentext keeps that work in the same pipeline rather than treating the provisional as a one-off filing. The original invention record stays available as the technology develops, making it easier to evaluate new material and prepare the non-provisional without rebuilding the disclosure from scratch.
Step 7: Budget for the non-provisional before the deadline arrives
The provisional is usually the first filing, not the full cost of the patent process. If the company wants to keep pursuing U.S. protection, it generally needs to file a corresponding non-provisional application within 12 months. That application is more involved because it includes the claims that will be examined by the USPTO and begins the prosecution process.
It is worth budgeting for that next step when the provisional is filed rather than treating it as a future problem. Patentext charges $3,600 for a U.S. provisional application and $4,700 for the corresponding non-provisional when Patentext prepares the provisional.
The advantage of planning both stages together is not only cost visibility. The practitioner preparing the later application can build from the same technical record rather than starting over with a new intake process just before the 12-month deadline.
Filing U.S. provisionals from outside the United States
For a foreign company, the USPTO submission itself is rarely the difficult part. The important work happens before and after it: confirming that the invention can be filed in the U.S. first, developing the disclosure thoroughly enough to support the filing date, and making sure registered representation is in place under the 2026 rule.
Patentext gives technical companies one process for doing that. Teams develop inventions through the platform, and approved matters move to USPTO-registered patent agents for preparation and filing. Get started →

Frequently asked questions
What does a U.S. provisional patent application actually do?
A provisional application establishes an early U.S. filing date for the subject matter it adequately describes. It is not examined by the USPTO and does not itself become a patent. It generally expires after 12 months.
To keep the benefit of that filing date, the company typically needs to file a corresponding non-provisional application within that period. The important limitation is that the earlier date only applies to subject matter the provisional actually supports. A provisional does not reserve a date for every later version of the product simply because the company filed something describing the general idea.
Does a foreign company need a U.S. subsidiary to file a provisional?
No. A company incorporated outside the United States can file a U.S. provisional patent application and can be named as the applicant without creating a U.S. subsidiary.
The more important question is ownership. The company should make sure it actually owns, or has the right to receive, the patent rights from the people who invented the technology.
