Before filing a patent application in a foreign country, inventors and companies with U.S.-based inventions must consider foreign filing license requirements and export control laws. Failing to obtain a required foreign filing license before filing abroad can result in significant legal consequences, including abandonment of the patent application and potential criminal liability. At PerspireIP, we ensure that our clients comply with these important but often overlooked requirements. This guide explains what you need to know about foreign filing licenses and export controls in the patent context.
Getting the licence right is step one; keeping the downstream foreign deadlines is step two. PerspireIP’s patent docketing service tracks the 6-month 35 U.S.C. 184 window and every national-phase date that follows it, and our freedom-to-operate search checks the markets you are about to enter before you spend on filings.
What Is a Foreign Filing License?
A foreign filing license is permission granted by the USPTO to file a patent application outside the United States before a U.S. patent application has been pending for 6 months. Under 35 U.S.C. 184, any person who makes an invention in the United States must obtain a license from the USPTO before filing a patent application in a foreign country. The purpose of this requirement is to allow the U.S. government to review inventions made in the U.S. and impose a secrecy order if the invention is related to national security before it is disclosed to foreign patent offices.
When Is a Foreign Filing License Required?
A foreign filing license is required whenever you want to file a patent application for a U.S.-made invention in a foreign country within 6 months of the U.S. filing date. This most commonly arises in the context of PCT applications and direct foreign national filings made within the 12-month Paris Convention priority period. The key trigger is where the invention was made — if it was made in the U.S. (or by U.S. nationals in some cases), a license may be required before foreign filing.
How to Obtain a Foreign Filing License
There are two ways to obtain a foreign filing license. First, you can automatically receive a foreign filing license as part of filing a U.S. patent application. When you file a U.S. application (including a provisional), the USPTO reviews the application for national security concerns. If no secrecy order is imposed within 6 months of the U.S. filing date, you automatically have permission to file abroad. Most routine commercial inventions receive this automatic clearance without any action required.
Second, you can petition for a foreign filing license before filing the U.S. application. This is appropriate when you want to file abroad before filing in the U.S., or when you want to file abroad within 6 months of the U.S. filing date without waiting for the automatic 6-month clearance. The petition for a foreign filing license is filed with the USPTO using a specific form, and the USPTO typically grants or denies the petition within 5 business days for routine commercial inventions. The foreign filing license is then included on the filing receipt for the U.S. application.
Consequences of Filing Without a Foreign Filing License
The consequences of filing abroad without a required foreign filing license can be severe. Under 35 U.S.C. 185, any patent obtained in the U.S. on an invention filed abroad without a license is invalid and unenforceable. In addition, the unlicensed foreign filing can result in criminal penalties for the inventor or company. While these criminal penalties are rarely prosecuted for inadvertent violations, the invalidity of the resulting U.S. patent is a real and significant risk that can completely undermine your patent portfolio.
Export Controls and Patent Applications
Beyond the USPTO’s foreign filing license requirement, inventors and companies must also consider U.S. export control laws when filing patent applications internationally. The Export Administration Regulations (EAR) administered by the Department of Commerce’s Bureau of Industry and Security (BIS) and the International Traffic in Arms Regulations (ITAR) administered by the State Department both regulate the transfer of controlled technology to foreign persons and countries — including transfers that occur when a patent application is filed with a foreign patent office or made available to foreign patent agents.
- ITAR applies to defense articles and services listed on the U.S. Munitions List. If your invention is an ITAR-controlled item, filing a patent application abroad or sharing the invention disclosure with foreign patent agents requires a State Department license or applicable exemption.
- EAR applies to dual-use items on the Commerce Control List. Filing a patent application containing controlled technical data with a foreign patent office may require a BIS license or the use of an applicable license exception.
- Many technology areas implicated by patent applications — including encryption, certain biotechnology, advanced materials, and satellite technology — may be subject to export control review before international filing.
Practical Compliance Steps
The following practical steps help ensure compliance with foreign filing license and export control requirements before filing patent applications internationally.
- Always file a U.S. application first and wait 6 months for the automatic foreign filing license before filing abroad.
- If you need to file abroad within 6 months of the U.S. filing, petition for a foreign filing license simultaneously with or before filing the U.S. application.
- Review your invention disclosure for export control applicability, particularly if your invention involves military, aerospace, encryption, or dual-use technology.
- Consult with an attorney experienced in both patent law and export controls if there is any question about whether your technology is subject to export control regulations.
- Document your compliance efforts — maintain records showing that you obtained the required foreign filing license and considered export control requirements before any international filing.
Special Considerations for Companies with Foreign Employees or Facilities
Companies with multinational workforces or research facilities must consider where inventions are made for purposes of the foreign filing license requirement. If an invention is made jointly by U.S. and foreign employees, or if the inventive work occurs in multiple countries, determining where the invention was made requires a factual analysis of where the key inventive steps occurred. PerspireIP can help companies develop internal policies for tracking the location of inventive activity and ensuring appropriate foreign filing license compliance across their global operations.
Foreign Filing License Requirements by Country
The United States is not unusual in policing where a patent application goes first. Roughly 29 jurisdictions impose some form of clearance before a foreign patent filing, and they split into two very different camps. Some countries care about where the invention was made, regardless of who owns it. Others care about who the applicant is — their residence, citizenship, or principal place of business — regardless of where the work happened. Getting that distinction wrong is how otherwise careful teams lose rights.
Jurisdictions that key off the place of invention include the United States, China, Japan, Norway, Spain, Sweden, and Russia. Jurisdictions that key off residency, citizenship, or place of business include the United Kingdom, France, Italy, India, Singapore, Denmark, Finland, Hungary, Bulgaria, Belarus, and Turkey. Several appear on both lists, which is why a single invention can trigger clearance duties in more than one country at once.
How the major jurisdictions compare
United States — 35 U.S.C. 184. Triggered by inventions made in the US. No foreign patent filing within six months of the US filing date unless a license issues. Every US application is treated as including a petition for a license, and the grant is printed on the filing receipt. Penalties under 35 U.S.C. 185 reach invalidity of the resulting US patent, plus fines up to $10,000 and up to two years’ imprisonment.
China — Article 19, Patent Law (2020 amendment). Triggered by inventions or utility models completed in China, including work done by Chinese subsidiaries and joint ventures of foreign companies. A confidentiality examination must be requested from CNIPA before filing abroad; the review typically runs four to six months. Note the renumbering: this provision was Article 20 before the fourth amendment took effect on 1 June 2021, so older memos and checklists citing “Article 20” are out of date. The sanction is severe and not limited to national-security cases — a corresponding Chinese application will be refused, and an already-granted Chinese patent can be invalidated outright.
India — Section 39, Patents Act 1970. Triggered by the applicant being resident in India, no matter where the invention was made. This is one of the strictest regimes in the world. A resident must either file in India at least six weeks before filing abroad, with no secrecy direction under Section 35 in force, or obtain written permission from the Controller. Non-compliance can mean abandonment of the Indian application, revocation of a granted patent, a fine, and up to two years’ imprisonment.
United Kingdom — Section 23, Patents Act 1977. Narrower than the US or Indian rules. A UK resident needs UKIPO authority only where the application relates to military technology or where publication might prejudice national security or public safety. Ordinary commercial inventions need no permit.
France — Article L612-9, Intellectual Property Code. Applies to applicants resident or principally established in France. Either file in France first and observe the statutory waiting period, or submit the draft to the authorities and request written authorisation.
Italy — Article 198, Industrial Property Code. Applies to Italian residents. An international application is acceptable where it claims priority from a national Italian filing made more than 60 days earlier.
Singapore — Section 34, Patents Act 1994. A Singapore resident may not file abroad without the Registrar’s written authority unless a Singapore application for the same invention was filed at least two months earlier.
Because the waiting periods differ — six months in the US, six weeks in India, two months in Singapore, 60 days in Italy — the binding constraint on an international programme is whichever clock runs longest, not whichever office you happen to deal with most often.
Foreign Patent Filing With Inventors in Several Countries
Distributed R&D is where foreign patent filing goes wrong most often. A single application naming a co-inventor in San Jose, one in Shenzhen, and one in Bengaluru can engage US, Chinese, and Indian clearance duties simultaneously — and those three regimes cannot all be satisfied by filing first in any one of them. The US rule follows the invention, China’s follows the invention, and India’s follows the inventor’s residence. A US-first filing does nothing to cure the Chinese confidentiality-examination requirement or the Indian six-week rule.
Three habits prevent nearly all of these failures. First, capture where each inventor was physically working when the invention was conceived and reduced to practice, not merely which entity employs them; remote and seconded staff routinely break the assumption that an employer’s address reflects the place of invention. Second, screen for clearance duties before the first filing is drafted, because almost every regime is impossible to satisfy retroactively without a penalty. Third, sequence deliberately: identify every jurisdiction with a claim on the invention, then choose a first-filing route and timetable that satisfies the longest waiting period rather than discovering it later.
Where a clearance step has already been missed, act quickly rather than quietly. The US offers a retroactive license under 37 CFR 5.25 where the unlicensed foreign patent filing happened through error and without deceptive intent, but it requires a verified statement, a full account of each country and filing date, and evidence that the problem was pursued diligently once discovered. Other regimes, China’s in particular, provide no comparable cure.
Retroactive Petitions When Material Has Already Gone Abroad
Most teams discover the problem after the fact: a PCT request went to a non-US receiving office, or local counsel in Bengaluru or Shenzhen filed a convention application, and nobody checked the filing receipt first. The error is curable. 37 CFR 5.25 lets the USPTO grant permission retroactively, and in practice the Office grants these petitions when the facts are laid out honestly.
The petition has four moving parts. First, a listing of every country in which the unlicensed material was filed. Second, the date the material was filed in each of those countries. Third, a verified statement — an oath or declaration — that does three things: it avers that the subject matter was not under a secrecy order when it went abroad and is not under one now; it shows that permission was sought diligently once the problem was discovered; and it explains the circumstances in factual detail. Fourth, the fee set by 37 CFR 1.17(g).
The third element is where petitions fail. “The filing occurred through inadvertence” is not an explanation; it is a conclusion. Examiners in Licensing and Review want the actual sequence — who gave the instruction, what the docketing system showed, which email crossed which date. Attach the transmittal letter and the instructions to local counsel.
A petition supported by documents reads as a controls failure that has been diagnosed and closed. A petition resting on a bare assertion of error reads as an attempt to paper over a violation, and it invites a request for further information that adds months to the timeline.
Diligence is measured from discovery, not from the original filing. A violation found during diligence three years later and petitioned within a fortnight sits in a far better posture than one discovered quickly and then left while the team debated whether it mattered. Date the discovery in the record and move.
One limit matters: a retroactive grant cures the statutory bar, but it does not undo a secrecy order violation, and it does not help where the material was genuinely sensitive. Those cases need counsel before anything else happens.
Picking a Receiving Office for a PCT Application
The PCT route is where the rule most often bites, because teams think of an international application as filing “nowhere in particular”. It is not. An international application under the PCT is filed at a specific receiving office, and that office’s country is where the filing legally lands.
Filing at the USPTO as receiving office — RO/US — satisfies the US requirement by itself, because the application is filed in the United States. That is the clean path for an invention made in the US, and it is why so many US-origin portfolios default to RO/US even when the applicant has no particular interest in the US search authority.
Filing the same application at RO/EP, RO/CN, or RO/IB is a filing outside the United States. If the invention was made in the US and no permission has issued, that filing is the violation. The fact that it is an “international” application that will eventually enter the US national phase does not save it. The six-month period runs from the US filing date, so an application filed abroad in month two without clearance is exposed even though the applicant always intended to return to the US at month thirty.
RO/IB is the common answer for genuinely multinational inventive teams, because the International Bureau is open to applicants from any contracting state and sidesteps arguments about which national office is competent. It does not, however, dissolve national clearance duties: an invention made partly in China still needs CNIPA review first, and an Indian-resident applicant still needs permission under Section 39.
Check the filing receipt before the international application goes out, not after. For a US-origin case the grant is printed on the receipt, and confirming it takes a minute.
Deemed Exports and the Line Between EAR and ITAR
Patent material is technical data, and moving it is an export even when nothing crosses a border. Two regimes govern it, administered by different agencies under different rules.
The Export Administration Regulations, run by the Bureau of Industry and Security, cover dual-use technology. Under the EAR, releasing technology or source code to a foreign person inside the United States is a deemed export — treated as an export to that person’s most recent country of citizenship or permanent residence. A German national reviewing a draft specification in a conference room in Austin is, as a matter of regulation, receiving an export to Germany. No passport is stamped and no file leaves the building.
The International Traffic in Arms Regulations, administered by the Directorate of Defense Trade Controls at the State Department, cover defense articles and the technical data behind them, enumerated on the US Munitions List. ITAR is stricter, has narrower exemptions, and is where the consequences are most severe. The threshold question is always which list the subject matter sits on: a propulsion component, a night-vision assembly, or certain cryptographic implementations can pull an otherwise commercial filing programme into ITAR.
There is one practical safe harbour worth knowing. Under 15 CFR 734.18(a)(5), sending, taking, or storing unclassified technology or software secured by end-to-end encryption is not an export, reexport, or transfer at all. End-to-end encryption means the data is never in plaintext except to authorised recipients, and merely being able to access material in that encrypted form is not a release.
Handing over the keys, however, is treated much like handing over the data itself. Key custody, not the mere presence of encryption, is the control that actually carries the safe harbour.
Collaboration Tools, Shared Drives and Distributed Inventors
The compliance gap in most modern practices is not the filing; it is everything that happens before it. Disclosure forms land in a shared drive that replicates to a region outside the US. Drafting goes to an offshore vendor. A machine-translation service ingests the specification. An associate in another office is added to the matter in the document system. Each of those is a potential release of technical data, and none of them looks like an export.
Four controls catch most of it. First, keep invention records in a repository whose regional residency you can actually name, and switch off replication to regions you have not cleared. Second, put the encryption safe harbour to work deliberately — end-to-end protection with keys held in the US, rather than a vendor’s at-rest encryption, which does not meet the standard.
Third, gate matter access by nationality where the subject matter may be listed, and make the document system enforce it rather than relying on a reminder in a kickoff email. Fourth, treat vendor onboarding as an export question: a drafting or illustration vendor abroad receives technical data by definition, and the engagement terms should say what they may do with it.
Distributed inventorship deserves its own flag. When a specification is written from contributions made in three countries, every one of those countries may assert a clearance duty, and they will not agree on which one governs. Record where each contribution was conceived at the time, in the invention disclosure itself, rather than reconstructing it from commit history and calendars years later during diligence. That record is cheap to create and nearly impossible to rebuild.
Docketing the Six-Month Clock and the Review Windows
Compliance here is a calendaring problem wearing a legal disguise. Several clocks run at once, and they are not the same length.
The US period is six months from the US filing date, and for the overwhelming majority of applications the grant arrives on the filing receipt within days, closing the question immediately. Docket the six-month date anyway, because the cases that go wrong are the ones where the receipt carried a retained-material notice and nobody read it.
CNIPA’s confidentiality examination is the long pole. That review typically runs four to six months, which means a request filed once the team has already decided to go abroad is a request filed too late. For any invention with Chinese contribution, the review has to start when drafting starts, not when the convention deadline approaches.
India needs its own lead time. A resident applicant seeking permission to file abroad first should lodge the request roughly six weeks ahead of the intended filing, and should not count on a same-week turnaround.
Three habits make this manageable. Record the place of invention as a docket field, not a note — if the system cannot report “every pending case with Chinese or Indian contribution”, it cannot warn you. Trigger the review request from drafting kickoff rather than from a filing deadline. And docket the response, not just the request: a pending review that nobody chases is indistinguishable from one that was never filed.
Teams that hand this to a dedicated function tend to catch it, because the clock belongs to somebody whose only job is clocks. Our patent docketing best practices guide covers how to structure those fields and triggers.
Diligence Red Flags in Acquisitions and Financings
When a portfolio changes hands, this is one of the few defects that can invalidate an otherwise sound US patent, which is why acquirer’s counsel asks about it early and why sellers are so often unprepared. It belongs on every IP due diligence checklist.
Four questions surface the exposure. Where was each invention made, and what contemporaneous record proves it? Does every US filing receipt show the grant, or do some carry a retained-material notice? For each family, which office received the first filing, and on what date relative to the US filing? And where contribution came from China or India, is there a review request and a disposition in the file?
A gap in the answers is not necessarily fatal. The remedy is usually a retroactive petition filed before closing, and a seller who has already petitioned and received a grant converts a diligence problem into a closed item. A seller who discovers the issue across thirty families during the exclusivity period converts it into a price adjustment or an indemnity that survives closing.
The asymmetry is worth stating plainly, because it drives behaviour. The penalty under 35 U.S.C. 185 is loss of the US patent — the very asset being bought. In China the corresponding application is refused, and an already-granted patent can be invalidated outright, which is not limited to national-security subject matter.
These are not fines to be absorbed as a cost of doing business; they are the destruction of the thing sitting on the balance sheet. That is why an hour of record-keeping during drafting is the cheapest insurance in a portfolio.
When a Secrecy Order Issues Under 35 U.S.C. §181
Screening by Licensing and Review has a third possible outcome that most compliance checklists never plan for. The grant can appear on the receipt, the receipt can stay silent while review continues — or a defense agency can read the disclosure, decide that publication would be detrimental to national security, and ask the Commissioner for Patents to impose a secrecy order under 35 U.S.C. §181. Silence is a hold that usually clears. A secrecy order is an affirmative bar, and it changes the economics of the whole family, not just the timing of one filing.
Orders are not uniform. MPEP 120 describes three, and which one lands determines what you may still do. A Type I order — “Secrecy Order and Permit for Foreign Filing in Certain Countries” — actually preserves a route: it permits filing in states that hold reciprocal security agreements with the United States, currently Australia, Belgium, Canada, Denmark, France, Germany, Greece, Italy, Japan, Luxembourg, the Netherlands, Norway, Portugal, the Republic of Korea, Spain, Sweden, Turkey and the United Kingdom. It is the usual order for critical technology with a military or space application under DoD Directive 5230.25.
A Type II order permits disclosure of the technical content in the same manner as any other classified material, but only where the applicant holds a current DoD Security Agreement (DD Form 441), and it tells you the classification level. A Type III general order is the broadest: no disclosure to anyone absent express written consent from the Commissioner, frequently softened by an attached “Permit A” that restores narrow categories of internal use.
Read the order and its permits before you tell the client the international plan is dead. A Type I order with a permit may leave most of the commercially important jurisdictions open, and the difference between “we cannot file anywhere” and “we can file in eighteen countries” is the difference between losing a portfolio and re-sequencing it.
An order runs for one year from its date of issuance and may be renewed for further periods of not more than a year each on notice from a government agency. In practice renewals are routine for as long as the underlying sensitivity lasts, so treat the anniversary as a live docket entry rather than an expiry you can rely on. Nothing lapses automatically in your favour: if you assume the order died at twelve months and file abroad on that assumption, you have violated an order that was quietly renewed.
The sanction is also different, and worse. Where a required clearance was simply missed, §185 puts the resulting US patent at risk of invalidity. Where an order is in force, 35 U.S.C. §182 provides that the invention is held abandoned for disclosure or filing abroad in violation of it. There is no retroactive cure comparable to 37 CFR 5.25 waiting at the end of that road, and the §184 six-month alternative — the provision that rescues so many ordinary late-filing problems — is expressly unavailable while an order stands. The clock argument that works everywhere else in this area does not work here.
Prosecution does not stop. Under 37 CFR 5.3 the application is examined in the normal way, but no patent issues while the order is in force; the case is held at allowance. 37 CFR 5.5 is the route to a permit or a modification when the original terms prove unworkable — a new contractor needs access, a subsidiary needs the data, a partner jurisdiction has been added — and it is an underused filing. Agencies do modify orders on sensible facts.
Because the order is a taking of commercial value, 35 U.S.C. §183 supplies a right to compensation that is routinely left on the table. The applicant, successors or assigns apply to the head of the department or agency that caused the order to issue. That agency may award a sum not exceeding 75 per cent of what it considers just compensation for the damage from the order and for any government use; the balance is recoverable by suit in the Court of Federal Claims or in the district court where the claimant resides.
The window opens when the applicant is notified the application would otherwise be allowable and closes six years after a patent issues on it, while compensation for government use runs from the date of first use. Those dates are the reason to preserve evidence from day one.
Operationally, five steps on the day an order arrives: flag every member of the family as export-blocked and lock the data room; notify each inventor in writing of what they may no longer say, publish or present, which is the same hygiene that protects a trade secret programme; read the permits before standing down the international plan; calendar the renewal anniversary; and open a compensation file capturing the licensing or product revenue the order is costing, because a §183 claim is only as good as the records behind it.
Frequently Missed Edge Cases
A provisional application is a US filing, and it starts the six-month period running from its own filing date. Teams that treat the provisional as a placeholder and the non-provisional as the “real” filing routinely miscalculate the window by a year.
Continuations and divisionals that introduce new matter deserve a fresh look. The original grant covered the subject matter as it then stood; material added later, particularly where it was developed in another country, is not automatically within its scope.
Design applications are covered by the same regime as utility applications. So are utility models abroad — China’s Article 19 expressly reaches utility models completed in China, which catches teams who assume a lower-tier right carries lower-tier obligations.
Employee relocation changes the analysis mid-stream. An inventor who moves from Munich to Boston during drafting can bring the place-of-invention trigger into play for the portion conceived after the move, and the disclosure record is the only thing that will later show the split.
Finally, electing trade secret protection instead of filing does not take you outside export controls. The decision not to file removes the patent bar, but the underlying technical data is still technical data, and sharing it with a foreign national or an offshore vendor is still a release.
USPTO Foreign Filing License: How It Is Granted, Verified, and Remedied
Almost every question we field on this topic is really a question about one office. The license is a national instrument, not an international one, so the practical mechanics are USPTO mechanics — and the single most common misconception is that the license is something you apply for separately. In the overwhelming majority of cases, it is not.
It usually arrives with your filing receipt
Under 37 CFR 5.12(a), the grant is made as part of the ordinary filing-receipt process. When a US application is filed, the Licensing and Review branch screens the disclosure for national-security implications, and if nothing is flagged the filing receipt itself carries the grant — printed on its face with the date of grant. There is no certificate to request and no fee to pay, which is why counsel searching for a foreign filing license USPTO form generally come up empty — no such standalone form exists. A USPTO foreign filing license therefore exists for most applications weeks after filing, and the only thing counsel needs to do is read the receipt and docket what it says.
Verification matters more than people expect, because the grant is conditional on the disclosure that was screened. If the receipt is silent, the application is still under review and nothing may go abroad yet. Where speed is critical — a looming convention deadline, a co-development partner waiting on a specification — 37 CFR 5.12(b) provides a petition route for an expedited license, filed with the fee set in 37 CFR 1.17(g) and a statement of the facts justifying the request. That petition is the only situation in which anyone genuinely “applies for” a US foreign filing license.
The statutory basis — and the six-month alternative
The controlling provision is 35 USC 184. It prohibits filing abroad on an invention made in the United States within six months of a US application unless a license has been obtained — and it is worth reading the second half of the sentence, because 35 U.S.C. § 184 also supplies the alternative. Once six months have elapsed from the US filing date, and provided no secrecy order has issued in the interim, foreign filing may proceed without any license at all. A great many matters that look like a compliance emergency are simply matters where the clock has already run.
The reason to care is 35 U.S.C. §185, which makes the resulting US patent invalid where a required license was neither obtained nor excused. That is the whole exposure: not a fine, not a prosecution delay, but an unenforceable patent discovered at the worst possible moment. The scope rules in 37 CFR 5.15 are the related trap — a granted license covers the subject matter as screened, including amendments that do not add new technical matter, but materially new disclosure needs its own clearance rather than riding on the earlier grant. The MPEP foreign filing license material at MPEP 140 collects this guidance in one place and is the right citation to put in an internal procedure.
Two phrasings worth correcting while we are here. There is no such thing as a WIPO foreign filing license: WIPO administers the PCT and issues no clearances, and filing a PCT application with the USPTO as Receiving Office is treated as a US filing for these purposes. And a foreign filing license patent question is always resolved by the country where the invention was made, not where the applicant is incorporated — which is why patent foreign filing license requirements have to be checked per inventor on a distributed team.
When the license was genuinely missed
A missed license is usually recoverable. Where the foreign filing happened through error and without deceptive intent, 37 CFR 5.25 allows a petition for a retroactive license, supported by a verified statement explaining the circumstances and confirming that no secrecy order was in force. The petition is granted routinely on good facts, which is precisely why it should be filed as soon as the gap is found rather than deferred to diligence — the facts are easiest to establish while the people involved still remember them.
The same analysis repeats in other jurisdictions with different vocabulary and different triggers: section 23 of the UK Patents Act 1977, section 39 of the Indian Patents Act 1970, and the Article 19 confidentiality examination required for inventions made in China. A foreign filing license USA analysis clears the US leg only; a portfolio with inventors in several of those countries needs each leg checked on its own terms. Teams that want this handled as a standing process rather than a recurring fire drill can use our foreign filing support to screen each new disclosure against the right national trigger before anything leaves the building.
Operationally, the cheapest control is a two-line addition to the docketing record for every new US application: capture the filing-receipt date and the licence status printed on it, and set a reminder at the six-month mark from the earliest US filing date. Those two data points answer nearly every question that later arises in diligence, and they answer it from a contemporaneous record rather than from recollection. Where a receipt comes back silent, flag the matter as blocked for export rather than merely pending, because the distinction is what stops a well-meaning engineer from emailing a specification to an overseas colleague while review is still open.
