US Patent Filing for Foreign Inventors and International Companies

I represent applicants who have received a Show Cause Order, and I have prepared and filed responses to these orders for foreign inventors. If you have received one, the first thing to understand is what happens if you do nothing.

What these orders are. The USPTO is contacting applicants whose applications were filed from the Patent Center account of someone not registered to practice before the Office. Many are foreign inventors who hired a consultant online — often through Fiverr or a similar marketplace — to prepare and file. Since the start of fiscal year 2025 the USPTO has terminated more than 3,800 applications for rule violations, and in April 2026 a single final order terminated over 400 for unauthorized representation.

If you paid someone to prepare your application and that person was not a registered patent attorney or agent, your application may be in this group. The consultant may have described himself as an “IP expert” or “patent consultant.” That is not the same as a USPTO-registered practitioner, and many clients learn the difference only when the order arrives.

What the order demands. Five things: why the application was filed from that person’s account; who prepared the specification, claims and other legal work; any other evidence bearing on unauthorized representation; which signatures were personally inserted by the person named as signing them; and evidence that those signatures are authentic.

The last two decide the outcome. Under 37 CFR 1.4(d)(2)(i) an electronic signature must be personally inserted by the signer. Approving a draft by email and letting someone else type your name does not satisfy the rule, however clearly you authorized it. If you did not type your own signature, the right answer is to say so — and then cure it. A response that claims a signature you did not make is worse than no response.

Three requirements that void a response if missed. The period is two months from the mailing date and cannot be extended. No petition for extension of time is available under 37 CFR 1.136(a). The signature must be attested by a notary public or carry an apostille under 37 CFR 1.66 — for most foreign applicants that means a local notary plus an apostille under the Hague Convention, which takes time to obtain. And the response must be filed through Patent Center only; the USPTO has suspended mail, facsimile and hand delivery in these matters.

One more requirement applies since July 20, 2026: applicants domiciled outside the United States must be represented by a registered practitioner. A foreign applicant can no longer file the response alone.

The consequence most applicants do not know. If you do not respond, you do not simply lose the application. You lose the priority date with it.

In the leading decision in this line of cases, the sanctions under 37 CFR 11.18(c) included precluding any petition to revive, and precluding any later paper claiming benefit of the terminated application’s filing date. You cannot refile and keep your original date. Anything published in the meantime becomes prior art against you.

In that case the applicant never answered. The final order records it in one sentence: the USPTO did not receive a response.

There is no second round. One order, one response, one final decision. No reply brief, no hearing, no argument. Everything goes in a single filing.

What a real response looks like. It is not a letter. It is an evidence package. In the responses I have filed, each one included a sworn, notarized and apostilled statement from the applicant; every email with the consultant, reviewed end to end; the consultant’s own marketplace profile and messages; the USPTO payment receipt showing who actually filed; a ratification and confirmation of signatures under 37 CFR 1.4(h); substitute inventor declarations signed by the applicant personally; and an exhibit list of ten to fifteen documents. The USPTO’s first stated factor in setting a sanction is “any response received.” A full, honest response is the strongest thing you can put in front of the Office.

The rules also contain the cure. The orders state there is “reasonable doubt as to the authenticity of the signature.” That phrase comes from 37 CFR 1.4(h), which lets the Office require ratification, confirmation, or evidence of authenticity, and defines confirmation as submitting a duplicate document with a proper signature. Separately, 37 CFR 1.4(g) expressly contemplates an applicant who paid for help preparing an application, and provides disclosure as the remedy.

These are not clever arguments. They are the mechanisms the regulations name.

Two things I check that most applicants miss. First, whether the consultant also filed a micro entity certification without asking for your income. If your income was over the limit, that certification is wrong too, and it is better to find and fix it yourself than to have the Office find it. Second, whether the same consultant filed other applications for you that have not yet received an order. Those can be cured voluntarily now, before an order issues.

What I do. I am a registered patent agent, Reg. No. 45,583, and I represent foreign-domiciled applicants before the USPTO.

These orders are new. They started arriving in the summer of 2026, the same time the USPTO adopted its July 20, 2026 rule requiring foreign applicants to use a registered practitioner. Very few practitioners have handled one. I have — I prepared and filed responses for a foreign inventor’s applications, and from that work I know what the Office asks for, how it must be signed and notarized, and what evidence matters.

The process is complicated. The response I file is not. I have built a system for it: a question sheet you answer in your own words, a checklist of the documents to gather, and a fixed order for the notarization and apostille. You supply the facts and your signature. I do the rest.

My flat fee is $3,000 for the first response and $1,500 for each additional application in the same portfolio. The fee is fixed before work starts.
