International inventors, companies & foreign associates
U.S. patent attorney for international clients.
Parti & Oliveira PLLC helps overseas inventors, startups, small businesses, established companies, and foreign patent counsel pursue U.S. patent protection. Work directly with Vik Parti, a USPTO registered patent attorney licensed in Florida and Texas, on U.S. filings, PCT national-stage entry, and examiner responses.
U.S. representation
From filing instructions to examiner review.
First filings and foreign priority
Preparation of U.S. applications, including a first filing or an application claiming priority to an earlier foreign filing. We review the invention, filing history, business objectives, and applicable requirements before recommending a route.
PCT national stage
U.S. national-stage entry from an international application under the Patent Cooperation Treaty. We review priority dates, the application and search record, required materials, translations, and instructions for the U.S. work.
USPTO office actions
Review of examiner rejections and objections, proposed claim amendments, and examiner interviews when appropriate. We explain the response options and their effect on the protection sought before proceeding.
Working together
Clear responsibilities. Direct communication.
For foreign patent counsel
We coordinate with your team on U.S. drafting, examiner responses, and portfolio decisions. At the outset, we agree on responsibilities, who provides instructions, reporting preferences, and approval of proposed claim changes. Advice on other countries' laws remains with appropriately qualified counsel there.
For international inventors and businesses
You receive an explanation of the U.S. work involved, anticipated professional fees, and separate government charges. Where another jurisdiction is involved, we coordinate with appropriately qualified local counsel. Our role is U.S. representation before the USPTO.
For a single company assignment, continuing prosecution, or a proposed transfer of U.S. matters, explore patent counsel for mid-sized and large companies.
Ongoing patent help for your businessWe can work with you remotely and agree on communication arrangements for your time zone. Our communications are in English. If translated materials or language assistance are needed, we discuss arrangements and costs before work begins.
What to include in your first inquiry
- Your name, company or firm if applicable, country, and time zone.
- A nonconfidential technology area and the U.S. help you need.
- Any public application or publication numbers and known filing dates.
- Known deadlines and past or planned public disclosures, launches, or sales.
After conflicts, scope, fees, and acceptance are confirmed, we arrange review of the technical documents and filing record. Keep confidential invention details out of the initial inquiry.
International company teams
U.S. patent counsel for companies outside the United States.
A company can discuss one U.S. patent application, selected pending matters, or a continuing filing program with Parti & Oliveira PLLC. Work directly with Vik Parti, a registered U.S. patent attorney, on application preparation, PCT national-stage entry, and USPTO examiner responses, subject to conflicts, capacity, and acceptance.
Coordinate with the people responsible for the work.
We can coordinate the agreed U.S. assignment with your company’s legal and engineering teams and existing foreign patent counsel. Discuss who provides instructions, the filing history, known dates, reporting preferences, and communication arrangements across time zones. Communications are in English.
The work may involve software and AI or other engineering technologies in the practice. Representation in another country and advice on its laws remain with appropriately qualified counsel there.
Define the U.S. assignment and filing route.
Before a first filing abroad, applicable first-filing, foreign-filing permission, and secrecy requirements should be checked with counsel in the relevant jurisdiction. Our U.S. engagement does not replace that advice. WIPO summarizes national security filing restrictions.
For a pending U.S. application, include a public application number if available and the known deadline in a nonconfidential inquiry. See changing U.S. patent counsel for scope and handover considerations. An inquiry does not transfer deadline responsibility.
U.S. patent questions
Applying from outside the United States.
Can I work with your firm without traveling to the United States?
Yes. We can handle the agreed U.S. patent work remotely for individual inventors, businesses, and foreign patent counsel. You do not need to be based in Texas or Florida. We agree on communication arrangements and confirm conflicts, scope, fees, and acceptance before representation begins.
Do foreign-domiciled patent applicants need a registered U.S. patent practitioner?
Yes. Effective July 20, 2026, the USPTO requires foreign-domiciled patent applicants and patent owners to be represented by a registered patent practitioner for submissions in patent matters. The requirement applies to papers submitted on or after that date, including in applications filed earlier. The USPTO's announcement of the U.S. counsel requirement explains the change.
Domicile is based on an individual's permanent legal residence or an entity's principal place of business, rather than citizenship. Exceptions and procedural details matter: for example, the rule does not create a new practitioner-signature requirement for maintenance-fee payments or assignment recordation. See the USPTO's U.S. counsel FAQs.
Can the United States be my first patent filing?
We can evaluate a first U.S. filing, including provisional or nonprovisional options where appropriate. Before proceeding, any applicable first-filing or foreign-filing restrictions must be checked with counsel in the relevant country. WIPO explains why national security filing rules can affect the route.
How much time do I have after a foreign or PCT filing?
For a direct U.S. utility application, the ordinary foreign-priority period is 12 months from the first foreign filing. The ordinary deadline for U.S. PCT national-stage entry is 30 months from the priority date, or the international filing date if no priority is claimed. These are different routes, not interchangeable deadlines. Designs and some procedures have different rules. We must review the record to confirm your deadline; contact us early.
Can you take over the U.S. part of an existing patent application?
We can evaluate U.S. national-stage entry from a PCT application, filings based on a foreign application, or representation in a pending U.S. application. The appropriate route depends on the application history and remaining time. Identify the earliest claimed filing date, the current stage, and known deadlines in your initial inquiry; we will arrange an appropriate way to review the file.
Does a U.S. patent protect an invention in other countries?
A U.S. patent concerns rights in the United States. Protection in other countries requires the relevant national or regional procedures. A PCT application provides an international filing route; it does not itself produce a worldwide patent. We handle the agreed U.S. work and coordinate with appropriately qualified foreign counsel when other jurisdictions are involved.
How are U.S. fees and payment arrangements handled?
We discuss professional fees, government charges, outside expenses, and the proposed scope before engagement. For suitable matters, you may ask about installment arrangements for professional fees. Clients remain responsible for government charges and outside expenses separately from attorney fees. Availability and terms are agreed in writing; installment arrangements do not extend patent deadlines. Our patent cost and payment guide explains the stages and costs to consider.
For government-fee planning, see USPTO fee reductions for eligible inventors and small businesses.
Tell us the stage of your matter.
Send a nonconfidential summary of the U.S. work needed and any deadline. An inquiry does not establish representation or mean that we are monitoring a deadline. We confirm acceptance before assuming responsibility for the matter.
