Provisional
Secures an early filing date when you have a largely complete prototype or a read on the market, without a formal claim set yet.
Main Practice Areas
U.S. and international patent protection, drafted with care.
As a registered U.S. patent agent, Brian Hyun drafts, files, and prosecutes patent applications so your invention is protected under U.S. law — and, through the PCT, in jurisdictions around the world.
01 — Domestic
U.S. Patent Prosecution
We file directly with the USPTO across most technical fields — electrical, software, mechanical, and chemical. The right type of application depends on how far along your invention is and what you need to protect.
Non-Provisional
The formal application for inventions ready to be protected — establishing enforceable claims against substantially similar products.
Continuations
Uses the same disclosure as an earlier application to pursue additional claims not captured during the original prosecution.
Continuation-in-Part (CIP)
Adds new disclosure to an existing application. New matter takes a new filing date while the original disclosure keeps its earlier one — ideal after an improvement.
Reissue
Corrects an issued patent rendered defective by significant errors, restoring full coverage of the invention without adding new disclosure.
Design & Plant
Design applications protect an invention’s ornamental appearance; plant applications protect distinct plants cultivated and reproduced asexually.
02 — International
International Patents (PCT)
Through the Patent Cooperation Treaty, a single international application can preserve your right to seek protection across member countries. The process unfolds in two phases.
The International Application
Filed through a Receiving Office to WIPO — in our case processed by the USPTO before WIPO review. This stage includes an international prior-art search and a patentability analysis before you proceed to the national stage.
The National Stage Application
Entered in any PCT signatory country, where it is examined as an original non-provisional application originating there. Claims can be amended to meet each jurisdiction’s specific requirements.
