An International PCT Patent Application protects your invention for 30 months from the earliest filing. If you have an earliest filing, like a US provisional patent application, you must file the PCT within 12 months of the filing date to validly claim priority to the provisional patent filing.
The PCT application is filed with the World Intellectual Property Office (WIPO) through the United States Patent and Trademark Office (USPTO). The official fees include i) a Transmittal Fee covering transmission of the application to WIPO), ii) a Search fee for the search report that is provided as part of the PCT process, and iii) an international filing fee. There are surcharges for filing by paper instead of electronically, and for large applications over 30 pages. The cost of international PCT patent are broken down in the fees below:
Large Entity is more than 500 employees. You can qualify as a micro-entity where you have fewer than 5 patent applications filed with the USPTO and gross income last year of less than $160,971. Attorneys’ fees generally range from $1500 to $4000 based on the amount of review, formatting and supplementary documentation. Of course, if the application is just in provisional format, it may need further materials and a set of claims to be filed as a PCT.
