Patent Cooperation Treaty (PCT)

PCT PROCESS

How the PCT Process works

The PCT process refers to the international patent application process under the Patent Cooperation Treaty (PCT). The PCT is a treaty that provides a standardized and streamlined approach to filing patent applications in multiple countries. Here are the general steps involved in the PCT process:

Filing of the PCT Application: The PCT application is filed with the World Intellectual Property Organization (WIPO) in Geneva, Switzerland or with the national patent office of a PCT member country. The application must include a written description of the invention, claims defining the scope of the invention, and any necessary drawings.

International Search: After filing the PCT application, an international search is conducted by a competent International Searching Authority (ISA) to determine the prior art (existing patents, patent applications, and other publications) relevant to the invention. The ISA will then issue an International Search Report (ISR) that lists the prior art references and gives an opinion on the patentability of the invention.

International Publication: The PCT application and the ISR are published by WIPO 18 months from the priority date (i.e., the date of the first patent application filing).

International Preliminary Examination: After the ISR is issued, the applicant has the option to request an International Preliminary Examination (IPE). The IPE is conducted by an International Preliminary Examining Authority (IPEA), and its purpose is to provide a preliminary opinion on the patentability of the invention based on the ISR and any amendments made by the applicant.

National Phase: After the IPE, the applicant must enter the national phase in each country where patent protection is desired. This involves filing a national patent application and paying the necessary fees in each country. The national patent office will then examine the application according to its own laws and procedures.

Overall, the PCT process provides a centralized and standardized approach for filing international patent applications, but it does not result in a “worldwide patent” or a “PCT patent.” Instead, the PCT application is used to secure a filing date and to conduct an international search and preliminary examination, which can help the applicant decide whether to pursue patent protection in individual countries.

Benefits of PCT to inventors,

The Patent Cooperation Treaty (PCT) offers several benefits to inventors who are seeking patent protection for their inventions. Here are some of the main benefits of the PCT for inventors:

Extended Timeframe: One of the significant benefits of the PCT is that it provides an extended timeframe for the inventor to decide in which countries to seek patent protection. The inventor has up to 30 months from the priority date to file national patent applications in individual countries, instead of having to file separate patent applications in each country within the typical 12-month period.

Streamlined Process: The PCT process provides a standardized and streamlined approach for filing international patent applications, which can reduce the cost and complexity of the patent application process. By using the PCT, an inventor can file a single patent application with the World Intellectual Property Organization (WIPO) that will be examined by a single international search authority, which can reduce the need for multiple translations of the application.

International Search: The PCT process includes an international search that is conducted by a competent International Searching Authority (ISA). This search can help the inventor to determine the patentability of the invention and identify prior art that may affect the patentability of the invention in individual countries.

International Publication: The PCT application and the International Search Report (ISR) are published by WIPO, which can increase the visibility of the invention and potentially attract licensing or commercialization opportunities.

Delay Costs: The PCT process can also help the inventor to delay the costs associated with filing national patent applications in individual countries, providing the inventor with more time to assess the commercial potential of the invention and secure funding for patent protection.

Overall, the PCT can offer inventors a more cost-effective and efficient means of seeking patent protection for their inventions while providing the inventor with the flexibility to choose in which countries to pursue patent protection.

Overall, an IP law firm can provide inventors with comprehensive and tailored services related to the PCT process, from initial PCT application filing to managing patent portfolios and enforcing patent rights.

Preparing and Filing PCT applications

Preparing and filing a Patent Cooperation Treaty (PCT) application is a complex process that involves several steps. Here are the general steps involved in preparing and filing a PCT application:

Conduct a Patentability Search: Before filing a PCT application, it is advisable to conduct a patentability search to determine whether the invention is novel and non-obvious. This search can help to identify prior art that may affect the patentability of the invention.

Draft the PCT Application: Once the patentability search is complete, the inventor or their legal representative can draft the PCT application. The application should include a description of the invention, at least one claim defining the scope of the invention, and any relevant drawings or diagrams.

Choose a Receiving Office: The PCT application must be filed with a Receiving Office (RO), which can be the national patent office of a PCT member country or the International Bureau of WIPO. The RO will examine the application for formal requirements and assign an international filing date.

Select an International Searching Authority (ISA): Within one month of the international filing date, the inventor must select an ISA to conduct an international search. The ISA will identify prior art relevant to the invention and provide an International Search Report (ISR).

Publish the Application: The PCT application will be published 18 months from the priority date. The publication includes the description of the invention and any drawings, as well as the ISR.

Enter National Phase: Within 30 months from the priority date, the inventor must enter the national phase in the countries where they want to seek patent protection. This involves filing a national patent application in each country and prosecuting the application until it is granted.

It is important to note that preparing and filing a PCT application can be a complex and technical process. Many inventors choose to work with an experienced patent attorney or agent to help them navigate the process and ensure that their application meets all formal requirements.

• International patent search,

An international patent search is a search of prior art that is conducted by an International Searching Authority (ISA) as part of the Patent Cooperation Treaty (PCT) process. The purpose of the international search is to identify relevant prior art, including patents and other publications, that may affect the patentability of an invention.

The international search is typically conducted within a few months of the international filing date of the PCT application, and the search report is generally provided to the applicant within 16 months of the priority date. The search report includes a list of the prior art that was identified, as well as an opinion on the patentability of the invention based on the prior art.

The international search is an important step in the PCT process, as it can help the applicant to assess the potential patentability of their invention and to make informed decisions about whether to pursue patent protection in individual countries. Additionally, the search report can be used to guide the drafting of the patent claims and to identify areas of the invention that may need further development or clarification.

It is important to note that the international search is not a guarantee of patentability, and that further examination may be required before a patent is granted. Nonetheless, the international search is a valuable tool for inventors and companies seeking to protect their intellectual property and to assess the competitive landscape in their field.

• filing national stage applications,

Filing national stage applications is the process of pursuing patent protection for an invention in individual countries following the international phase of the Patent Cooperation Treaty (PCT) process. Here are the general steps involved in filing national stage applications:

Choose the Countries: The first step in filing national stage applications is to choose the countries where patent protection is desired. The PCT application provides a basis for filing national stage applications in over 150 countries.

Translate the Application: In some countries, it may be necessary to translate the PCT application into the local language. The translation requirements vary depending on the country and the type of application being filed.

File the National Stage Application: The national stage application must be filed within 30 months from the priority date. The application must include a complete specification, including claims, as well as any necessary translations and a power of attorney.

Prosecute the Application: Once the national stage application is filed, the applicant must prosecute the application in each country where it was filed. This involves responding to any objections or rejections from the patent office and working with the examiner to ensure that the claims are allowable.

Grant of Patent: If the application is found to be allowable, a patent will be granted in each country where the application was filed. The patent term and scope of protection may vary depending on the country.

Filing national stage applications can be a complex and time-consuming process, and it is important to work with an experienced patent attorney or agent who can guide the applicant through the process and ensure that all requirements are met. Additionally, the costs of filing and prosecuting national stage applications can be substantial, and applicants should carefully consider the potential benefits of patent protection in each country before proceeding.
