The process of obtaining intellectual property protection in multiple countries simultaneously can be a long and arduous task. With every jurisdiction enforcing their own respective legislation, the filing requirements, as well as procedures regarding the post-grant maintenance of IP, can vary greatly between countries.
Various treaties have been introduced across the globe to assist in the facilitation of a more efficient process for world-wide IP protection. The most poignant international conventions that assist in this regard are the Patent Cooperation Treaty (PCT) and the Paris Convention Treaty. Whilst they are different in nature they are closely linked, with states obliged to first become a member of the Paris Convention before they are able to join as a Contracting State of the PCT.
The Paris Convention Treaty was signed in 1883, and among a broad range of common rules, it provides for the right to national treatment and the right to priority. The concept of national treatment is a vital one, and ensures that Paris Convention member states afford the same level of patent protection and legal remedies to international applicants and right holders as they would to state nationals, preventing different countries from treating non-nationals unfavorably in relation to IP protection.
The right to priority is also of great importance, ensuring that if applicants file an initial application in one contracting state, they have a period of 12 months to file an application regarding the same invention in any other member state(s) without forfeiting the novelty of the invention, and retaining the priority date from the moment of first filing.
The PCT, on the other hand, provides for an efficient method for the filing of patent applications in multiple countries simultaneously via an "international" application. The PCT does not provide for an "international patent", since patent protection can only be valid within a given national/regional territorial jurisdiction. Rather, it serves as a basis for further national patent proceedings in the countries of the applicants interest, meaning a patent obtained via the PCT route is still national or regional in nature. Subsequently, it is possible for applicants to file an initial application with a PCT receiving office which acts as a basis for subsequent filings in any other designated PCT member states in which the applicant wishes to file. A patent filed via the PCT will have the same effect in the designated states as if it had been filed directly in that jurisdiction.
On balance, there are advantages when it comes to the consideration of whether to utilize the Paris Convention or PCT routes for patent filing and protection.
Whilst both routes typically include the filing of a local application with an office of first filing to obtain a priority date, the Paris Convention affords a period of twelve months for applicants to assess which countries they wish to file in before having to commence the national route of protection. The PCT route on the other hand, means that applications won't enter the international phase until 18 months from the date of first filing, and typically take up to 30/31 months, depending on the designated jurisdictions, for the entering of the national phase.
As such, the Paris route may be beneficial for those who wish to obtain patent protection in a few countries in a smaller amount of time. On the other hand, the PCT may benefit those who wish to make use of a longer time period before they must fulfil the national requirements of the designated states for protection, and to utilize this time period to estimate the chances of successful registration of the invention.
Moreover, whilst the PCT allows for applicants to further file in all PCT signatory member states stemming from the one international application, applicants must file separate, individual applications in the countries of choice if utilizing the Paris route. Additionally, the formality criteria, international search, preliminary reports and international publications are centralized and standardized by the PCT system, whereas the same is not the case when filing through the Paris Convention. It is worth noting, however, that the formal requirements of each member state designated will still need to be met during PCT national phase entry.
When considering whether to file via the Paris route or the PCT, the costs involved may provide a good indication as to which an applicant should choose. Overall, the fees incurred for the PCT may prove more cost efficient if an applicant wishes to file in several different states at the same time, however the upfront costs related to the PCT are relatively high.
Subsequently, if an applicant is only planning on filing for protection in a small number of countries, the Paris route is likely to prove less expensive than the costlier PCT and therefore more cost-efficient. On the other hand, if an applicant intends to file in multiple countries, the PCT may result in a cheaper outcome by incorporating many of the fees all at once. For context, PCT applications typically incur three fees: an international filing fee of 1,330 Swiss francs; a search fee which can range from approx. 150 - 2,000 Swiss francs (ISA dependent); and a transmittal fee depending on the Receiving Office.
Both the PCT and Paris Convention each offer their own advantages for those considering filing patent applications in more than one jurisdiction.
