Is a Patent in Another Country Considered Prior Art
Vietnam's Approach to Secret Prior Art
Introduction
Currently, under Vietnam'southward Police on Intellectual Property of 2005, equally amended in 2009 and 2019 ("IP Law"), hush-hush prior fine art cannot exist used in evaluating patent applications. However, an approach to evaluate hole-and-corner prior art has been included, for the first fourth dimension, in the draft amendment of the IP Law. Below is our word of this interesting topic.
Recognition in Other Jurisdictions
Hole-and-corner prior fine art is the proper name given to prior art that, at the time of filing of a new patent application, was not discoverable by the new applicant or not publicly available. It exists as a filed but unpublished application, unavailable to the public until publication. Until that point, just the applicants and the patent examiners of the unpublished awarding know of its existence. Even though it is non discoverable or available to the public, secret prior fine art tin can still be used as a bar for novelty in many jurisdictions. Cloak-and-dagger prior art is not express to situations in which the kickoff applicant and the new applicant are different people; hush-hush prior art applies regardless. There is, all the same, a domestic limitation: Applications filed and not notwithstanding published in a strange state are not considered to be secret prior art.
When the applicants are unlike people, the new applicant has no way of discovering the cloak-and-dagger prior art that exists as a filed and unpublished application of the outset applicant. Regardless of the completeness of the patent search, the previously filed and unpublished application cannot be discovered. At the fourth dimension of filing, the new applicant's invention would seem novel. Later, it would be discovered that the awarding was actually filed afterwards another application for the same invention, barring patentability. This creates defoliation and unfairness among multiple applicants.
1 applicant tin can also file two separate applications at unlike times, in which the afterwards filed awarding claims subject area matters disclosed in the earlier filed application. Thus, the earlier filed application—regardless of its availability to the public—can be used as secret prior art for barring novelty. This is called "self-collision." Some jurisdictions allow for excluding this undercover prior art considering it arose from the same applicant. This is called the anti-cocky-standoff exception. This is favorable to applicants, because otherwise their ain disclosures may result in a bar to novelty in their own subsequent patent applications.
The anti-self-collision exception is not a perfect solution to the bug cloak-and-dagger prior art creates for an bidder filing two patent applications. Normally, the subject matter disclosed in the first awarding could not be subsequently claimed by another political party, because the offset application would exist considered during novelty assessment. All the same, with this exception, that subject affair would not be considered, which could result in an unfair patent term extension for the bidder in jurisdictions employing the anti-self-collision exception. 1 method for solving this situation is requiring a final disclaimer filed with the new awarding, effectively limiting its term to that of the offset application.
In Vietnam
Currently, although in that location is no "cocky-collision" based on surreptitious prior art, the Intellectual Property Office of Vietnam (IP Part) has another method for disqualification of the later on-filed application without using secret prior art. The IP Office targets the later-filed application using Article 91 of the IP Constabulary—the priority principle. The below summary of a case written report may clarify this exercise by the IP Office.
An applicant files two Vietnam applications—a prior application A1 (claiming priority to an unpublished application P1) and a new awarding A2 (claiming priority to an unpublished application P2). The inventions disclosed in A1 and A2 are considered as beingness similar in nature. The timeline of the related application is illustrated here for reference.
Under the current IP regulations, without any secret prior fine art concepts, A1 is not prior art against A2 if P2 is recognized as A2's priority. However, at applied examination, this priority right is refused, creating a situation in which A1 may go a bulwark for novelty of A2. See the below linguistic communication from the IP Law:
" Article 91. Priority principle: An bidder for registration of an invention, industrial blueprint or mark may claim priority on the basis of the commencement application for registration of protection of the subject matter."
In the view of the IP Office, upon publication of A1, information technology becomes publicly known that P1 is the earliest awarding disclosing the A1/A2 inventions. Thus, P2 is invalid as priority for A2 because information technology was not the first application to disembalm the subject matter. Because A2's priority date is invalid, the basis for its novelty assessment is now its filing date. Any published applications tin can be used as prior art that were available to the public before the claimed date. Since A1 was published before A2 was filed, A1 is used equally prior art against A2, resulting in A2 being considered not novel. This priority rule arroyo brings the same effect to the subsequently-filed application equally would the undercover prior art approach.
A New Arroyo
Recently, an approach to add together secret prior art to the adjacent amended version of the IP Police has been drafted. The suggested subpoena and supplement to Article 60.1 of the IP Law reads as follows:
"An invention in the invention registration awarding with a subsequent filing engagement or priority date is considered having lost its novelty if it is disclosed in another invention registration awarding with earlier filing date or priority date merely published on or after the filing date or priority engagement of such invention registration application."
With this amendment, the IP Role would exist able to directly decide novelty over a underground prior art instead of using the current methods of applying the first-to-file rule and objecting straight to the priority claim from an before-filed application that results in a direct/indirect pathway for barring patentability.
This proposed amendment, notwithstanding, is not clear on several details. The language "another invention registration application" does non specify domestic awarding; thus, information technology is a gray area whether the undercover prior art is only a Vietnam application or if information technology is also any overseas patent application. Further, the concept of "secret prior art" is unclear for PCT applications electing Vietnam but not actually entering the national stage in Vietnam. Finally, the amendment does non specify whether this subpoena applies to utility solution applications in addition to invention applications. Hopefully, further bylaws guiding the amendments of the IP Police force volition address the in a higher place unclear points.
Adopting this amendment would bring Vietnam into the large grouping of jurisdictions that recognizes secret prior art.
