Divisional patent application

Last updated

A divisional patent application, also called divisional application or simply divisional, is a type of patent application that contains subject-matter from a previously filed application, the previously filed application being its parent application. [1] While a divisional application is filed later than the parent application, it retains its parent's filing date, [1] and will generally claim the same priority. Divisional applications are generally used in cases where the parent application may lack unity of invention; that is, the parent application describes more than one invention and the applicant is required to split the parent into one or more divisional applications each claiming only a single invention. The ability to file divisional applications in cases of lack of unity of invention is required by Article 4G of the Paris Convention. [2]

Practice by jurisdiction

The practice and procedure of filing a divisional patent application vary from jurisdiction to jurisdiction. In most countries, the filing of divisional applications is possible at least as long as the parent patent applications are pending. Since 2013, the European Patent Office rules are again in line with the current practice before the patent offices in the U.S., Germany, and Japan. [3]

European Patent Convention

Before the European Patent Office (EPO), divisional applications can be filed under Article 76 EPC. A European divisional application is a new application which is separate and independent from the parent application unless specific provisions in the European Patent Convention (EPC) require something different. [4]

"The procedure concerning the divisional application is in principle independent from the procedure concerning the parent application and the divisional application is treated as a new application... Although there are some connections between the two procedures (e.g. concerning time limits), actions (or omissions) occurring in the procedure concerning the parent application after the filing of the divisional application should not influence the procedure concerning the latter...." [5]

The practice relating to the filing of divisional applications under the EPC was clarified by the Enlarged Board of Appeal of the EPO in June 2007. The Board held that a divisional application which on filing contained subject-matter extending beyond the content of the earlier application as filed could be amended later to remove the deficiency, even at a time when the earlier application is no longer pending. [6]

United States

In the United States, a divisional application is seen as a type of continuing patent application, except that if a restriction requirement necessitated the filing of the divisional application, the law provides protection against a rejection of the application and against invalidation of thus-issued patents for double patenting. [7]

Cascade of divisionals

If a divisional application is filed based on a patent application that is already a divisional application, the newly filed divisional is a second-generation divisional, and so on, "thereby creating a cascade of divisionals". [8]

The European Patent Convention (EPC), also known as the Convention on the Grant of European Patents of 5 October 1973, is a multilateral treaty instituting the European Patent Organisation and providing an autonomous legal system according to which European patents are granted. The term European patent is used to refer to patents granted under the European Patent Convention. However, a European patent is not a unitary right, but a group of essentially independent nationally enforceable, nationally revocable patents, subject to central revocation or narrowing as a group pursuant to two types of unified, post-grant procedures: a time-limited opposition procedure, which can be initiated by any person except the patent proprietor, and limitation and revocation procedures, which can be initiated by the patent proprietor only.

Prior art is a concept in patent law used to determine the patentability of an invention, in particular whether an invention meets the novelty and the inventive step or non-obviousness criteria for patentability. In most systems of patent law, prior art is generally defined as anything that is made available, or disclosed, to the public that might be relevant to a patent's claim before the effective filing date of a patent application for an invention. However, notable differences exist in how prior art is specifically defined under different national, regional, and international patent systems.

In patent law, industrial design law, and trademark law, a priority right or right of priority is a time-limited right, triggered by the first filing of an application for a patent, an industrial design or a trademark respectively. The priority right allows the claimant to file a subsequent application in another country for the same invention, design, or trademark effective as of the date of filing the first application. When filing the subsequent application, the applicant must claim the priority of the first application in order to make use of the right of priority. The right of priority belongs to the applicant or his successor in title.

The EPC 2000 or European Patent Convention 2000 is the version of the European Patent Convention (EPC) as revised by the Act Revising the Convention on the Grant of European Patents signed in Munich on November 29, 2000. On June 28, 2001, the Administrative Council of the European Patent Organisation adopted the final new text of the EPC 2000. The EPC 2000 entered into force on December 13, 2007.

The opposition procedure before the European Patent Office (EPO) is a post-grant, contentious, inter partes, administrative procedure intended to allow any European patent to be centrally opposed. European patents granted by the EPO under the European Patent Convention (EPC) may be opposed by any person from the public. This happens often when some prior art was not found during the grant procedure, but was only known by third parties.

A patent application is a request pending at a patent office for the grant of a patent for an invention described in the patent specification and a set of one or more claims stated in a formal document, including necessary official forms and related correspondence. It is the combination of the document and its processing within the administrative and legal framework of the patent office.

G 1/03 and G 2/03 are two decisions of the Enlarged Board of Appeal of the European Patent Office (EPO), which were both issued on April 8, 2004.

This is a list of legal terms relating to patents. A patent is not a right to practice or use the invention, but a territorial right to exclude others from commercially exploiting the invention, granted to an inventor or his successor in rights in exchange to a public disclosure of the invention.

Double patenting is the granting of two patents for a single invention, to the same proprietor and in the same country or countries. According to the European Patent Office, it is an accepted principle in most patent systems that two patents cannot be granted to the same applicant for one invention. However, the threshold for double patenting varies from jurisdiction to jurisdiction.

<span class="mw-page-title-main">Grant procedure before the European Patent Office</span>

The grant procedure before the European Patent Office (EPO) is an ex parte, administrative procedure, which includes the filing of a European patent application, the examination of formalities, the establishment of a search report, the publication of the application, its substantive examination, and the grant of a patent, or the refusal of the application, in accordance with the legal provisions of the European Patent Convention (EPC). The grant procedure is carried out by the EPO under the supervision of the Administrative Council of the European Patent Organisation. The patents granted in accordance with the EPC are called European patents.

G 1/05 and G 1/06 are decisions of the Enlarged Board of Appeal (EBA) of the European Patent Office (EPO) that were issued on 28 June 2007 and answer questions relating to divisional applications under the European Patent Convention (EPC). The two decisions were published in the Official Journal of the EPO in May 2008.

Article 123 of the European Patent Convention (EPC) relates to the amendments under the EPC, i.e. the amendments to a European patent application or patent, and notably the conditions under which they are allowable. In particular, Article 123(2) EPC prohibits adding subject-matter beyond the content of the application as filed, while Article 123(3) EPC prohibits an extension of the scope of protection by amendment after grant.

Under case number G 3/08, the Enlarged Board of Appeal of the EPO issued on May 12, 2010 an opinion in response to questions referred to it by the President of the European Patent Office (EPO), Alison Brimelow, on October 22, 2008. The questions subject of the referral related to the patentability of programs for computers under the European Patent Convention (EPC) and were, according to the President of the EPO, of fundamental importance as they related to the definition of "the limits of patentability in the field of computing." In a 55-page long opinion, the Enlarged Board of Appeal considered the referral to be inadmissible because no divergent decisions had been identified in the referral.

Under Article 82 EPC, a European patent application must "...relate to one invention only or to a group of inventions so linked as to form a single general inventive concept." This legal provision is the application, within the European Patent Convention, of the requirement of unity of invention, which also applies also in other jurisdictions.

During the grant procedure before the European Patent Office (EPO), divisional applications can be filed under Article 76 EPC out of pending earlier European patent applications. A divisional application, sometimes called European divisional application, is a new patent application which is separate and independent from the earlier application, unless specific provisions in the European Patent Convention (EPC) require something different. A divisional application, which is divided from an earlier application, cannot be broader than the earlier application, neither in terms of subject-matter nor in terms of geographical cover.

Under the European Patent Convention (EPC), a petition for review is a request to the Enlarged Board of Appeal of the European Patent Office (EPO) to review a decision of a board of appeal. The procedure was introduced in Article 112a EPC when the EPC was revised in 2000, to form the so-called "EPC 2000". A petition for review can essentially only be based on a fundamental procedural defect. Its purpose is not to obtain a reconsideration of the application of substantive law, such as points relating to patentability. The petition is a restricted form of judicial review, limited to examining serious errors of procedure which might have been committed by the Legal or Technical Boards of Appeal, prejudicing the right to a fair hearing of one or more appellants. Before the entry into force of the EPC 2000 in December 2007, it was not possible for a party who did not have his requests granted in an appeal to challenge the final decision of the Legal or Technical Board of Appeal on any grounds.

Under the European Patent Convention (EPC), any third party –i.e., essentially any person– may file observations on the patentability of an invention which is the subject of a European patent application or, after grant, subject of a European patent, especially to draw the attention of the European Patent Office (EPO) to some relevant prior art documents. This is a form of public participation in the examination of patent applications.

In case G 1/15, the Enlarged Board of Appeal of the European Patent Office (EPO) affirmed the concept of partial priority. That is, a patent claim in a European patent application or European patent may partially benefit from the priority of an earlier application.

G 1/11 is a decision issued on 19 March 2014 by the Enlarged Board of Appeal of the European Patent Office (EPO), holding that a Technical Board of Appeal rather than the Legal Board of Appeal is competent for an appeal against a decision of an Examining Division refusing a request for refund of a search fee under Rule 64(2) EPC, which has not been taken together with a decision granting a European patent or refusing a European patent application. In other words, the decision deals with the delimitation of competence between the EPO's Legal Board of Appeal and its Technical Boards of Appeal.

G 1/09 is a decision issued on 27 September 2010 by the Enlarged Board of Appeal of the European Patent Office (EPO), holding that, following refusal of a European patent application, the application remains pending until the expiry of the time limit for filing a notice of appeal, so that a divisional application under Article 76 EPC may be filed even after the refusal of an application. More specifically, the divisional application may be filed until expiry of the time limit of two months for filing a notice of appeal under Article 108 EPC.
