Green IPOs: Accelerating Prosecution of Green Tech Patent Applications Part II

By Ari Rollason, Associate

Following on from our article last week running through the green tech accelerated prosecution schemes in: the UK, the USA, Japan, China, and Republic of Korea; this article will cover more schemes available around the world.

Accelerated Prosecution Schemes

Canadian Intellectual Property Office (CIPO) – Canada

CIPO allows applicants to advance examination of a patent application where “An applicant requests such an advancement and submits a declaration that the application relates to technology the commercialization of which would help to resolve or mitigate environmental impacts or conserve the natural environment and resources” [1].

In order to use the advanced examination process, applicants should submit a letter including:

  1. a request for advanced examination,
  2. a statement indicating that the application relates to technology that if commercialized would help to resolve or mitigate environmental impacts or to conserve the natural environment or natural resources, and
  3. if the application has not yet been published, an early publication date [2]. Unlike, for example, the UK, a request for accelerated examination of an application relating to green technology can only be granted if the application is open to public inspection [3].

Once a request for advanced examination for a green technology has been processed by CIPO, a first office action can be expected within 3 months [2].

IP Australia – Australia

IP Australia allows applicants to request faster examination of their applications at no additional cost, so long as the applicant can indicate a suitable reason as to why they think the application should be expedited. Although the reasons that may be considered ‘suitable’ are not restricted, one of the three explicit fast track options provided by IP Australia is “Fast Track for Green Technology” [4]. IP Australia provides no formal definition of what constitutes a green patent; an applicant may be able to obtain accelerated prosecution if they can provide a statement justifying that the invention is an environmentally beneficial or ‘green’ technology.

Applicants may make a request for accelerated examination for their application either in writing or by phone [5]. Where a request for expedited examination has been allowed, IP Australia aims to issue a report (clear or adverse) within 8 weeks from the date of the request.

Instituto Nacional da Propriedade Industrial (INPI) – Brazil

INPI offers a Green Patents program to accelerate examination of patent applications related to technologies directed to the environment [6]. The program defines green technology as including technologies from the following areas: alternative energy, transport, energy conservation, waste management, and agriculture [7]. An expanded list detailing examples falling under each category [8], along with a step-by-step guide on how to participate in the program [9], is available on the INPI website.

There is an official fee associated with using the scheme, with a discount available for individuals and micro-enterprises, and applicants can participate by filling out an online form [7].

Israel Patent Office (ILPO) – Israel

“Green” applications are eligible for expedited examination at the ILPO at the request of the applicant [10] [11]. Applicants who wish to expedite examination on an application can request this by filing an evidenced request explaining how the invention helps to advance environmental protection. If a request is granted, the ILPO will aim to produce a search and examination report within 3 months of classifying the invention as “green” [12].

Examples of areas of technology that would fall within the scope of “green” applications provided by the ILPO include:

  1. preventing causes of global warming,
  2. reducing air or water pollution,
  3. promoting non-polluting agriculture, and
  4. relating to alternative energy sources [13][14].

There is no official fee associated with accelerating examination at the ILPO for green applications [15].

Taiwan Intellectual Property Office (TIPO) – Taiwan

TIPO offers an Accelerated Examination Program (AEP) that allows applicants to request accelerated examination on applications for inventions relating to green technologies [16]. TIPO defines green technologies as any one of the following:

  1. technologies for improving energy conservation and for developing new sources of energy, or renewable energy vehicles, or
  2. technologies for carbon reduction and resource saving.

Applicants wishing to enter the AEP should file an AEP request form, along with a written explanation as to why the claims of the invention relate to the green technology areas recognised in Taiwan (and may support this explanation by providing supporting documents such as the application specification or drawings). Unlike many other patent offices, TIPO charges an official fee for the AEP [16].

TIPO estimates that examination results on AEP applications (e.g. notification of responsive examination opinions, final notice, or written decision of examination) will be issued 6 months after all the relevant documents have been received, however this may vary depending on the green technology field of the application [16].

Finnish Patent and Registration Office (PRH) – Finland

PRH allows applicants to use a fast-track processing system if a national patent application (including divisional applications) relates to bioeconomy, circular economy, or clean technology solutions [17].

In order to use the fast-track processing system, a request form should be included on filing along with the application [18]. If the request for fast-track processing is accepted, PRH will issue a first Office Action within 3 months after the application has proceeded to technical examination, and will issue a second Office Action 2 months after a reply to the first Office Action has been received [17] [18].


Many national IP offices offer accelerated processing for applications relating to environmentally friendly or “green” technologies. However, what constitutes a “green” technology varies between offices, and some schemes are only available to certain applicants. Some IP offices also have additional requirements, such as early publication or additional databases on which accelerated applications are published. If you think one or more of these schemes may be useful for your business, please contact the authors or your usual HLK contact.
