Patent timeline

CSIR technology disclosure

Invention/idea/technology reported to R&D Outcomes Manager and the Licensing & Ventures office, where it is evaluated. A decision is made on whether to pursue patent protection.

Provisional patent application

Provides a priority date ie any similar subject matter developed or patent applications filed after the priority date do not affect the novelty of the invention application. Quicker, cheaper filing process.

0 months

Patent Cooperation Treaty (PCT) application

A centralised application, search and examination process (but not a

patent-granting authority). Retains the option for the patentee to obtain patents in multiple countries, while deferring the cost of a large number of individual applications.

12 months from the date of first filing

International Search Report & Written Opinion issued

An international search is performed to find information that has been

made available to the public in any form before the priority date that

might be relevant to a patent’s claims of novelty and inventiveness, allowing the patentee to decide whether it is worth pursuing the patent application further.

16 months

Publication

PCT application is published and can be viewed by the public.

18 months

Demand for International Preliminary Examination

Optional step in the process, for cases where the patentee might wish to respond to the Written Opinion.

19 months

International Preliminary Report on Patentability (IPER)

Where no Demand is filed, this will follow the Written Opinion. Where a Demand has been filed, this might differ from the Written Opinion.

28 months

National phase entry

Patent applications filed in each country/region in which the patentee

desires protection. Some national/regional patent offices accept the results of the IPER, while others conduct a new search and examination.
