In certain circumstances, the Act and Regulations may also determine further priority dates different from the date of filing of the complete specification. The Regulations also set out the procedure for determining priority dates when the claimed invention relates to a micro-organism.
The procedure varies depending upon certain timing requirements as indicated below. In this situation the priority date is the filing date of the priority application. The Regulations recognise in the same way as in sec 41 that an invention involving a micro-organism may not be practically disclosed in a written specification and that a deposit under the Budapest Treaty should be taken into account for the purpose of determining priority dates.
This is implemented on the basis that the complete specification meeting the requirements of sec 6 c is specified as a priority document for the purpose of sec 43 and, under sec 41, is taken to provide an enabling disclosure of the invention including the micro-organism.
The priority date, however, is the filing date of the priority application, provided the other conditions are met, including that the deposit is made on or before that date.
The priority date of a claim is the date of filing of a specification which first discloses the claimed invention in a manner that is clear enough and complete enough for the invention to be performed by a person skilled in the art and from which the claim is entitled to claim priority. The disclosure required in a priority document is substantially the same as the enabling disclosure required for the purposes of sec 40 2 a see 2. If a priority document is silent with regard to any essential element of a claim, the claim is not entitled to an earlier priority date.
In particular, if a claim in a priority document is broad enough to cover a certain technical feature, it does not follow that it discloses that feature for the purpose of establishing priority. A claim may properly derive priority from a prior specification where the specific matter added to the disclosure of that specification is common general knowledge Scherico Ltd.
For example, if the prior specification does not disclose the material of which a particular part is made, but it is common general knowledge at the relevant date that such a part may be made of a certain material, then the specification may be regarded as disclosing the part made of that material.
If examiners are unaware that certain matter is common general knowledge, it may be assumed not to be until evidence to the contrary is provided. The extent and nature of the evidence required is the same as that required of examiners citing common general knowledge during examination.
Where an invention resides in a selection, the claims of a complete specification will not be enabled by the disclosure of a priority document, if the priority document did not provide a clear enough and complete enough enabling disclosure of the inventive selection. However, where a feature in a claim is merely restricted to a subset of alternatives taught in the specification and the alternatives are taught in the priority document, the priority document will contain a sufficiently enabling disclosure of the claimed subset.
A claim may possess more than one priority date. Under sec 43 3 , where a claim of a complete specification defines more than one form of an invention, then the claim must be treated as constituting a separate claim for each form of the invention for priority date purposes. What do I need to remember? Your innovation is secured by a patent from the priority date. You can then make your invention public. If you want to know when a patent expires, you will need to take the filing date as a basis and add 20 years.
That will generally be sufficient although there are exceptions. You can take legal action against infringers from the moment your patent has been granted.
Prior to this date there are other avenues that can be pursued. If you want to know for sure that a patent is still valid, you should check this out with a patent attorney. A patent may appear to be valid, but if not all of the conditions have been met, the right may be invalid or have expired.
How do you make a patent Patent law on lucrative AI Where only a single patent application is involved, the priority date would obviously be the filing date of the sole application. If an applicant has filed a number of related patent applications , the priority date would be the filing date of the earliest patent filing that first disclosed the invention. Known as the priority application, the earliest patent filing may comprise a provisional patent application, a nonprovisional patent application or a foreign application.
The term may also refer to the earliest filing date of a particular feature of an invention. Therefore, it is possible to have multiple priority dates if new features were subsequently added in related applications. The priority date is how we determine whether another patent filing or publicly available document qualifies as prior art against your patent application.
Generally, patent applications filed and publicly available documents published before your priority date will be considered prior art. Yes 0 No 0. Baker Library Bloomberg Center. Baker Library. Databases Ask Us! Or, ask a new question! Baker Library Fast Answers.
