Specification is the most important document in the entire Patenting procedure. We strongly recommend that you consult an Attorney before finalizing the specification. There are two types of specification provisional and complete.
Provisional Specification is logged to achieve earliest priority date. When the inventive concept is in its formative stages, and a lot of final details of the invention have to be worked out in future, it is better to log a provisional specification. On the other hand, if every thing about the invention is known and the invention can be commercialized or marketed the next day, it is better to log the complete specification straight away.
If a provisional specification is followed by a Complete Specification, the Applicant will also have to log the declaration of inventorship as in Form 5.
If a Complete Specification is not logged within 12 months of logging the Provisional Specification, the Patent Application will be deemed to have been abandoned.
