Patent criticality
Published is not granted
My application is published. Can I stop competitors now?
Publication makes your application public. It does not make it enforceable. Between publication and grant you have privileges and rights as if the patent had been granted, but you cannot bring infringement proceedings until it actually is.
What publication does
It puts the specification in the public domain, where it becomes citable prior art against everyone else. It opens the pre-grant opposition window. And it starts the period from which the applicant has, on grant, rights in respect of the intervening period - but proceedings cannot be started until grant.
It does not mean the claims are allowed. Published claims are simply the claims as filed, and they frequently change substantially before grant.
Why the confusion is expensive
Two ways. Applicants tell customers and investors that they have a patent when they have a published application - which is a statement that can be challenged, and which section 111 and the marking provisions make risky. And they assume a competitor's published application is a granted patent, and change their product for no reason.
Read the status, not the document type.
Section 11A of the Patents Act 1970, including the rights on and from publication; section 25(1) for pre-grant opposition.
In marketing material, say patent applied for or patent pending, never patented, until grant.
Marking products as patented on the strength of a published application.
Competitor documents labelled A rather than B - the difference between a published application and a granted patent.
