Although the Indian patents act requires the filing of a power of attorney (POA) along with the patent application, my understanding is that this can be filed at a later stage as well. And attorneys routinely file this later (after date of filing the application). Is this correct?
Do our readers know what the global practice is in this regard? Do the USPTO, EPO, JPO etc require the power of attorney to be filed on the date of filing of the patent application or later? Or are they generally lax about this and do they permit a later filing (or does their statute or other notification etc permit such later filing of the POA).
And does the same position apply with respect to trademark filings as well?
