How far do prior art searches go?

do we stop at the priority date or at the actual filing date?


in invalidity cases, prior art searches go beyond the actual filing date because they may lead to relevant further prior art, despite being published after the relevant date for a claim. That will involve further work after studying these publications.

I would go for one year after the actual filing date for an invalidity prior art search.

For patentability searches, your question does not make sense.

I learned something new. Thanks!

I think we have to differentiate between the legal view and the searcher view. For the conclusion, the priority date /actual filing date for sure is a binding date to have a look at. For your search to have a look at the priority date/actual filing date is just recommendable. Its wise too include the rest of the year to enhance your search. It may deliver you over citations search some new angles.
