I am seeking to start patenting something, and have reached out to an organization that claims to be able to help with the patenting process.
They want to do something they call a Formal Patent Search of Classification, and to charge me for it, before starting to work on the patent application itself.
What is this Formal Patent Search of Classification? I haven't been able to find any information on it online. Does it differ from a preliminary patent search (as explained on the CIPO website) in any meaningful way?
