A patent in Turkey has been registered WITH the number TR 1998 02335 B.

Can I use either sentence?

Answer

Registered by a person.
Registered with a number.
Also possibly 'under a number'?

Answer

The second sentence is correct.

"Registered by" would normally be followed by the person doing the registering. e.g. "The patient was registered by the nurse".

Answer

Yes you can use either sentence.
