Present Perfect Continuous Tense : Possessive Verb
While the Present Perfect Tense can be used with “have” to show possession, the Present Perfect Continuous is not used to show permanent possession. Instead, when used with “have” (having), it expresses ongoing experiences or temporary states that started in the past and are continuing or have just ended.

Correct Usage (for experience/state):
I have been having a headache since morning.
She has been having trouble with her laptop.
They have been having a good time.
Incorrect Usage (for possession):
I have been having a car.
He has been having three phones.
These are incorrect because ownership is not expressed in continuous form.
Use Present Perfect (not continuous) for possession:
I have had a car for five years.
Conclusion:
The Present Perfect Continuous Tense highlights the duration or continuity of actions or experiences from the past up to the present. It is especially useful when discussing time-related events using phrases like “for two hours,” “since morning,” “lately,” “recently,” etc.
