Short answer. Your appeal is perfected on your side once you file the notice of appeal in due time, but Rule 41, Section 9 says the court loses jurisdiction over the case only once the appeals of all parties are perfected and every party's time to appeal has expired — not the moment you alone file.

What the law says

A party's appeal by notice of appeal is deemed perfected as to him upon the filing of the notice of appeal in due time.

What the law says

In appeals by notice of appeal, the court loses jurisdiction over the case upon the perfection of the appeals filed in due time and the expiration of the time to appeal of the other parties.

Two different moments, easy to confuse

Section 9 draws a distinction that is easy to miss: perfection of an appeal "as to" a particular party happens the moment that party files a timely notice of appeal, but the trial court's loss of jurisdiction over the case as a whole is a separate event that depends on more than just one party's filing. A losing party who files a notice of appeal has perfected their own appeal immediately, but that alone does not instantly strip the trial court of authority over the case if other parties are still within their own period to appeal.

Why the court retains jurisdiction until every party's window closes

In a multi-party case, or any case where more than one party could potentially appeal, the rule waits for the appeals of parties who choose to appeal to be perfected and for the time to appeal of the other parties to expire before the trial court's jurisdiction ends. This protects against a scenario where the trial court loses authority to act the instant one party appeals, while another party who has not yet decided whether to appeal is still within the period to do so — the case needs to be genuinely settled as to everyone before jurisdiction fully transfers upward.

What the trial court can still do in the meantime

Even after perfection, and prior to the actual transmittal of the record to the appellate court, the rule allows the trial court to continue issuing orders that protect and preserve the rights of the parties on matters not involved in the appeal itself, approve compromises reached by the parties, permit appeals by indigent litigants, and allow the withdrawal of an appeal. That narrow band of continuing authority exists because a case does not become instantly frozen and unmanageable the moment a notice of appeal is filed — practical matters unrelated to the merits being appealed still need somewhere to be handled.
