I've just been having this exact same problem. Few things:

• sendNotifications is deprecated, you should be using sendUpdates instead.
• The optional Params don't go on the event itself - they go in the request. So you end up with:

$event = $service->events->patch(
    $calendarID, 
    $eventID, 
    $event, 
    ['sendUpdates' => 'all']
);
