Straightforward practice with slower examination than its neighbours. Filing early is the difference between a launch on schedule and a launch waiting on a certificate.
Utility innovations need only novelty, not inventive step, which makes them a practical fallback when a full patent looks unlikely. Designs must be new at filing — publish first and you lose the right.
Build the timeline into your launch plan, or file well ahead of it.
Clear them at the search stage rather than arguing them later.
Marks touching these areas are examined sensitively. Ask before you design packaging around them.
Keep dated commercial evidence from first sale.
