  Timing depends on the Department of Intellectual Property (DIP) queue, how complete your file is, and public holidays.

We give you a realistic IP trademark search clearance timeline before starting and update you as it progresses.

  There are two components: official government fees passed through at the published rate, and our professional fee, which depends on scope, document volume and urgency of IP trademark search clearance.

• Q916016. What happens if IP trademark search clearance is rejected or returned for correction?

  First we obtain the written reason from the Department of Intellectual Property (DIP), then separate formal defects (fixable and quickly refiled) from substantive or eligibility issues (which need a change of approach).

• Q916022. Does IP trademark search clearance also need an English or target-language translation?

• Q916024. Should I handle IP trademark search clearance myself or use a service provider?

  Doing it yourself saves the professional fee but leaves you carrying the risk on document format, queueing and travel time, plus shifting the Department of Intellectual Property (DIP) practice.

• Q916026. Is there an express option for IP trademark search clearance?

• Q916032. What risks should I know before starting IP trademark search clearance?

  The main risks are destination rules changing mid-process, historic documents that no longer match current facts, and deadlines so tight that no correction round is left.
