Trademark audit

How much are your trademarks worth, and what is the value of your total intellectual property portfolio? It is important to know, because the value of your intellectual property contributes to the value of your business as a whole. This might be a crucial factor, for example, if a due diligence study needs to be carried out in the event of a merger or takeover, or if you want to attract investors. A trademark audit will give you all the insight you need.


Why carry out a trademark audit?

A trademark audit is an important step in determining the value of your trademarks and thus of your company as a whole. In the event of a merger or acquisition, a trademark audit would be carried out as part of the overall financial audit, commonly known as due diligence. But it is a good idea to carry out a regular trademark audit even if a merger or takeover is not in the pipeline. This is a very efficient way of ensuring that your trademark portfolio is up-to-date and adding value for your business.


Audit method

A trademark audit consists of two phases:


  1. Trademark audit phase 1: verification
    During the verification of the current portfolio, NLO Shieldmark checks all the details for correctness. Often the details on file are not always completely accurate. We also crosscheck the details on file with the various official registers. For this we use the VIP® (Verification Intellectual Property) system developed by NLO Shieldmark, which makes it possible to verify the data worldwide in an efficient way.

  2. Trademark audit phase 2: validation
    The verification phase confirms the current status of the trademarks. The portfolio then has to be validated to make sure all the details are up-to-date. This often identifies omissions, such as incomplete and/or missing registrations, missing countries or incorrect holder details. It also often reveals situations where there is unnecessary expenditure on obsolete and non-essential registrations. Recommendations are then provided about the action to be taken in such cases.

Fake invoices

Fake invoices are unfortunately a well known problem among trademark owners. A fake invoice is a misleading invoice (or letter) which reffers to a trademark, design, patent or patent application. A payment is requested for a publication in a register or to extend the validity of a registration.They use names like Worldwide database or Trademarks and Patents, Euro IP Register, International Patent & Trademark Database.
