Patents
Make your innovation profitable by dealing strategically with your intellectual property. Our specialists will support you in words and deeds with developing and implementing an IP strategy based on your company objectives. Whether it involves a patent application, drawing up agreements or support with infringement proceedings, our style of working is to the point and completely transparent.
Trademarks & design
Registering your trademark or design means that it cannot be simply used or copied by third parties. Careful registration is important and can sometimes be fairly complex. V.O. supports you through this process. We help you to guard your creation, deal with unauthorized copying and set up a robust licence agreement. This lets you get the maximum from your ideas.
Legal services
In addition to patent and trademark services, V.O. also provides legal services. The lawyers of V.O. advise and assist in drafting and negotiating intellectual property (IP) agreements such as license agreements, Non-Disclosure Agreements (NDAs) and agreements regarding the sale of IP rights. In addition, our lawyers of course assist in and take on IP litigation cases.

The Board held that an expressly claimed alternative could not be read out of the claim merely because the patent did not teach how to perform it. As that alternative was not enabled, the patent was revoked.
