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 attorneys-at-law 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 attorneys-at-law of course assist in and take on IP litigation cases.

Unlawful patent ownership and how to avoid it

The development of new inventions is often characterized by the cooperation of different parties.
