Areas of Practice


Negotiating the protection of patent rights is often a daunting task. We tailor our services to your specific objectives and finances with a view to the future of your business. Our legal, scientific and business expertise enables us to guide you efficiently and effectively through the entire patenting process.


Trademarks are intrinsically associated with a company's image, and form one of the most important assets of any business. Used wisely, they help establish business reputation, generating goodwill and repeat customers.


Our experienced professionals offer a full complement of services relating to the protection and preservation of copyright in all areas. From registration to licensing, to the assessment of infringement risks and litigation, we can assist you in all matters regarding copyright.

Industrial Designs

The success of an industrial design depends on its protection. The success of a product in today’s marketplace depends not only on its functionality, but on its aesthetic appeal. As a result, companies invest heavily in industrial design and protecting this valuable intellectual property right is essential.

Domain Names

No longer merely "street signs" for your website, domain names have evolved to function as online brands. As more businesses seek to establish an internet presence, disputes involving the ownership and use of domain names are increasing.


The important thing is not to stop questioning. Curiosity has its own reason for existing.
