Intellectual Property

Our Intellectual Property (“IP”) attorneys handle all types of patent, trademark, copyright, trade secret, Internet, and domain name matters for our clients, as well as false advertising, defamation, and other unfair competition matters. We successfully represent clients on both sides of the issues, from smaller companies accused of infringement to large corporations policing and protecting their famous brands.

We assist with all phases of litigation, including the development and review of pretrial discovery and the creation of economic and financial models to prepare and present defensible and accurate analyses.


YLG lawyers have extensive experience analyzing complex copyright issues that are of critical importance to businesses and nonprofit organizations. We aggressively protect clients’ copyrights in federal and state courts, and before the U.S. Copyright Office.

Trade Secret and Non-Compete 

We handle trade secret and non-compete disputes for a range of sophisticated technology companies in a multitude of industries.  We provide comprehensive representation — from pre-litigation trade secret counseling and portfolio management to prosecuting and defending trade secret enforcement actions and trade secret misappropriation claims.

Patent Controversies

In many patent disputes, the ability and willingness to take a case to trial can be critical to winning or reaching a favorable settlement. Our lawyers have vigorously defended clients from pretrial Markman hearings through trial and appeal, achieving favorable claim rulings. Our decades of experience litigating in prominent patent litigation jurisdictions make us well aware of the predilections of particular judges and the attitudes, biases and decision-making processes of juries. Armed with this knowledge, we are able to devise litigation strategies accordingly.
