Prior to litigation, an extensive early case analysis is performed to outline the facts of the case, identify the case’s strengths, and determine any weaknesses. Afterwards, the most effective means of achieving a favorable resolution are determined, including whether litigation should be avoided and a settlement is advisable. 

Our skilled litigation strategy is customized with the clients' oversight. We believe that a strong partnership between counsel and client, along with advocacy and effective communication, will yield the optimal outcome for our clients. As each case is highly individualized, we have the ability to collaborate with veteran litigators when stakes are high and a larger team is needed. As with all of the areas of law we practice, IP Patent Resource and the Law Offices of David Romero strongly believe that every decision should be made with the client's best interest in mind.
