Porter Hedges’ patent litigators handle patent cases from pre-suit investigations to filing to resolution. Our attorneys are experienced advocates for both patent owners and accused infringers in a wide variety of technology areas including oilfield equipment, electronic manufacturing devices, wireless communication devices, chemical catalysts, and genetically modified crop plants.

They have represented clients in patent trials before district courts across the country, appeals before the U.S. Court of Appeals for the Federal Circuit, and appeals before the Supreme Court of the United States. Porter Hedges’s patent litigators leverage a deep knowledge of patent law, technical backgrounds, and proven experience to create and implement legally and technically comprehensive litigation strategies for our clients’ cases.

With a focus on complex patent litigation, our patent litigators are adept at breaking down highly technical inventions into understandable components and creating an effective jury presentation using compelling themes that best tell our clients’ stories.  Over the past several years, patent litigation has become increasingly complex, with parallel inter partes review proceedings, early patent eligibility decisions, and continuing developments in patent damages law. Our patent litigators have developed creative solutions to confront litigation obstacles and to maximize client resources in this increasingly complex patent litigation environment. During all phases of the litigation, our attorneys are concentrated on delivering the best possible resolution for each unique case and providing comprehensive patent litigation support to in-house counsel and clients.

In addition to patent litigation before district courts, Porter Hedges’s patent litigators have handled post-issuance review proceedings including inter partes review proceedings before the Patent and Trademark Appeal Board. Our attorneys also have substantial experience mediating and arbitrating claims involving intellectual property disputes and counseling clients about alternative dispute resolutions.

Trademark Litigation

Trademarks, trade names, trade dress, and service marks are valuable assets that must be protected from unauthorized use. Conversely, businesses using generic, unprotected product names or slogans may also require protection against claims that they have violated others’ trademarks and trade names. Our trademark litigators are experienced in researching and developing evidence to both assert and defend against these types of claims. Our lawyers litigate registered and common law trademark, trade dress, and service mark infringement claims to resolution in state and federal courts, both at trial and on appeal.
