Heim, Payne & Chorush LLP

Heim, Payne & Chorush (HPC) represents plaintiffs and defendants nationwide in patent and antitrust litigation in a broad range of technologies. HPC attorneys have proven technical and legal skills that enable them to handle all facets of IP disputes and obtain the best possible results for clients.

The firm provides counsel to large and small business entities, as well as individuals at both the state and federal levels regarding IP litigation. The firm has also developed extensive expertise in representing clients in post-grant proceedings at the US Patent and Trademark Office, including inter partes review proceedings, re-examinations and other contested proceedings. The firm employs attorneys holding various types of technical degrees and having the legal and technical expertise to handle highly complex cases.

The founding partners each have vast experience in evaluating patent portfolios and developing strategies to enforce and license those portfolios. They are skilled litigators, able to understand and explain highly complex technical and legal issues to judges and jurors, and are known in the patent community for their abilities and results. The firm also has a tremendous amount of experience in patent infringement cases relating specifically to antitrust cases in the pharmaceutical industry. Again, the founding partners have invaluable experience in evaluating and developing strategies to successfully navigate these antitrust cases.

The firm’s attorneys have the specific education and experience for prosecuting and defending actions in the federal and state courts, both at the trial and appellate levels in the IP areas relating not only to infringement, but also to unfair competition, trademark infringement, copyright infringement, trade secret misappropriation, breach of contract, non-compete covenants, tortious interference, fraud and other areas.

The firm often shares the risks and rewards with clients, thereby aligning interests to produce a more synergistic relationship. HPC attorneys devote a significant portion of their time to litigation under fee agreements that link the fees to the results achieved. In addition to standard hourly rate arrangements, the firm has developed fee arrangements with clients that range from partial contingent fees that reduce hourly rates for a stake in the outcome, to full contingent arrangements. On the defence side, the firm is open to using reverse contingent fee arrangements where the amount saved for clients determines compensation.

HPC attorneys treat every case as a representative model of the firm’s abilities and integrity, and work on behalf of clients has resulted in the successful resolution of several nationally and internationally publicised cases. HPC takes pride in its ability to partner with other attorneys and firms to bring the best possible trial team together for the benefit of the client. That is why so many clients and co-counsel contact HPC when they have a new case.

Each HPC attorney has one or more degrees in electrical engineering, computer engineering, chemical engineering, aerospace engineering, physics, chemistry or biochemistry, and many are registered to practise before the US Patent and Trademark Office. Six HPC attorneys have completed judicial clerkships at venues including the US District Court for the Eastern District of Texas, the Southern District of Texas and the US Court of Appeals for the Federal Circuit. In addition to the Chambers USA recognition in Intellectual Property Litigation, HPC is ranked among the best in IP Litigation and Patent Litigation by US News & World Report and Best Lawyers in America.
