In addition to expertise and skill in prosecuting patent applications, the attorneys in Pryor Cashman’s Patent Group effectively represent clients in complex litigations involving patent and related commercial claims. Because our patent attorneys are accomplished and experienced litigators, our clients, regardless of the complexity or size of a matter, are represented efficiently and effectively by attorneys who understand the relevant technology.

Our patent litigations often encompass multiple patents and jurisdictions, including “Section 337” claims involving imported goods before the U.S. International Trade Commission (ITC) and the U.S. Court of Appeals for the Federal Circuit.

We represent clients both in enforcing their patents and in defending them against patent claims. Our successful enforcement actions have involved patents for a variety of products, such as a cassette tape adapter for a CD-like player device; fiber optic dental handpieces; and mass spectrometry and the method of creating and measuring molecular weight of multiple charged ions.

On the defense side, our clients’ businesses have been equally varied. We have been successful in litigations involving patents for everything from payroll/currency security bags to ultraviolet water purification systems. Other patents we have successfully defended have included an automatic generation and mailing of an insurance proposal based on publicly available information; automatic telephone answering systems; a disposable pulse oximeter; a dental handpiece timer delay mechanism; and remote time and attendance billing systems.
