When patent ownership requires enforcement, Kolisch Hartwell helps take action against patent infringers. And when a client receives an unexpected cease-and-desist letter, we’re well prepared to represent and defend their best interests.
Our firm’s founder, J. Pierre Kolisch, is one of a small group of attorneys distinguished by having argued patent law before the U.S. Supreme Court. Kolisch Hartwell attorneys have litigated patents in federal District Courts around the country, and have represented clients before the U.S. Circuit Courts of Appeal for the Ninth and Federal Circuits in numerous cases.
Our Patent Enforcement services include:
- Cease-and-desist and patent litigation We enforce patent rights through demand letters, preparing and filing complaints in Federal District Court and the International Trade Commission, negotiating settlements and, when necessary, fully contested patent litigation. We work quickly and efficiently to ensure that our clients’ patent rights are respected.
- Patent infringement defense Our experienced team of patent attorneys defends clients against assertions of patent infringement. Kolisch Hartwell has extensive experience and a highly successful track record in obtaining favorable claim construction and other rulings that can result in an early judgment of noninfringement. For a recent example, see TMI Products, Inc. v. Rosen Entertainment Systems, L.P. (Fed. Cir. 2015).
- Invalidity searches Determining the likely validity of a competitor’s patent claims is critical to the ability to make sound business decisions. We coordinate in-depth patent searches to develop strong invalidity positions for patents being asserted, or that could be asserted, against our clients.
- Post-grant proceedings The America Invents Act, signed by President Obama on September 16, 2011, was an overhaul of the U.S. patent system that gave rise to a variety of new and modified invalidity proceedings in the USPTO. Kolisch Hartwell can assist with all of these, including Post Grant Review (PGR), Ex Parte Reexamination and Inter Partes Review (IPR). Using these proceedings, we can defuse potential infringement threats before they materialize. We can also defend companies’ patents against post-grant invalidity challenges brought by others.
