Among other companies, members of our team have provided legal and technical counsel to a wide variety of companies, including ASM Industries, Bayer, Baxter, Biorad, Bioran, EcoScience, Ericsson, GE, Ingersoll-Rand, and Pacific Dunlop. Whether you need to file an application for a patent, trademark or copyright, or are involved in litigation, we have an experienced team for the project.

        Though relatively modest in size, we offer as good or better quality work than many larger firms, more flexibility, and a more affordable price. This is due, in part, on the fact that each of our IP specialists has many years of experience. On each project, our philosophy is to assign the project to the best person for the job who can complete it in the most cost efficient manner.
