Please take a look at our professional’s backgrounds below. Our firm values relevant industry experience in our professionals as you can be seen in our backgrounds. We believe that engineering experience designing and developing products is essential experience for someone who is drafting and prosecuting patents. Many firms may utilize patent attorneys who went directly from engineering college right into law school, or attorneys who were employed in peripheral areas of engineering such as sales or applications engineering. That may get the job done, but we believe there is no substitute for actual experience in designing a product and getting it into production.
