Summer associate program

Our highly successful Summer Associate Program is our primary source for the recruitment of new associate attorneys. Second and third year law students with undergraduate or graduate degrees in engineering, biochemistry, chemistry, physics, biology, and computer systems are encouraged to apply. Summer associates receive hands-on experience in patent and trademark prosecution and litigation and undertake a variety of projects and assignments that provide a realistic view of law firm life and work. Where appropriate and available, summer associates can attend client meetings, depositions, and court proceedings. Summer associates are assigned mentors who provide guidance, offer advice, and share their expertise. Summer associates are given feedback on their performance through formal reviews at the five-week mark, as well as at the end of the summer. Informal feedback is provided by supervising attorneys as summer associates complete various projects and assignments.
