AddyHart assists companies, inventors, universities, and patent professionals from Europe in obtaining and managing patent protection in the United States. We combine deep technical expertise, practical prosecution experience, and transparent pricing to help clients navigate the U.S. patent system efficiently and effectively.
Transparent Pricing
We believe clients should understand the cost of patent prosecution before work begins. For many common prosecution tasks, we offer predictable fixed-fee pricing.
Standard Office Action Turnaround
No Additional Rush Fee
We target delivery of draft Office Action responses within two weeks after receiving the USPTO communication and the information needed to prepare the response.
Any applicable USPTO extension-of-time fees remain the client’s responsibility.
