What Clients Say

Reviews frequently mention successful outcomes in U.S. utility patent prosecution, including cases that initially faced rejections or complex examiner objections. Several clients report that persistence and well-framed responses led to patent grants after earlier challenges. Customers often note the firm’s experience with international filings, with multiple references to patents obtained in Europe, Asia, South America, and particularly China—an outcome some clients viewed as unlikely at the outset but ultimately achieved.

Clients also emphasize strategic planning: reviewers highlight long-range portfolio development, multi-application roadmaps, and an ability to tailor filing strategies to product and market goals. Startups and individual inventors commonly point to a clear, patient communication style that demystifies the process, with explanations of tactics used during examiner interactions and how each step fits into broader IP protection. A number of testimonials describe multi-year relationships—spanning five to six years or more—suggesting ongoing support from initial provisional filings to global expansion of protection.

Related themes include accessibility and responsiveness (easy to reach for questions), fair and competitive rates for a specialized practice, and flexibility in working methods. In more technical projects, clients report the ability to collaborate closely on drafting—ranging from attorney-led writing to client-authored technical sections with legal review—while maintaining compliance with examiner expectations. One reviewer credits the firm’s patent work as a contributing factor to a successful company acquisition, connecting the value of a well-aligned patent portfolio to tangible business outcomes.
