Our professionals bring a variety of perspectives to each matter due to our uniquely broad experience in IP enforcement and patent procurement.

The Gardella Grace team has directed multinational enforcement campaigns, procured large international patent portfolios, defended and defeated patents in post-grant proceedings, licensed IP portfolios, developed and implemented defensive and risk mitigation strategies for large corporations, and executed trade secret protection programs.

Our Leadership

Greg H. Gardella

Post-Grant Proceedings | Patent and Trade Secret Litigation | Patent Procurement

Mr. Greg H. Gardella is the Managing Principal of Gardella Grace and spearheads the firm’s Post-Grant Proceedings practice.  He is recognized as a premier national expert in the field of post-grant proceedings. This aptitude derives from a synergy developed through years of experience as a litigation attorney as well as years of experience in patent prosecution.


His combined background as litigation attorney, prosecution attorney, and post grant attorney has further positioned Mr. Gardella as a premier IP strategist. Mr. Gardella specializes in developing and coordinating assertion efforts, valuation and monetization efforts, and trade secret protection programs on behalf of the firm’s clients.


Mr. Gardella has been named one of the Best Lawyers in America for multiple consecutive years and has received various awards and recognition from Managing IP Magazine, Intellectual Asset Management, Super Lawyers and Who’s Who Legal.

Natalie J. Grace

Patent Procurement | Post-Grant Proceedings

Ms. Natalie J. Grace, Principal, has worked hand-in-hand with Mr. Gardella for more than a decade to build strong portfolios on behalf of the firm’s clients. Ms. Grace specializes in coordinating with the firm’s post-grant and litigation efforts to bolster clients’ defensive and offensive positions through rapid, strategic patent procurement.


Ms. Grace relies upon engineering skills built during a nearly decade-long career in software design to successfully develop strong patent invalidity positions used in the firm’s post-grant petition filings through deep, thoughtful analysis of prior art combinability and thorough explanation of methods and motivations to combine prior art. These skills further aid in identifying holes in combinability arguments presented by both patent examiners and post-grant petitioners as well as in identifying inconsistencies and inaccuracies presented in declaration evidence supplied by experts.

Cook Alciati

Mr. Alciati regularly represents clients in district courts around the country and represents clients in inter partes review proceedings before the United States Patent and Trademark Office’s Patent Trial and Appeal Board.

Areas Of Expertise

Patent Procurement

Overly broad patents are difficult to enforce and easy to defeat. We ensure every patent specification provides rich and detailed descriptions of all potential alternative implementations to craft patent coverage that blocks competitors from a given space.

Post-Grant Proceedings

Our team has handled some of the highest stakes post-grant matters ever adjudicated by the United States Patent and Trademark Office, often running into the billions of dollars. We regularly serve as lead counsel for both challengers and patent owners.

Patent and Trade Secret Litigation

Our enforcement campaigns have included infringement suits in the United States, Europe and Asia involving both patent infringement and trade secret misappropriation. Most cases involved co-pending oppositions and inter parties review proceedings before foreign and domestic patent offices.

We’re unique among small patent firms in our team’s extraordinary breadth of intellectual property experience and expertise.
