Biography
Dan Callaway focuses his practice on intellectual property litigation and counseling, including patents and patent portfolios, trade secrets, and trademarks. His courtroom experience includes jury and bench trials in federal courts in California and Texas, appeals at the Court of Appeals for the Federal Circuit, and trials before the Patent Trial and Appeal Board.
Dan holds bachelor’s and master’s degrees in electrical engineering and spent years working as a semiconductor engineer. He brings this background and a deep curiosity to every matter he works on. His patent infringement and trade secret cases have involved integrated circuit design, storage and networking, power delivery, processor and memory design, operating system and application software, virus protection, and security. He has also worked on energy-related cases involving solar, wind, battery, and geothermal technologies. He is the inventor of U.S. Patent No. 6,794,568.
His notable engagements include:
- Lead role in a two-week bench trial securing a full victory for Trilliant Networks.
- Member of a trial team in a trade secret jury trial in the Eastern District of Texas in which Farella secured a jury verdict in favor of our client, CNEX Labs, against Huawei Technologies Co., Ltd.
- Represent Comcast in obtaining a dismissal of a complaint asserting infringement of three patents in the District of Colorado, coupled with multiple invalidations of patents at the Patent Trial and Appeal Board.
- Member of a trial team that secured a complete defense verdict for Google in Judge Albright’s court in the Western District of Texas, including a verdict that the patent was invalid.
Dan works to achieve results for his clients from the outset of a case. For example, in addition to trial victories, he has helped secure “walk-away” dismissals on behalf of his defense clients, summary judgment rulings, and favorable Markman rulings that have driven settlements. For trademark clients, he has obtained settlements, including coexistence agreements and agreements by defendants to change their logos.
Dan is a member of Farella’s AI Task Force, leading initiatives to integrate AI tools into the firm's operations.
HIs pro bono practice includes successful representation of tenants in eviction proceedings and long-term representation of a California inmate seeking habeas corpus relief.
