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 an engineer. He brings this background and a deep curiosity to every matter he works on. Dan’s 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.

Dan recently took a leading role in a two-week bench trial for Trilliant Networks in which our team secured a full victory. Dan also had a significant role in a 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.

Representing Comcast, Dan and our Farella team obtained 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.

Representing Google, Dan was part of a trial team that secured a complete defense verdict 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, successful summary judgment rulings, and beneficial Markman rulings that have driven settlement. For trademark clients, he has obtained settlements including co-existence agreements and agreements by defendants to change their logos.
